Leteo MCP Server

Your coding agent forgets everything when the session ends, and most of it when the context is compacted. Leteo is the memory it keeps: decisions, bug fixes, conventions and the discoveries that were expensive to make, stored in a local SQLite database and handed back when they are relevant.

People who work with agent memory, codex and developer tools and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Leteo

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add asanabrial-leteo -- npx -y @asanabrial/leteo

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "asanabrial-leteo": {
      "command": "npx",
      "args": [
        "-y",
        "@asanabrial/leteo"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-08-09 - young repo, little track record yet

license MIT - declared in the repository

npm package @asanabrial/leteo - published under the repo owner's npm scope (@asanabrial)

registry namespace io.github.asanabrial is GitHub-verified and matches the repo owner
