How to give your coding agent a repo map and code search with Repo Context MCP

Add the MCP server so the agent can map the repo, search code and pack context without walking node_modules.

Short answer: Install Node.js 18+; then add a server with command npx, args -y Repo Context MCP, and REPO_CONTEXT_ROOT set to your repo; Restart your MCP client. All steps.

Who it is forA developer whose agent wastes tokens re-reading irrelevant files in a monorepo.

The problemAgents miss entrypoints and paste random files into context.

The outcomeThree focused tools: repo_map, search_code and pack_context.

What you need first

  • Node.js 18+

Steps

  1. Install Node.js 18+
  2. Add a server with command npx, args -y Repo Context MCP, and REPO_CONTEXT_ROOT set to your repo
  3. Restart your MCP client
  4. Ask the agent to call repo_map before editing

Prompt for your agent

With repo-context-mcp configured for <repo>, call repo_map, then search_code for <symbol>, and list the path:line hits. Confirm node_modules was not included.

Caveat. It uses stdio transport, so each client starts its own local server process.
