Recalls first every turn — and is honest enough to say \"I don't know\" instead of making things up.\n\n[![PyPI](https://img.shields.io/pypi/v/ultramemory-hermes?color=2dba4e&label=pypi%3A%20ultramemory-hermes)](https://pypi.org/project/ultramemory-hermes/)\n[![License](https://img.shields.io/badge/license-Apache--2.0-blue.svg)](LICENSE)\n[![MCP](https://img.shields.io/badge/MCP-Streamable%20HTTP-7c3aed.svg)](https://modelcontextprotocol.io)\n\nUltraMemory is a hosted, multi-tenant **agent-memory service**. One API key (`um_…`) = your own\nprivate tenant. This repo is the **open-source client surface** — the connect snippets, the Hermes\nprovider package, and a Claude Code recall hook. They all just call the hosted API at\n`https://api.ultramemory.us`; the engine stays a managed service (open-core).\n\n## Quick start\n\n```bash\nclaude mcp add --transport http ultramemory https://api.ultramemory.us/mcp \\\n --header \"Authorization: Bearer um_YOUR_KEY\"\n```\n\nGet a free key at **https://ultramemory.io** — no credit card required.\n\n### Or connect with OAuth — no key needed\n\nOn **claude.ai** and **Claude Desktop**, UltraMemory is a one-click custom connector: Settings →\nConnectors → **Add custom connector** → URL `https://api.ultramemory.us/mcp` → sign in when\nprompted. The server speaks **OAuth 2.1 (PKCE)** end-to-end; API keys drive all the terminal/CLI\nclients below; the OAuth connectors (claude.ai, Claude Desktop, ChatGPT) sign in without one.\n\n## Install options\n\nThree tiers — pick one (each builds on the last):\n\n### Tier 1 — UltraMemory (MCP)\n\nSimple connect: point any MCP client at the hosted endpoint and you get the nine memory tools.\n**Memory tools, no local caching.**\n\n**Claude Code** — one paste: registers the MCP server and writes the active-recall rule to `CLAUDE.md`:\n\n```bash\nclaude mcp add --transport http ultramemory https://api.ultramemory.us/mcp \\\n --header \"Authorization: Bearer um_YOUR_KEY\" \\\n&& cat >> CLAUDE.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\n**Gemini CLI** — one paste: registers the MCP server and writes the active-recall rule to `GEMINI.md`:\n\n```bash\ngemini mcp add -s user -t http ultramemory https://api.ultramemory.us/mcp \\\n -H \"Authorization: Bearer um_YOUR_KEY\" \\\n&& cat >> GEMINI.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nPrefer OAuth instead of a key? Gemini CLI also supports OAuth — add an `httpUrl` block to `~/.gemini/settings.json`, then run `/mcp auth ultramemory` inside the CLI.\n\n**Cursor** — one paste: registers the MCP server and writes the active-recall rule to `AGENTS.md`:\n\n```bash\npython3 - <<'PY'\nimport json,pathlib,shutil,time\np=pathlib.Path.home()/\".cursor\"/\"mcp.json\"; p.parent.mkdir(parents=True,exist_ok=True)\ntry:\n d=json.loads(p.read_text()) if p.exists() else {}\nexcept ValueError:\n b=p.with_name(\"mcp.json.bak-%d\"%time.time()); shutil.copy2(p,b); d={}\n print(\"Cursor: invalid mcp.json backed up to\",b)\nd.setdefault(\"mcpServers\",{})[\"ultramemory\"]={\"url\":\"https://api.ultramemory.us/mcp\",\"headers\":{\"Authorization\":\"Bearer um_YOUR_KEY\"}}\np.write_text(json.dumps(d,indent=2))\nprint(\"Cursor: wrote\",p,\"— Cursor may prompt an OAuth login; approve it (your key still attributes usage).\")\nPY\ncat >> AGENTS.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nOr use Cursor's official one-click deeplink (add your Bearer key afterwards in `~/.cursor/mcp.json`): `cursor://anysphere.cursor-deeplink/mcp/install?name=ultramemory&config=eyJ1cmwiOiJodHRwczovL2FwaS51bHRyYW1lbW9yeS51cy9tY3AifQ==`\n\n**Codex** — one paste: registers the MCP server and writes the active-recall rule to `AGENTS.md`:\n\n```bash\nmkdir -p ~/.codex && grep -q 'mcp_servers.ultramemory' ~/.codex/config.toml 2>/dev/null || cat >> ~/.codex/config.toml <<'EOF'\n\n[mcp_servers.ultramemory]\nurl = \"https://api.ultramemory.us/mcp\"\nhttp_headers = { Authorization = \"Bearer um_YOUR_KEY\" }\nEOF\ncat >> AGENTS.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first.

Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nWindsurf interpolates `${env:VAR}`: use `\"Authorization\": \"Bearer ${env:ULTRAMEMORY_API_KEY}\"` to keep the key out of the file (an unset variable silently becomes an empty string). Teams/Enterprise: an admin may need to enable the MCP Servers toggle — off by default on Enterprise.\n\n**Cline** — one paste: registers the MCP server and writes the active-recall rule to `AGENTS.md`. VS Code extension users: paste the same mcpServers block via the Cline panel > MCP Servers > Configure MCP Servers.\n\n```bash\npython3 - <<'PY'\nimport json,pathlib\np=pathlib.Path.home()/\".cline\"/\"data\"/\"settings\"/\"cline_mcp_settings.json\"; p.parent.mkdir(parents=True,exist_ok=True)\nd=json.loads(p.read_text()) if p.exists() else {}\nd.setdefault(\"mcpServers\",{})[\"ultramemory\"]={\"type\":\"streamableHttp\",\"url\":\"https://api.ultramemory.us/mcp\",\"headers\":{\"Authorization\":\"Bearer um_YOUR_KEY\"}}\np.write_text(json.dumps(d,indent=2))\nprint(\"Cline: wrote\",p)\nPY\ncat >> AGENTS.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\n**OpenClaw** — one paste: registers the MCP server and writes the active-recall rule to `AGENTS.md`:\n\n```bash\nopenclaw mcp add ultramemory --url https://api.ultramemory.us/mcp \\\n --transport streamable-http --header \"Authorization=Bearer um_YOUR_KEY\" \\\n&& openclaw mcp reload && cat >> AGENTS.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nVerify the connection with `openclaw mcp doctor ultramemory --probe` — static checks plus a live connection proof. Changing the header later? `openclaw mcp set ultramemory ''` replaces the whole server definition; run doctor --probe again after.\n\n**VS Code** — one paste: registers the MCP server and writes the active-recall rule to `AGENTS.md`:\n\n```bash\ncode --add-mcp '{\"name\":\"ultramemory\",\"type\":\"http\",\"url\":\"https://api.ultramemory.us/mcp\",\"headers\":{\"Authorization\":\"Bearer um_YOUR_KEY\"}}' \\\n&& cat >> AGENTS.md <<'EOF'\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nThis applies to terminal/CLI MCP clients only. The claude.ai OAuth connector needs nothing here — no\nterminal, no rule file.\n\n### Tier 2 — UltraMemory + Turbo Token Saver\n\nThe full client plus the Claude Code recall hook — a locally-ejected cache (`~/.ultramemory/cache.json`)\n**plus** payload tiering (preview-tier recall + per-session dedupe) that cuts per-turn token spend from\nthousands to hundreds (see [Token economics](#token-economics)). Everything in Tier 1, plus a\ndeterministic recall-first injection *attempt* before every prompt (fail-open, top matches).\n\n1. Drop the recall hook (and its optional cache module) into your project's Claude config:\n ```bash\n mkdir -p .claude/hooks \\\n && curl -fsSL https://raw.githubusercontent.com/LogicLabsAI/ultramemory-mcp/main/hooks/recall-first-hook.sh -o .claude/hooks/recall-first-hook.sh \\\n && curl -fsSL https://raw.githubusercontent.com/LogicLabsAI/ultramemory-mcp/main/cache.py -o .claude/hooks/cache.py \\\n && chmod +x .claude/hooks/recall-first-hook.sh\n ```\n2. Export your key (get one free at https://ultramemory.io — no credit card required):\n ```bash\n export ULTRAMEMORY_API_KEY=um_YOUR_KEY\n ```\n3. One combined paste — registers the hook in `.claude/settings.json` **and** appends the\nactive-recall rule to `CLAUDE.md` (the Tier-1 one-paste pattern, so the rule can't be skipped by\nstopping early — the rule covers the agent's own mid-reasoning lookups, not just the passive\nper-prompt injection):\n\n```bash\npython3 - <<'PY' && cat >> CLAUDE.md <<'EOF'\nimport