Nx MCP

What it does

Gives an agent the dependency graph of an Nx monorepo, so it can answer which projects a change actually affects. On a large workspace that question is the difference between one build and forty. Best value in repositories where the graph is the hard part; redundant in a single-app repo.

Install

npx -y nx-mcp

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

{
  "mcpServers": {
    "nx": {
      "command": "npx",
      "args": [
        "-y",
        "nx-mcp"
      ]
    }
  }
}

When to use it

Reach for this when the task needs monorepo inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

Other TypeScript servers

• Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
• Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
• Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
