The local full profile serves 163 tool names, 11 resources, and 10 prompts (158 canonical operations plus 5 fiscal aliases). The hosted grouped profile serves 166 tool names, 7 resources, and 10 prompts (the same names plus 3 discovery tools, with API-backed resources kept local-only). The separately reviewed OpenAI profile serves 33 tool names, 0 resources, and 0 prompts. Catalogue membership is not a promise that a backing API is enabled for every workspace.\n\n---\n\n## What is this\n\nAn MCP server that connects your AI assistant to [Frihet](https://frihet.io/?utm_source=github_readme&utm_medium=mcp_readme&utm_campaign=mcp_landgrab). Create invoices by talking. Query expenses in natural language. Manage your entire business from your IDE.\n\n```\nYou: \"Create an invoice for TechStart SL, 40 hours of consulting at 75 EUR/hour, due March 1st\"\nClaude: Done. Invoice INV-2026-089 created. Total: 3,000.00 EUR + 21% IVA = 3,630.00 EUR.\n```\n\n158 canonical operations. Five fiscal aliases. Ten prompts. The local package serves 11 resources; the hosted Worker deliberately serves the 7 static resources, while API-backed workspace resources remain local-profile only.\n\n\n\n---\n\n## Try it instantly (no signup)\n\nKick the tires with zero setup — no account, no API key:\n\n```bash\nFRIHET_DEMO=1 npx -y @frihet/mcp-server\n```\n\nIn demo mode the server answers from realistic **example fixtures** (Spanish invoices with IVA/IGIC, expenses, clients, products, a bank account, and more) — every record uses `demo_`-prefixed IDs and the server prints a `DEMO MODE` banner on startup. **Nothing is persisted** and no network call is ever made. Writes are simulated and fiscal actions (e-invoice, VeriFactu, TicketBAI, FACe, payroll) return a clearly-labeled simulation — never a real submission to any tax authority.\n\nWhen you're ready for your real data, drop the flag and add your key ([app.frihet.io](https://app.frihet.io) → Settings → API keys). See [Install](#install) below.\n\n---\n\n## For AI agents\n\nIf you are an agent reading this repository rather than a person reading a page, everything you need is machine-readable and generated from the running server — you do not have to parse this README.\n\n| What | Where |\n|------|-------|\n| Onboarding contract: quickstart per client, auth, safe workflow, human-authority tool lists, error recovery | [`docs/agent-onboarding.json`](https://github.com/Frihet-io/frihet-mcp/blob/main/docs/agent-onboarding.json) — also shipped inside the npm package |\n| Per-tool capability truth: `callability`, `writesFrihet`, `externalInteraction`, `externalSideEffects` | `_meta[\"io.frihet/capability\"]` on every entry of `tools/list` |\n| How to behave once connected | the `instructions` string returned by `initialize` — your client hands it to you automatically |\n\nThree rules the contract encodes, in short:\n\n1. **Orient before acting.** `get_business_context` and the `frihet://tax/rates` resource decide the correct fiscal treatment. Do not recall a Spanish tax rate from memory.\n2. **Draft, show, stop.** `create_invoice`, `create_quote` and `create_credit_note` all default to `status=draft` — no fiscal number, no hash, nothing sent to a tax authority. Present the draft and hand back.\n3. **Human authority is not yours to assume.** Any tool with a non-empty `externalSideEffects` reaches a client's inbox, a webhook, money, or AEAT / VeriFactu / TicketBAI / FACe. Several also take `confirm=true`; that flag records a human decision — never set it to satisfy your own plan.\n\n`docs/agent-onboarding.json` is regenerated from the live surface by `npm run generate:agent-onboarding` and gated in CI by `npm run gate:agent-onboarding`, so its tool lists and counts cannot drift from the server.\n\n---\n\n## Install\n\n### One-line (Claude Code, Cursor, Copilot, Codex, Windsurf, Gemini CLI, and more)\n\n```bash\nnpx skills add Frihet-io/frihet-mcp\n```\n\n### Claude Code plugin (skill + MCP server in one install)\n\nThis repository is also a Claude Code plugin (`frihet-erp`): installing it wires up both the business-management skill and the MCP server.