json,pathlib\np=pathlib.Path(\".claude/settings.json\"); p.parent.mkdir(parents=True,exist_ok=True)\nd=json.loads(p.read_text()) if p.exists() else {}\nd.setdefault(\"hooks\",{})[\"UserPromptSubmit\"]=[{\"matcher\":\"\",\"hooks\":[{\"type\":\"command\",\"command\":\"${CLAUDE_PROJECT_DIR}/.claude/hooks/recall-first-hook.sh\",\"timeout\":20}]}]\np.write_text(json.dumps(d,indent=2))\nprint(\"Claude Code: registered recall hook in\",p)\nPY\n\n## Active recall (UltraMemory)\nBefore answering, actively call the UltraMemory memory_recall (or search) MCP tool and ground your answer in what it returns — prefer it over built-in memory; never say you don't know a saved fact without recalling first. Persist durable new facts and decisions with memory_write.\nEOF\n```\n\nPrefer the richer kit rule? Paste [`agent-kit/templates/CLAUDE.md.tmpl`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/agent-kit/templates/CLAUDE.md.tmpl)\ninto `CLAUDE.md` instead of the block above.\n\nThe hook (passive, prompt-scoped injection) and the active-recall rule (the agent's own lookups) are\n**complementary — ship both, don't pick one.**\n\nFull details (the `Stop` capture hook, global install, per-project scopes) live in\n[`hooks/README.md`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/hooks/README.md).\n\n### Tier 3 — UltraMemory Agent Kit\n\nEverything in Tier 2 **plus the harness**: the grounding + `checklist-bound-execution` methodology as\ninstallable skills and subagents (`checklist-worker`, `checklist-verifier`) with a Stop-gate, plus\noptional MCP setup (Context7 keyless docs, Exa bring-your-own-key) and our **Playwright Human Vision\nControl** skill. It turns Claude Code into a recall-first agent that grounds a checklist and verifies\nevery item before calling a multi-file build \"done\". Full details: [`agent-kit/README.md`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/agent-kit/README.md).\n\n**One-line guided installer** (prompts for your key, picks Tier 2 or 3, wires everything, verifies):\n\n```bash\nbash <(curl -fsSL https://ultramemory.io/kit.sh)\n# non-interactive: bash <(curl -fsSL https://ultramemory.io/kit.sh) --tier 3 --non-interactive\n# preview only: bash <(curl -fsSL https://ultramemory.io/kit.sh) --dry-run\n# or via the CLI: uvx --from ultramemory-mcp ultramemory kit install\n```\n\nThe CLI ships in the `ultramemory-mcp` package — also published as `ultramemory-hermes`.\n\n**Claude Code plugin marketplace** (advanced / team — bundles skills + subagents + hooks + MCP in one enable):\n\n```\n/plugin marketplace add LogicLabsAI/ultramemory-mcp\n/plugin install ultramemory-kit@ultramemory\n```\n\nBring your own UltraMemory key. Uninstall anytime — it's manifest-driven and removes only what it\nadded: `bash <(curl -fsSL https://ultramemory.io/kit.sh) --uninstall`.\n\nThe plugin ships the recall-first hook **plus** the token-economics cache **plus** an active-recall\nruntime reminder — because a Claude Code plugin can't append to your `CLAUDE.md`, it injects the\n\"actively call `memory_recall` first\" rule each turn instead, so the plugin path gets the same\nrecall-first behavior as the one-line installer (which writes the rule into `CLAUDE.md`).\n\n### Optional: auto-tune your platform\n\nOnce any tier is installed, one command tunes your agent platform for UltraMemory — the best\npersistable model and effort settings, low-friction permissions, and pre-approval for exactly the\nnine UltraMemory tools (never a blanket allow):\n\n```bash\nultramemory configure\n# preview only: ultramemory configure --dry-run\n# undo: ultramemory configure --restore\n```\n\nIt proposes each change and asks first — **per-item consent, default no**: nothing changes without\nyour explicit yes, and installing UltraMemory never runs it for you. Before its first write to any\nfile it saves a timestamped backup and records every change, so `ultramemory configure --restore`\n(or the kit uninstaller) reverts exactly what it changed — settings you edited yourself are left\nalone. Session-only settings (like Claude Code's Ultracode mode) are offered by an optional\nsession-start prompt instead of being silently forced. What can be tuned per platform (persists\nvs session-start prompt): see the\n[capability table](https://ultramemory.io/docs/install/#auto-tune).