knowmind

Persistent memory for your AI tools. Store something once, and it is available in Claude Code, Cursor, and any other MCP client that runs a local (stdio) server — as a typed knowledge graph with provenance, confidence, and a bitemporal history for every fact. Hosted in Germany (Hetzner, Nuremberg data center); the CLI and MCP server in this repository are Apache-2.0.

The free tier is permanently free and requires no payment details. The API, CLI, and MCP server are included in every tier.

Connect your AI tool in three steps

1. Create a free account at knowmind.de and generate an access token: Dashboard → API tokens.
2. Store the token locally:

npx -y knowmind login --token kmt_xxxxxxxx

3. Wire up your client:

Claude Code (one command)

claude mcp add knowmind --env KNOWMIND_TOKEN=kmt_xxx -- npx -y knowmind mcp

Cursor (~/.cursor/mcp.json) — also works for Claude Desktop, Windsurf, Cline, Continue, Goose, and Zed with their respective config files:

{
  "mcpServers": {
    "knowmind": {
      "command": "npx",
      "args": ["-y", "knowmind", "mcp"],
      "env": { "KNOWMIND_TOKEN": "kmt_xxx" }
    }
  }
}

Any other MCP client: knowmind is a standard MCP server over stdio (npx -y knowmind mcp). On Windows, if npx does not start directly, use "command": "cmd", "args": ["/c", "npx", "-y", "knowmind", "mcp"].

npx -y knowmind install <ide> writes this configuration for you (e.g. claude, cursor, vscode), and npx -y knowmind init sets up automatic memory hygiene — recall before each task, store after each meaningful change — for clients with a hook or rule mechanism (Claude Code, Cursor).

How knowmind stores facts

• Bitemporal history. Every fact carries two time axes: when it was true and when it was recorded. Corrections never overwrite the original; the old statement stays queryable with the date it stopped being valid, so you can reconstruct what the system knew on any given day.
• Provenance and confidence per fact. New facts require a confidence level and keep a link to their source. Older facts without a confidence level are marked as such.
• Typed knowledge graph. Entities and relations use a restricted set of edge types; catch-all relations are rejected at write time.
• Operated in the EU, isolated per tenant. The service runs on Hetzner in Nuremberg, Germany, with tenant isolation, a public data processing agreement, and a subprocessor list at knowmind.de/legal/avv. Access logs are hash-chained and externally timestamped (RFC 3161).

knowmind is a hosted service; there is no self-hosted community edition. If you need self-hosting, one of the projects below will serve you better. knowmind is built for the people and teams that need an operated memory service with an audit trail in the EU.