\n\n```bash\n# Try it locally\nclaude --plugin-dir /path/to/frihet-mcp\n```\n\nOnce available in the community marketplace:\n\n```text\n/plugin marketplace add anthropics/claude-plugins-community\n/plugin install frihet-erp@claude-community\n```\n\nSkill invocation: `/frihet-erp:frihet-mcp`. The bundled `.mcp.json` launches `@frihet/mcp-server` via `npx` — set `FRIHET_API_KEY` in your environment (get one at [app.frihet.io](https://app.frihet.io) → Settings → API keys).\n\n### Claude Code — one command\n\n```bash\nclaude mcp add frihet -s user -e FRIHET_API_KEY=fri_your_key_here -- npx -y @frihet/mcp-server\nclaude mcp list # verify: frihet ✓ Connected\n```\n\nThe CLI owns the config file, so there is nothing to hand-edit and no path to get wrong. (User scope writes `~/.claude.json`, not `~/.claude/mcp.json`.)\n\n### Codex CLI — one command\n\n```bash\ncodex mcp add frihet --env FRIHET_API_KEY=fri_your_key_here -- npx -y @frihet/mcp-server\ncodex mcp list # verify\n```\n\nCodex config is **TOML**, not JSON. `codex mcp add` writes:\n\n```toml\n[mcp_servers.frihet]\ncommand = \"npx\"\nargs = [\"-y\", \"@frihet/mcp-server\"]\n\n[mcp_servers.frihet.env]\nFRIHET_API_KEY = \"fri_your_key_here\"\n```\n\n> Pasting a JSON `mcpServers` block into `~/.codex/config.toml` is a TOML parse error that takes down your **whole** Codex config, not just this server. Use the command above.\n\n### Claude Desktop, Cursor, Windsurf, Cline — JSON config\n\n```json\n{\n \"mcpServers\": {\n \"frihet\": {\n \"command\": \"npx\",\n \"args\": [\"-y\", \"@frihet/mcp-server\"],\n \"env\": {\n \"FRIHET_API_KEY\": \"fri_your_key_here\"\n }\n }\n }\n}\n```\n\n| Tool | Config file |\n|------|------------|\n| Claude Desktop | `~/Library/Application Support/Claude/claude_desktop_config.json` |\n| Cursor | `.cursor/mcp.json` or `~/.cursor/mcp.json` |\n| Windsurf | `~/.windsurf/mcp.json` |\n| Cline | VS Code settings or `.cline/mcp.json` |\n\nThe JSON above is identical for these four clients; only the file path changes. Claude Code and Codex are **not** in this table — they manage their own config through the CLI commands shown above.\n\n### Remote (no install)\n\nUse the hosted endpoint at `mcp.frihet.io` -- zero local dependencies, runs on Cloudflare Workers.\n\n**With API key:**\n\n```json\n{\n \"mcpServers\": {\n \"frihet\": {\n \"type\": \"streamable-http\",\n \"url\": \"https://mcp.frihet.io/mcp\",\n \"headers\": {\n \"Authorization\": \"Bearer fri_your_key_here\"\n }\n }\n }\n}\n```\n\n**With OAuth 2.0 + PKCE** (browser-based login, no API key needed):\n\nClients that support OAuth (Claude Desktop, Smithery, etc.) can connect directly to `https://mcp.frihet.io/mcp` and authenticate via browser. The server implements the full OAuth 2.1 authorization code flow with PKCE.\n\n### Get your API key\n\n1. Log into [app.frihet.io](https://app.frihet.io)\n2. Go to **Settings > API**\n3. Click **Create API key**\n4. Copy the key (starts with `fri_`) -- it's only shown once\n\n---\n\n## What you can do\n\nTalk to your ERP. These are real prompts, not marketing copy.\n\n### Invoicing\n\n```\n\"Show me all unpaid invoices\"\n\"Create an invoice for Acme SL with 10h of consulting at 95/hour\"\n\"Mark invoice abc123 as paid\"\n\"How much has ClientName been invoiced this year?\"\n```\n\n### Expenses\n\n```\n\"Log a 59.99 EUR expense for Adobe Creative Cloud, category: software, tax-deductible\"\n\"List all expenses from January\"\n\"What did I spend on travel last quarter?