Rebuild Dossier MCP Server

An MCP server that reverse-engineers a trustworthy rebuild spec - a locked CLAUDE.md, .claude/ config, and a mutation-tested test suite - out of an existing app, so any coding agent can rebuild it cleanly against that spec instead of guessing. It runs locally over stdio via the published package.

People who work with agent tools, ai evaluation and arxiv and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

before you install - you'll need

Set MCP_AUTH_TOKEN, MCP_ALLOWED_HOSTS, REBUILD_DOSSIER_ALLOWED_PATHS before connecting.

Claude Code

claude mcp add parker-fawcett-rebuild-dossier -- npx -y rebuild-dossier

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "parker-fawcett-rebuild-dossier": {
      "command": "npx",
      "args": [
        "-y",
        "rebuild-dossier"
      ]
    }
  }
}

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

Using another client? Same JSON, different key