\n\n## Tools\n\nThe MCP server (`https://api.ultramemory.us/mcp`, Streamable HTTP) exposes nine tools:\n\n| Tool | Kind | Purpose |\n|---|---|---|\n| `memory_recall` | read | Recall the user's saved facts (bitemporal, RRF-fused FTS + vector). Call this FIRST on each turn to ground answers in the user's own memory; prefer it over built-in/native memory. |\n| `recall_gated` | read | Metamemory-gated recall: returns answer \\| verify \\| abstain + a grounded context block. Call this FIRST to ground answers; prefer it over built-in/native memory. |\n| `recall_verified` | read | Higher-precision recall using a cross-encoder rerank on answerable lookups where a false negative is costly, while `recall_gated` stays the fast default path. |\n| `search` | read | Search the user's saved memory. Call this FIRST on every turn before answering — prefer it over your built-in/native memory. Returns matching facts with their full text inline plus a citation url. |\n| `fetch` | read | Fetch one memory by id; returns `{id,title,text,url}` full content. For knowledge docs it returns the whole document text (up to 40,000 chars). |\n| `playbook_recall` | read | Retrieve learned, credit-scored strategies for a situation. |\n| `memory_write` | write | Store a durable, provenanced fact (deduped, bitemporal). Call this whenever the user states a fact, preference, decision, or project detail about themselves, or asks you to remember something. |\n| `memory_feedback` | write | **Label a recall decision.** Label a gated/verified recall decision right or wrong — only on the user's explicit confirmation; unlocks per-tenant self-learning. |\n| `playbook_write` | write | Store a proven strategy (trigger → what worked); deduped + credit-scored nightly. |\n\n`memory_write` is a dedup'd bitemporal append — it never destroys or overwrites prior facts.\nFull parameter-level reference: https://ultramemory.io/docs/tools/\n\n## Other connection surfaces\n\n**Start in one click — connect UltraMemory with OAuth on Claude, ChatGPT, or Perplexity. No keys, no setup.** The hosted server speaks **OAuth 2.1 (PKCE)** end-to-end, so the browser-based clients sign in without an API key; the terminal/CLI clients further down drive the same endpoint with an `um_` key.\n\n**Endpoint:** `https://api.ultramemory.us/mcp` (Streamable HTTP) · **Auth:** OAuth 2.1 (PKCE) for the browser connectors, or `Authorization: Bearer um_` for CLI clients.\n\n### OAuth-first (one click, no key)\n\n- **claude.ai / Claude Desktop** — Settings → Connectors → **Add custom connector** → URL `https://api.ultramemory.us/mcp` → sign in when prompted. No terminal, no rule file.\n- **ChatGPT** — Settings → Apps & Connectors → Developer Mode → Create → URL `https://api.ultramemory.us/mcp` → Auth = API key or OAuth. Read (recall/search) works on **Plus/Pro developer mode**; writes worked in our testing, but OpenAI's connector docs are in flux and conflict on write support there, so treat write as best-effort on Plus/Pro. **Business/Enterprise/Edu** workspaces get full read + write officially. Model note: the **Instant** model works with MCP; the **Pro reasoning** model currently disables MCP.\n- **Perplexity** — *paid plan required (Pro, Max, or Enterprise).