\"\n```\n\n### Clients\n\n```\n\"Add a new client: TechStart SL, NIF B12345678, email admin@techstart.es\"\n\"Show me all my clients\"\n\"Update ClientName's address to Calle Mayor 1, Madrid 28001\"\n```\n\n### CRM\n\n```\n\"Add a contact to Acme SL: Ana Garcia, CTO, ana@acme.es\"\n\"Log a call with TechStart: discussed Q2 proposal, they're interested in upgrade\"\n\"Add a note to ClientName: prefers invoices in English, payment NET 30\"\n\"Show me all activities for Acme SL\"\n```\n\n### Quotes\n\n```\n\"Create a quote for Design Studio: logo design (2000 EUR) + brand guidelines (3500 EUR)\"\n\"Show me all pending quotes\"\n```\n\n### Webhooks\n\n```\n\"Set up a webhook to notify https://my-app.com/hook when invoices are paid\"\n\"List all my active webhooks\"\n```\n\n---\n\n## What to expect\n\nThis MCP is a **structured data interface** -- you describe what you want in natural language, and the AI creates, queries, or modifies business records in Frihet. Most of the 158 canonical operations are CRUD operations over the REST API; the rest are read-only summaries and fiscal/e-invoice actions. Alias and discovery names are counted separately.\n\n**Works great:**\n\n```\n\"Create an invoice for TechStart SL, 40h consulting at 75 EUR/h\" --> creates the invoice\n\"Show unpaid invoices over 1,000 EUR\" --> queries and filters\n\"Log a 120 EUR expense for the Madrid train, category: travel\" --> records the expense\n\"Update client Acme's email to billing@acme.es\" --> modifies the record\n```\n\n**Does not do:**\n\n- OCR or PDF scanning -- you cannot upload an invoice image and have it read\n- File upload or attachment handling\n- Image processing of any kind\n\nIf you need to digitize paper invoices or receipts, extract the data first (e.g., Claude Vision API, a dedicated OCR service, or manual entry), then use the MCP to create the record:\n\n```\n1. Scan/photograph the invoice\n2. Use Claude Vision: \"Read this invoice image and extract the vendor, items, amounts, and dates\"\n3. Then: \"Create an expense in Frihet for [extracted data]\"\n```\n\n---\n\n## Catalogue operations (158)\n\n### Invoices (12)\n\n| Tool | What it does |\n|------|-------------|\n| `list_invoices` | List invoices with pagination |\n| `get_invoice` | Get full invoice details by ID |\n| `create_invoice` | Create a new invoice with line items |\n| `update_invoice` | Update any invoice field |\n| `delete_invoice` | Delete a draft invoice;

List response shapes follow their API family; not every list endpoint is paginated.\n\n### Capability and side-effect truth\n\nOn the full MCP surfaces, every `tools/list` entry includes `_meta[\"io.frihet/capability\"]`:\n\n- `registered` means the name and handler exist in this server build;\n- `callability` is `api_dependent` (the handler calls the API; deployment, workspace enablement, and authorization still decide), `runtime_checked` (the handler explicitly distinguishes an absent backend from empty data), `deferred`, `unavailable`, or `local`—never an unconditional “available” claim;\n- `writesFrihet`, `externalInteraction`, and `externalSideEffects` distinguish state changes and calls to external entities/providers;\n- MCP action annotations remain the standard source for read-only, destructive, idempotent, and open-world hints.\n\nThe ChatGPT/OpenAI host is a separately reviewed surface: exactly 33 business operations with complete descriptions, 0 discovery meta-tools, 0 prompts, and 0 resources. Its 17 reads and 16 writes are deliberately narrow, and all writes require literal `confirm=true`. Ten writes may deliver full business events to active endpoints previously configured by the workspace owner; webhook administration itself remains excluded. Direct email delivery, the legacy monthly summary, raw invoice PDFs, invoice lifecycle transitions, updating an existing quote, regulated filing, deleting client parent records, deleting expenses with their linked files, deleting products, and deleting vendors are also excluded. This surface must not be inferred from the full catalogue.\n\n---\n\n## Resources\n\nContext the AI can read to make smarter decisions.\n\nThe local package serves 11 resources: 7 static references plus 4 API-backed workspace resources. The hosted Worker serves the 7 static resources. The OpenAI-reviewed host serves 0 resources.