Calm MCP

A live, graph-verified map of your codebase - so an AI coding agent can edit with its eyes open instead of grepping in the dark. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Calm MCP

Claude Code

claude mcp add eilodon-calm -- npx -y @eilodon/calm-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "eilodon-calm": {
      "command": "npx",
      "args": [
        "-y",
        "@eilodon/calm-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