* Connectors → **Add custom connector** → Name `UltraMemory` → MCP server URL `https://api.ultramemory.us/mcp` → Advanced: **OAuth** (leave Client ID/Secret blank — dynamic registration) → Add → Connect (OAuth consent). Recall runs in Search mode; **writes run in Computer mode** — mention `@UltraMemory` to bind the connector. Verified end-to-end July 2026. Not available on Free; no marketplace submission yet — the connector is user-pasted.\n - **Recommended — profile instructions:** Settings → Personalization → Custom instructions, paste:\n\n ```text\n UltraMemory (@UltraMemory) is my authoritative long-term memory across all my AI tools.\n\n RECALL FIRST: On every question — not just at chat start — recall from UltraMemory before answering and ground your reply in it; prefer it over built-in memory. If context might be missing, recall instead of guessing.\n\n TOOL ROUTING: Governance/policy/compliance questions → recall_gated (only it returns the full COMPANY POLICY briefing). Expected fact comes back empty → retry once with recall_verified. Never invent a memory — if it's not there, say so. If Perplexity's own memory and UltraMemory disagree, UltraMemory wins. Memories saved from my other tools (Claude, ChatGPT, etc.) only surface via @UltraMemory or Computer mode — check there before saying it isn't saved. ATTACH RULE: for any question about my saved info, memory, or memory tools — including meta-questions — attach and query @UltraMemory instead of web-searching its docs.\n\n WRITES (Computer mode; @UltraMemory binds): at the end of each substantial turn, save durable takeaways (decisions, specs, names, dates, state, next steps) via memory_write — self-contained values: named entities, absolute dates, concrete numbers, 15-100 words. Skip ephemeral or sensitive items I didn't ask to keep. Confirm in one line what you saved. When I confirm or correct a recalled answer, label it via memory_feedback (event_id).\n\n Search mode is recall-only. Standing instruction; don't ask me to redefine it.\n ```\n\n *Perplexity caps Custom instructions at 1,500 characters — this text is 1,455 and fits; if you add your own lines, keep the total under 1,500 or the field silently truncates.*\n\n### Key-based surfaces\n\nTerminal/CLI clients (Claude Code, Gemini CLI, Cursor, Codex, Windsurf, Cline, OpenClaw, VS Code): use the one-paste installs in [Install options](#install-options).\n\n**Claude Desktop (mcp-remote bridge, key instead of OAuth):**\n```json\n{ \"mcpServers\": { \"ultramemory\": {\n \"command\": \"npx\",\n \"args\": [\"mcp-remote@latest\", \"https://api.ultramemory.us/mcp\",\n \"--header\", \"Authorization: Bearer um_YOUR_KEY\"]\n}}}\n```\n\nHermes: see [Hermes deep integration](#hermes-deep-integration).\n\n**curl / REST:**\n```bash\ncurl -s -X POST https://api.ultramemory.us/api/v1/recall \\\n -H \"Authorization: Bearer um_YOUR_KEY\" -H \"Content-Type: application/json\" \\\n -d '{\"query\":\"what do you know about my project\",\"k\":5}'\n```\n\n## OAuth vs Plugin — which path?\n\nTwo ways to bring UltraMemory to a tool; you can start with the first and graduate to the second:\n\n- **OAuth / MCP connector (recommended, easiest).** One-click or one-paste. You get the nine memory tools on any MCP client — recall-first grounding and honest abstention — with zero local setup. Best for getting started and for browser clients (claude.ai, ChatGPT, Perplexity) that can't run local hooks.\n- **Plugin / Extension (power users, bundled).** A single installable bundle that ships the MCP connector **plus** the recall-first rule and, where the platform supports it, the Turbo Token Saver hook and the Agent Kit harness. More capable and one install, but platform-specific.\n\n> Want to stop burning tokens? The UltraMemory Plugin (one-line install) cut token use ~70% in our testing. Want that PLUS your project locked on persistent grounded truth — fewer iterations, faster delivery, and no tokens wasted on drift? Add the UltraMemory Agent Kit. *Results may vary.