\n\n**Static** (reference data, no API calls):\n\n| Resource | URI | What it provides |\n|----------|-----|-----------------|\n| API Schema | `frihet://api/schema` | OpenAPI summary: endpoints, auth, rate limits, pagination, error codes |\n| Tax Rates | `frihet://tax/rates` | Tax rates by Spanish fiscal zone: IVA, IGIC, IPSI, EU reverse charge, IRPF |\n| Tax Calendar | `frihet://tax/calendar` | Quarterly and annual filing deadlines for the listed Spanish tax models |\n| Expense Categories | `frihet://config/expense-categories` | 8 categories with deductibility rules, IVA treatment, amortization |\n| Invoice Statuses | `frihet://config/invoice-statuses` | Status flow (draft > sent > paid/overdue > cancelled), transition rules, webhook events |\n| Currencies | `frihet://config/currencies` | 40 supported currencies with ISO codes, symbols, decimal places, locale formatting |\n| Countries | `frihet://config/countries` | 61 supported countries with fiscal zones, default tax rates, currencies, invoice prefixes |\n\n**Dynamic** (live data from your account):\n\n| Resource | URI | What it provides |\n|----------|-----|-----------------|\n| Business Profile | `frihet://business-profile` | Your business info, plan, defaults, recent activity, top clients |\n| Monthly Snapshot | `frihet://monthly-snapshot` | Current month P&L, revenue, expenses, tax liability |\n| Overdue Invoices | `frihet://overdue-invoices` | All invoices past due date (up to 100) |\n| Plan Limits | `frihet://status/plan-limits` | Live plan tier, usage counters, invoices/month, API rate limits |\n\n---\n\n## Prompts (10)\n\nPre-built workflows the AI can execute as guided multi-step operations.\n\n| Prompt | What it does | Arguments |\n|--------|-------------|-----------|\n| `monthly-close` | Close the month: review unpaid invoices, categorize expenses, check tax obligations, generate summary | `month?` (YYYY-MM) |\n| `onboard-client` | Set up a new client with correct tax rates by location, optionally create a welcome quote | `clientName`, `country?`, `region?` |\n| `quarterly-tax-prep` | Prepare quarterly tax filing: calculate IVA/IGIC, identify deductibles, preview Modelo 303/130/420 | `quarter?`, `fiscalZone?` |\n| `overdue-followup` | Find overdue invoices, draft follow-up messages, suggest payment reminders | -- |\n| `new-client-invoice` | Create a client + first invoice in one workflow with tax rate lookup | `clientName`, `country?` |\n| `expense-report` | Generate expense report grouped by category with deductible totals | `month?` (YYYY-MM) |\n| `year-end-close` | Full annual closing: quarterly review, pending invoices, uncategorized expenses, year-end checklist | `year` (YYYY) |\n| `cash-flow-forecast` | Project cash flow for coming months: recurring income, expenses, overdue receivables, tax deadlines | `months?` (default: 3) |\n| `invoice-aging-review` | AR aging analysis: group unpaid invoices by bucket (0-30/31-60/61-90/90+ days), top debtors, collection actions | -- |\n| `expense-batch` | Process expenses in bulk: categorize, apply tax rates, flag missing receipts | `fiscalZone?` |\n\n---\n\n## How it works\n\n```mermaid\ngraph LR\n AI[\"Your AI assistant\"]\n MCP[\"frihet-mcp\"]\n API[\"api.frihet.io\"]\n DB[\"Frihet ERP\"]\n\n AI -- \"create_invoice()\" --> MCP\n MCP -- \"POST /v1/invoices\" --> API\n API --> DB\n DB -- \"201 + invoice data\" --> API\n API -- \"structured JSON\" --> MCP\n MCP -- \"typed response + suggestions\" --> AI\n\n style AI fill:#09090b,stroke:#4ade80,color:#fafafa\n style MCP fill:#09090b,stroke:#fafafa,color:#fafafa\n style API fill:#09090b,stroke:#3f3f46,color:#a1a1aa\n style DB fill:#09090b,stroke:#3f3f46,color:#a1a1aa\n```\n\nThe server translates tool calls into REST API requests. It handles authentication, rate limiting (automatic retry with backoff on 429), pagination, and error mapping.\n\nTwo transports:\n- **stdio** (local) -- `npx @frihet/mcp-server` with `FRIHET_API_KEY`\n- **Streamable HTTP** (remote) -- `https://mcp.frihet.io/mcp` with Bearer token or OAuth 2.0+PKCE\n\n### Environment variables\n\n| Variable | Required | Default |\n|----------|----------|---------|\n| `FRIHET_API_KEY` | Yes (stdio) | -- |\n| `FRIHET_API_URL` | No | `https://api.frihet.io/v1` |\n| `FRIHET_TOOL_MODE` | No | `full` |\n\n---\n\n## Tool exposure: depth served on demand\n\nFrihet's differentiator is **depth** — full ES/EU fiscal coverage plus native compliance (VeriFactu, TicketBAI, Facturae/FACe; KSeF Poland infra-ready, activation pending), banking, CRM, HR/payroll, stay/PMS and POS. But a flat list of every tool, loaded into an agent's context up front, is the 2026 context-rot problem: it crowds out the task and degrades tool selection before any work begins.