Coldstart MCP Server

Self-maintaining codebase knowledge for AI coding agents. Agent-written notes that stay anchored to your code - plus fast, deterministic navigation - so Claude Code, Codex, and Cursor stop rediscovering the repo every session. It runs locally over stdio via the published package.

People who work with ast, code intelligence and tree sitter and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Coldstart

Claude Code

claude mcp add akashgoenka-coldstart -- npx -y @cstart/coldstart

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "akashgoenka-coldstart": {
      "command": "npx",
      "args": [
        "-y",
        "@cstart/coldstart"
      ]
    }
  }
}

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

license MIT - declared in the repository

npm package @cstart/coldstart - the @cstart scope differs from the repo owner (akashgoenka); confirm it's the project's official package

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

03 · What Coldstart can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

1. It's a routing layer plus an agent-written notebook - no semantic analysis or generated code summaries. This is deliberate: the consuming agent is the semantic layer (see PHILOSOPHY.md). 2. gs callers are one-hop and file-scoped. Member-expression calls (this.method(), api.method()) aren't cross-file resolved; named function/constant calls are. Chase further hops by calling gs on the caller files. 3. Dynamic/compu
