PatternFly MCP Server

A Model Context Protocol (MCP) server that provides access to PatternFly rules and documentation, built with Node.js.

The PatternFly MCP server is a comprehensive library resource for PatternFly. It is intended to be extensible to meet the needs of different teams and projects, from simple to complex, from design to development. Read more about our roadmap and how we've structured the server in our architecture docs.

Requirements

• Node.js 20+
• NPM (or equivalent package manager)

Quick Start

The PatternFly MCP Server supports multiple configurations; see the usage documentation for details.

For integrated use with an IDE

Set a basic MCP configuration

Minimal configuration

{
  "mcpServers": {
    "patternfly-docs": {
      "command": "npx",
      "args": ["-y", "@patternfly/patternfly-mcp@latest"],
      "description": "PatternFly rules and documentation"
    }
  }
}

HTTP transport mode

{
  "mcpServers": {
    "patternfly-docs": {
      "command": "npx",
      "args": ["-y", "@patternfly/patternfly-mcp@latest", "--http", "--port", "8080"],
      "description": "PatternFly docs (HTTP transport)"
    }
  }
}

See the MCP Server Configuration documentation for more examples.

For development, advanced usage

Run the server directly

Run the server immediately via npx:

npx -y @patternfly/patternfly-mcp

Or with options

npx -y @patternfly/patternfly-mcp --log-stderr --verbose

Inspect the server

Visualize and test the MCP interface:

npx -y @modelcontextprotocol/inspector npx @patternfly/patternfly-mcp

Embed the server in your application

import { start } from '@patternfly/patternfly-mcp';

// Remember to avoid using console.log and info, they pollute STDOUT
async function main() {
  const server = await start();

  // Graceful shutdown
  process.on('SIGINT', async () => {
    await server.stop();
    process.exit(0);
  });
}

main();

See the development documentation for additional examples, CLI and embedded server options.