\n\n`FRIHET_TOOL_MODE` lets you choose how that depth is exposed.\n\n| Mode | Behavior |\n|------|----------|\n| `full` (default) | Canonical tools and fiscal aliases are exposed with full descriptions and schemas. Public descriptors add conservative callability and side-effect truth; operation names, schemas and handlers are unchanged. |\n| `grouped` | **Progressive disclosure.** Each tool's description collapses to a one-line `[group] summary — full schema via describe_tool('name')`, and three lightweight discovery tools are added. The agent loads depth only for the tools it actually needs. |\n\nIn `grouped` mode operation names, input schemas and handlers are unchanged. Descriptors also expose the same conservative capability and action truth as the full profile. Discovery flows through three meta-tools:\n\n- **`list_tool_groups()`** — the domain map (invoicing, expenses, fiscal/compliance, banking, CRM, HR/payroll, stay/PMS, POS, intelligence, products, platform) with a one-line blurb and tool count for each.\n- **`search_tools(query)`** — free-text search across tool name, title, summary and group; returns matching tools with their group, summary, read-only flag and input fields. Optional `group` filter and `limit`.\n- **`describe_tool(name)`** — the full original description and input fields for one tool, on demand, before you call it.\n\n```jsonc\n// claude_desktop_config.json — opt in to grouped mode\n{\n \"mcpServers\": {\n \"frihet\": {\n \"command\": \"npx\",\n \"args\": [\"@frihet/mcp-server\"],\n \"env\": {\n \"FRIHET_API_KEY\": \"fri_...\",\n \"FRIHET_TOOL_MODE\": \"grouped\"\n }\n }\n }\n}\n```\n\n> Grouped exposure changes description density, not operation behavior. The versioned OpenAI-reviewed profile is composed separately and remains independently gated.\n\n---\n\n## API limits\n\n| Limit | Value |\n|-------|-------|\n| Requests per minute | 100 per API key |\n| Results per page | 100 max (50 default) |\n| Request body | 1 MB max |\n| Webhook payload | 100 KB max |\n| Webhooks per account | 20 max |\n\nRate limiting is handled automatically with exponential backoff.\n\n---\n\n## Claude Code Skill\n\nBeyond raw MCP tools, this repo includes a **Claude Code skill** that adds business context: Spanish tax rules, workflow recipes, financial reports, and natural language commands.\n\n### Install the skill\n\n```bash\ngit clone https://github.com/Frihet-io/frihet-mcp.git\nln -s \"$(pwd)/frihet-mcp/skill\" ~/.claude/skills/frihet\n```\n\nOr with the universal installer:\n\n```bash\nnpx skills add Frihet-io/frihet-mcp\n```\n\n### Commands\n\n| Command | What it does |\n|---------|-------------|\n| `/frihet status` | Account overview, recent activity, pending payments |\n| `/frihet invoice` | Create, list, search invoices |\n| `/frihet expense` | Log and query expenses |\n| `/frihet clients` | Manage client database |\n| `/frihet quote` | Create and manage quotes |\n| `/frihet report` | Financial summaries (P&L, quarterly, overdue) |\n| `/frihet webhooks` | Configure automation triggers |\n| `/frihet setup` | Guided setup and connection test |\n\nThe skill knows about IVA rates, IRPF retention, Modelo 303 prep, expense deductibility rules, and VeriFactu compliance.\n\nFull documentation: [docs.frihet.io/desarrolladores/skill-claude-code](https://docs.frihet.io/desarrolladores/skill-claude-code)\n\n---\n\n## Development\n\n```bash\ngit clone https://github.com/Frihet-io/frihet-mcp.git\ncd frihet-mcp\nnpm install\nnpm run build\n```\n\nRun locally:\n\n```bash\nFRIHET_API_KEY=fri_xxx node dist/index.js\n```\n\nTest with the [MCP Inspector](https://modelcontextprotocol.io/docs/tools/inspector):\n\n```bash\nnpx @modelcontextprotocol/inspector node dist/index.js\n```\n\n---\n\n## Contributing\n\nContributions are welcome.
