keepsake-mcp

MCP server for Keepsake (keepsake.place), the app where creators and solo entrepreneurs empty their heads: ideas, tasks and the people who matter, together and linked in one place, all the way to publishing.

Connect your AI assistant (Claude, Cursor, or any MCP-compatible client) to your Keepsake data: contacts, interactions, tasks, notes, daily intentions, companies, and tags.

Why

Your AI assistant forgets between conversations; Keepsake remembers. Ask it to:

• "Capture this idea for my next article in #newsletter#"
• "Who did I last talk to at Acme Corp?"
• "Add a note that I ran into Sarah at the conference"
• "What tasks are overdue?"
• "Show me everything related to the #house-project tag"
• "Create a follow-up task for my meeting with John next week"

Quick start

1. Get your API key

Sign up at keepsake.place, then go to Account > API Keys to generate one.

2. Choose your connection method

Option A: Remote (HTTP) — recommended

No installation required. Works with Claude iOS, Claude web, Claude Desktop Connectors, and any MCP client that supports Streamable HTTP.

Endpoint: https://app.keepsake.place/api/mcp

Authentication: Pass your API key as a Bearer token in the Authorization header.

Claude Desktop (Connectors):

Add a remote MCP server in Claude Desktop settings with:

• URL: https://app.keepsake.place/api/mcp
• Authentication: Bearer token with your ksk_ API key

Any MCP client (Streamable HTTP):

{
  "mcpServers": {
    "keepsake": {
      "type": "streamable-http",
      "url": "https://app.keepsake.place/api/mcp",
      "headers": {
        "Authorization": "Bearer ksk_YOUR_API_KEY"
      }
    }
  }
}

Option B: Local (stdio)

Runs locally via npx. Useful for Claude Code, Cursor, and local development.

Claude Desktop:

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "keepsake": {
      "command": "npx",
      "args": ["-y", "keepsake-mcp"],
      "env": {
        "KEEPSAKE_API_KEY": "ksk_YOUR_API_KEY"
      }
    }
  }
}

Claude Code:

claude mcp add keepsake -- npx -y keepsake-mcp

Then set KEEPSAKE_API_KEY in your environment.

Cursor:

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "keepsake": {
      "command": "npx",
      "args": ["-y", "keepsake-mcp"],
      "env": {
        "KEEPSAKE_API_KEY": "ksk_YOUR_API_KEY"
      }
    }
  }
}

Server instructions

On connection, the server sends MCP instructions — injected into the client's system prompt. It is the only channel that reaches an agent before it goes looking for a capability, so it stays short and points at the rest: call get_agent_instructions for the full doctrine, and put editorial remarks in a note's margin (create_note_comment) rather than in the chat, which disappears.

QuickNotes

Note comments (marginalia)

Material kept alongside a note without entering its text — an idea, a reference, an excerpt pasted to rewrite a passage later. Anchored to a passage by quoting it, or to the whole note. Never published, and temporary by design: anything worth keeping becomes a note or a linked task.

Days (intention or question of the day)

Day blocks (Day-view timeline)

Recurring blocks (ideal day / ideal week, habits)

Tool annotations

All tools include MCP safety annotations:

• Read-only tools (list_*, get_*, search_*): marked readOnlyHint: true
• Create tools: marked destructiveHint: false
• Update tools: marked destructiveHint: false, idempotentHint: true
• Delete tools: marked destructiveHint: true, idempotentHint: true

Activity tracking

Every write operation (create, update, delete) performed through the API is recorded in an Activity Feed visible to the user inside Keepsake. Each action shows the entity type, a content preview, and which API key was used.

This means your user can see everything you do. Be transparent and precise. If you make a mistake, let the user know so they can verify in the activity feed.

Call get_agent_instructions at the start of each session for the full best practices guide.

Environment variables

Rate limits

60 requests per minute per API key. Rate limit headers are included in responses.

Privacy

Keepsake MCP server only communicates with the Keepsake API (app.keepsake.place). It does not send data to any third-party service. Your data stays between your MCP client and your Keepsake account.

All API calls are authenticated with your personal API key and scoped to your account via Row Level Security. No other user's data is accessible.
