nx-mcp MCP Server Integration

What does “nx-mcp” MCP Server do?

The nx-mcp MCP (Model Context Protocol) Server is an integration tool designed to bridge Nx (a popular build system for monorepos) with AI assistants and LLM-based workflows. It exposes Nx’s capabilities through the MCP interface, allowing AI clients to interact programmatically with Nx workspaces. This server enables tasks such as workspace analysis, project management, and execution of Nx commands through API-like endpoints. By connecting Nx to external data sources, plugins, or development tools, the nx-mcp server enhances automation, simplifies development workflows, and empowers AI-powered agents to assist developers with queries, actions, and resource management within an Nx-based codebase.

Use Cases of this MCP Server

• Automation of Workspace Tasks: Enables AI assistants to execute Nx commands (e.g., build, test, lint) programmatically for automation and workflow improvement.
• Monorepo Analysis: Allows LLMs to analyze and provide insights about project structure, dependencies, and configurations in Nx workspaces.
• Project Management: Facilitates the management of multiple projects within a monorepo by enabling AI-driven queries or actions.
• Nx Plugin Integration: Offers a pathway for AI agents to leverage custom Nx plugins or scripts through standardized protocols.
• Developer Onboarding: Assists new developers by providing interactive guidance, documentation, or automation within Nx-managed repositories.

How to set it up

Windsurf

1. Ensure you have Node.js installed.
2. Open your Windsurf configuration file (usually windsurf.json).
3. Add the nx-mcp MCP server to the mcpServers section:

   {
     "mcpServers": {
       "nx-mcp": {
         "command": "npx",
         "args": ["@nrwl/nx-mcp@latest"]
       }
     }
   }
   

4. Save the configuration and restart Windsurf.
5. Verify by running a test command or querying the MCP status.

Claude

1. Install Node.js.
2. Locate the Claude configuration file for MCP servers.
3. Insert the following in your MCP configuration:

   {
     "mcpServers": {
       "nx-mcp": {
         "command": "npx",
         "args": ["@nrwl/nx-mcp@latest"]
       }
     }
   }
   

4. Restart Claude and confirm the MCP server is active.

Cursor

1. Confirm Node.js is available.
2. Edit the Cursor MCP configuration (e.g., cursor.json).
3. Add the nx-mcp server:

   {
     "mcpServers": {
       "nx-mcp": {
         "command": "npx",
         "args": ["@nrwl/nx-mcp@latest"]
       }
     }
   }
   

4. Save and restart Cursor.
5. Check integration by issuing an Nx-related MCP request.

Cline

1. Install Node.js if not already present.
2. Open your Cline configuration file.
3. Register the nx-mcp server in the MCP section:

   {
     "mcpServers": {
       "nx-mcp": {
         "command": "npx",
         "args": ["@nrwl/nx-mcp@latest"]
       }
     }
   }
   

4. Save changes and restart Cline.
5. Verify setup by sending a sample MCP query.

Securing API Keys

To secure API keys, use environment variables and reference them in your configuration. For example:

{
  "mcpServers": {
    "nx-mcp": {
      "command": "npx",
      "args": ["@nrwl/nx-mcp@latest"],
      "env": {
        "NX_API_KEY": "${NX_API_KEY}"
      },
      "inputs": {
        "api_key": "${NX_API_KEY}"
      }
    }
  }
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{ “nx-mcp”: { “transport”: “streamable_http”, “url”: “https://yourmcpserver.example/pathtothemcp/url" } }

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “nx-mcp” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

The nx-mcp MCP server offers a valuable foundation for integrating Nx with AI workflows, but the current documentation and implementation lack explicit prompts, resources, and tool definitions. Its real strengths lie in setup flexibility and potential for automation, but it would benefit from clearer protocol primitives and examples.

MCP Score

Rating: 3/10 — While the MCP concept and setup guidance are present, the lack of documented tools, prompts, resources, and clear licensing limits practical utility and adoption at this stage.
