hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
Integrations
Provides tools to retrieve available Nx plugins from the npm registry along with their descriptions through the nx_available_plugins tool.
Provides deep access to Nx monorepo structure, including project relationships, file mappings, tasks, ownership info, tech stacks, generators, and documentation to help LLMs generate tailored code and understand architectural impact of changes.
Nx MCP Server
A Model Context Protocol server implementation for Nx.
Overview
The Nx MCP server gives LLMs deep access to your monorepo’s structure: project relationships, file mappings, runnable tasks, ownership info, tech stacks, Nx generators, and even Nx documentation. With this context, LLMs can generate code tailored to your stack, understand the impact of a change, and apply modifications across connected files with precision. This is possible because Nx already understands the higher-level architecture of your workspace, and monorepos bring all relevant projects into one place.

Installation and Usage
There are two ways to use this MCP server:
a) Run it via the nx-mcp package
Simply invoke the MCP server via npx
or your package manager's equivalent.
Here's an example of a mcp.json
configuration:
For VSCode you can also run:
Refer to your AI tool's documentation for how to register an MCP server. For example, Cursor or Claude Desktop support MCP.
If you want to host the server instead of communicating via stdio
, you can use the --sse
and --port
flags. Keep in mind that the Nx MCP server only supports a single concurrent connection right now, so connecting multiple clients at the same time might break in some cases.
Run nx-mcp --help
to see what options are available.
b) Use the Nx Console extension
If you're using Cursor you can directly install the Nx Console extension which automatically manages the MCP server for you.

Available Tools
Currently, the Nx MCP server provides a set of tools. Resources, Roots and Prompts aren't supported yet.
- nx_workspace: Returns an annotated representation of the local nx configuration and the project graph
- nx_project_details: Returns the full project configuration for a specific nx project
- nx_docs: Retrieves documentation sections relevant to user queries
- nx_generators: Returns a list of available generators in the workspace
- nx_generator_schema: Provides detailed schema information for a specific generator
- nx_available_plugins: Returns a list of available Nx plugins from the npm registry with their descriptions
When no workspace path is specified, only the nx_docs
and nx_available_plugins
tools will be available.
Contributing & Development
Contributions are welcome! Please see the Nx Console contribution guide for more details.
The basic steps are:
- Clone the Nx Console repository and follow installation steps
- Build the
nx-mcp
usingnx run nx-mcp:build
(ornx run nx-mcp:build:debug
for debugging with source maps) - Use the MCP Inspector to test out your changes