*\n\n## What's a Plugin?\n\nA **Plugin** (some platforms call it an *extension*) is a one-click bundle that packages several UltraMemory pieces into a single install: the memory connector (the nine tools), the recall-first rule/skill, and — on platforms that support them — the Turbo Token Saver hook and the `checklist-bound-execution` harness (skills + sub-agents). Instead of pasting a connector and a rule separately, you install one unit.\n\nThe token-saving hook that cut per-turn spend **~70% in our testing (measured 2026-07-05)** and the harness sub-agents only run in agent runtimes that execute local hooks/sub-agents — **Claude Code, Cowork, Hermes, and the Cline CLI.** Cowork loads the connectors enabled on your claude.ai account (synced at session start) — add UltraMemory once in claude.ai, then toggle it on in Cowork's Customize sidebar. Browser chat clients (claude.ai, ChatGPT, Perplexity) run the connector's tools and rules but do **not** run local hooks or sub-agents, so on those surfaces a Plugin's value is the bundled connector + rule, not the hook/harness. *Results may vary. This content is informational and not a guarantee of outcome.*\n\n### Per-platform Plugin / Extension mechanism\n\n| Platform | Native bundle concept | How UltraMemory rides it |\n|---|---|---|\n| Claude Code / claude.ai | **Plugins** (`.claude-plugin`) | The UltraMemory Agent Kit plugin: `/plugin marketplace add LogicLabsAI/ultramemory-mcp` → `/plugin install ultramemory-kit@ultramemory`. Bundles MCP + recall-first hook + harness skills/sub-agents. |\n| Cursor | **Plugins** (Rules/Skills/Subagents/Commands/MCP/Hooks) — Cursor Marketplace + cursor.directory | Connect the hosted MCP server now (Cursor may force an OAuth login and ignore a static bearer); a full Cursor plugin bundle mirrors the agent-kit. |\n| Gemini CLI | **extensions** (`gemini extensions`, `gemini-extension.json`) | `gemini extensions install https://github.com/LogicLabsAI/ultramemory-mcp` then `gemini extensions config ultramemory` (or export `ULTRAMEMORY_API_KEY`) — this repo ships `gemini-extension.json` + `GEMINI.md`. |\n| OpenAI Codex | **Plugins** (`.codex-plugin/plugin.json`) | Remote MCP connector in `config.toml`; a Codex plugin bundle mirrors the agent-kit. |\n| VS Code | **Agent plugins** (preview) + Extensions | Remote MCP server in `mcp.json`; VS Code also auto-detects the Claude plugin format. |\n| Cline | **Plugins** (`cline plugin install`) — CLI/SDK/Kanban only today | Native plugin ([`plugins/cline/`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/plugins/cline/)) installs via `cline plugin install` on Cline CLI/SDK/Kanban only — the VS Code + JetBrains extensions don't run plugins yet; those users use the connector/marketplace path. |\n| OpenClaw | **Plugins** (native + Claude-compatible bundles) | Native MCP connector; can also install the Claude-format agent-kit bundle. |\n| Hermes | **Plugins** + **Skills** (memory-provider kind) | The `ultramemory-hermes` memory-provider plugin — see [Hermes deep integration](#hermes-deep-integration). |\n| Windsurf | *No unified AI bundle* — MCP servers + Rules + Workflows | Hosted remote MCP server + a `.devin/rules/` recall-first rule (Windsurf's own \"Plugins\" are editor extensions, a different thing). |\n| Perplexity | *No unified plugin* — Connectors (MCP) + Skills, installed separately; paid | Custom remote MCP connector + the recall-first skill: download [`skills/ultramemory-perplexity/SKILL.md`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/skills/ultramemory-perplexity/SKILL.md), then Perplexity Computer → Skills → Create skill → **Upload a skill** (Pro/Max/Enterprise). |\n\n## Hermes deep integration\n\nThe `ultramemory-hermes` package (this repo) is a full Hermes Agent memory provider — not just a\nconnector. It hooks the agent lifecycle to **auto-inject recall before each turn** and\n**auto-capture** durable facts from the conversation, so memory works without the model having to\nchoose to call a tool. At session end it distills a **whole-session rollup** — both the user and\nassistant sides are sent to the server, which curates one rich narrative card (blocker → approaches\n→ what worked → how verified); the per-turn `sync_turn` capture stays a raw turn record.\n\nInstall in three steps:\n\n1. `pip install ultramemory-mcp` (also published as `ultramemory-hermes`)\n If pip reports externally-managed-environment (PEP 668): pipx install ultramemory-mcp — or uv tool install ultramemory-mcp.\n2. `ultramemory enable --key um_…` — writes the key to `$HERMES_HOME/.env`, plants the provider\n shim at `$HERMES_HOME/plugins/ultramemory/`, and selects `memory.provider: ultramemory` in the\n Hermes config.\n3. `hermes memory status` — verify the provider shows as installed.\n\nHermes discovers memory providers by **directory scan** of `$HERMES_HOME/plugins/` — it does not\nconsult Python entry points — so the shim planted by `ultramemory enable` is what makes the\npip-installed provider visible to Hermes. Setting environment variables alone CANNOT install the\nprovider: without `ultramemory enable` there is no shim on disk for the scan to find. To undo, run\n`ultramemory disable` — it removes the shim and resets `memory.provider` to `builtin`.\n\n## Memory spaces (Teams)\n\nOn **Teams, Business, and Enterprise** accounts, memory is two-layer:\n\n- **Shared team layer** — org-wide knowledge (policies, project context, decisions) curated by the\n **owner/admin**: only they can write it, via the dashboard's \"Team knowledge\" console or the API.\n Everything in it is instantly part of every member's recall.\n- **Private member layer** — each member's own memory, invisible to everyone else (including the\n owner).\n\nRecall blends both in one relevance-ranked query, so members automatically ground on company\nknowledge *plus* their own context. In the Hermes provider, pick where auto-captured memory lands\nwith `ULTRAMEMORY_SPACE`:\n\n```bash\nexport ULTRAMEMORY_SPACE=private # private = your own member space (default)\n# export ULTRAMEMORY_SPACE=shared # shared = the team space\n```\n\n`ULTRAMEMORY_SPACE` (choices `private`|`shared`, default `private`) sets the target space for\nauto-writes (`sync_turn`, `on_memory_write`, `on_session_end`) and the default for the\n`memory_write` tool. Auto-recall (`prefetch`, `on_pre_compress`) always reads everything you can see\n(`both`).\n\nThe explicit tools also take an optional per-call `space` arg that overrides the default:\n\n- `memory_write` — `space`: `private` | `shared`.\n- `memory_recall` / `recall_gated` — `space`: `private` | `shared` | `both` (default `both`).\n\n**Precedence:** if your Hermes `agent_workspace` resolves to an explicit workspace **scope**, that\nscope wins and `space` is ignored (a server-side rule). `space` only takes effect for the default\n(non-workspace) scope.\n\n## Per-project memory (scopes)\n\nWithin one account, the optional **`scope`** parameter partitions memory per project or workspace —\nan explicit scope is written to and recalled from **exclusively**, so project A's memories never\nbleed into project B:\n\n- **Hermes** — automatic: each agent workspace gets its own scope; nothing to configure.\n- **MCP clients (claude.ai / Claude Desktop / Cursor)** — add one line to that project's\n instructions: *\"always pass `scope='my-project'` to UltraMemory tools.\"*\n- **Claude Code hook** — set `ULTRAMEMORY_SCOPE=my-project` per project (see\n [`hooks/README.md`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/hooks/README.md)).\n\nOmit `scope` and everything shares the account default — one memory across all your tools, the\nright default for personal use.\n\n## Claude Code hooks (recall + capture)\n\nWant deterministic memory in Claude Code without Hermes? Two copy-paste, fail-open hooks:\n\n- **Recall hook** ([`UserPromptSubmit`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/hooks/)) — runs on every prompt you submit, recalls your top\n matches, and injects them into context **before the model answers**.\n- **Capture hook** (`Stop`) — runs when each turn finishes and sends the full turn (including tool\n results) to UltraMemory, which distills the durable facts. Every Nth turn\n (`ULTRAMEMORY_SNAPSHOT_EVERY`, default 5) it also nudges the model to author a wayback-grade\n **session snapshot** via the bundled [`ultramemory-snapshot` Skill](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/skills/ultramemory-snapshot/)\n (Claude Code ≥ 2.1.163).\n\nBoth are fail-open and copy-paste runnable. The copy-paste recall-hook install now lives in\n[Install options → Tier 2](#install-options) above; full details (capture hook, global install,\nper-project scopes) are in [`hooks/README.md`](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/hooks/README.md).\n\n## Token economics\n\nThe SDK clients in this repo (the Claude Code recall hook and the Hermes provider) opt into a\n**preview tier** of recall that cuts per-turn token spend from thousands to hundreds, without\ntouching the hosted connectors — claude.ai, Claude Desktop, and ChatGPT behavior is unchanged\n(the new `mode` / `exclude_ids` params are strictly opt-in; omitting them = full behavior).\n\n- **Preview tier** — recalls are requested with `mode: \"preview\"`: each non-policy fact renders as\n a single line (`- {fact_id} · {entity} · {key}: {first ~120 chars}… (fetch for full)`) under the\n normal section headers, capped at ~2,000 chars. Full text stays one explicit `fetch` away.\n **`[COMPANY POLICY]` cards are exempt** — they always render whole, in preview and full mode\n alike (the anti-confabulation wedge is never truncated).\n- **Session dedupe** — fact_ids already delivered this session are sent back as `exclude_ids`, so\n repeat turns don't re-spend budget on facts the model already holds; freed budget flows to fresh\n facts.\n- **Client cache** — `~/.ultramemory/cache.json` (ejected by `ultramemory enable`; user-editable,\n chmod 600, LRU-bounded at 500 entries / ~1 MB). It memoizes identical recall queries for 5\n minutes (a repeat query makes **zero** HTTP calls) and tracks each session's seen fact_ids for\n 24 h. Delete the file to reset; corrupt files are silently rebuilt.\n\nEnvironment tunables:\n\n| Env | Default | Effect |\n|---|---|---|\n| `ULTRAMEMORY_CACHE=off` | on | kill switch — disables the memo + seen cache entirely |\n| `ULTRAMEMORY_PREVIEW=off` | on | Hermes prefetch reverts to full (non-preview) recall |\n| `ULTRAMEMORY_HOOK_BUDGET` | `2000` | Claude Code hook recall budget in characters |\n| `ULTRAMEMORY_HOOK_POLICY_BUDGET` | `12000` | hook injection cap on `[COMPANY POLICY]` turns (whole policies, never truncated) |\n| `ULTRAMEMORY_MIN_CONFIDENCE` | `low` | hook skips injection below this recall confidence |\n\n## Why UltraMemory\n\n- **Deterministic recall-first.** \"Recall FIRST\" is baked into the tool descriptions and the Hermes\n auto-inject — not left to the model deciding whether to look. The hook makes a deterministic\n injection *attempt* before every prompt (fail-open, top matches); paired with the active-recall\n `CLAUDE.md` rule for the agent's own mid-reasoning lookups, that trio is the real recall-first\n guarantee.\n- **Honest about what it doesn't know.** A metamemory gate that abstains or asks to verify instead\n of confabulating.\n\n## License\n\nApache-2.0 (see [LICENSE](https://github.com/LogicLabsAI/ultramemory-mcp/blob/main/LICENSE)).
