Copilot MCP Tool

GitHub Release npm version npm downloads License: MIT Open Source

Copilot MCP Tool is an open‑source Model Context Protocol (MCP) server that connects your IDE or AI assistant (Claude, Cursor, etc.) to GitHub Copilot CLI. It enables non‑interactive automation, safe tool execution with permissions, and large‑scale code analysis via @ file references. Built for reliability and speed, it streams progress updates, and integrates cleanly with standard MCP clients for code review, refactoring, documentation, and CI automation.

  • Primary: Ask GitHub Copilot CLI questions from your MCP client, with comprehensive tool management
  • Advanced: Batch processing, code review, and brainstorming capabilities
Copilot MCP server

TLDR: Claude + GitHub Copilot CLI

Goal: Use GitHub Copilot CLI directly from your MCP-enabled editor to analyze and edit code efficiently.

Prerequisites

Before using this tool, ensure you have:

  1. Node.js (v18.0.0 or higher)
  2. GitHub Copilot CLI - Required

One-Line Setup

claude mcp add copilot-cli -- npx -y @trishchuk/copilot-mcp-server

Verify Installation

Type /mcp inside Claude Code to verify the Copilot MCP is active.

Alternative: Import from Claude Desktop

If you already have it configured in Claude Desktop:

  1. Add to your Claude Desktop config:
"copilot-cli": {
  "command": "npx",
  "args": ["-y", "@trishchuk/copilot-mcp-server"]
}
  1. Import to Claude Code:
claude mcp add-from-claude-desktop

Configuration

Register the MCP server with your MCP client:

For NPX Usage (Recommended)

Add this configuration to your Claude Desktop config file:

{
  "mcpServers": {
    "copilot-cli": {
      "command": "npx",
      "args": ["-y", "@trishchuk/copilot-mcp-server"],
      "env": {
        "COPILOT_MODEL": "claude-sonnet-4.5"
      }
    }
  }
}

For Global Installation

If you installed globally, use this configuration instead:

{
  "mcpServers": {
    "copilot-cli": {
      "command": "copilot-mcp",
      "env": {
        "COPILOT_MODEL": "claude-sonnet-4.5"
      }
    }
  }
}

Configuration File Locations:

  • Claude Desktop:
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
    • Linux: ~/.config/claude/claude_desktop_config.json

After updating the configuration, restart your terminal session.

Environment Variables

Configure default behavior with environment variables:

COPILOT_MODEL - Default AI Model

Method 1: In MCP Configuration (Recommended)

Add the env field to your MCP server configuration:

{
  "mcpServers": {
    "copilot-cli": {
      "command": "npx",
      "args": ["-y", "@trishchuk/copilot-mcp-server"],
      "env": {
        "COPILOT_MODEL": "claude-sonnet-4.5"
      }
    }
  }
}

Method 2: System Environment Variable

# Set for current session
export COPILOT_MODEL=claude-sonnet-4.5

# Permanently (add to ~/.bashrc or ~/.zshrc)
echo 'export COPILOT_MODEL=claude-sonnet-4.5' >> ~/.zshrc

Available models:

  • claude-sonnet-4.5 - Default, best for code generation
  • claude-sonnet-4 - Faster version
  • gpt-5 - OpenAI GPT-5

Priority: model parameter > COPILOT_MODEL env > Copilot CLI default (claude-sonnet-4.5)

Override in requests:

# Uses COPILOT_MODEL
Use ask tool to analyze @src/

# Overrides with gpt-5
Use ask tool with model gpt-5 to analyze @src/
COPILOT_MCP_CWD - Working Directory

Purpose: Sets the working directory for Copilot CLI command execution. This is especially important when the MCP server starts from a different directory than your project (e.g., from home directory in IDE integrations).

Method 1: In MCP Configuration (Recommended for IDE)

{
  "mcpServers": {
    "copilot-cli": {
      "command": "npx",
      "args": ["-y", "@trishchuk/copilot-mcp-server"],
      "env": {
        "COPILOT_MCP_CWD": "/absolute/path/to/your/project"
      }
    }
  }
}

Method 2: System Environment Variable

# Set for current session
export COPILOT_MCP_CWD=/path/to/your/project

# Permanently (add to ~/.bashrc or ~/.zshrc)
echo 'export COPILOT_MCP_CWD=/path/to/your/project' >> ~/.zshrc

Resolution Priority:

  1. workingDir parameter in request (highest)
  2. COPILOT_MCP_CWD env variable
  3. PWD or INIT_CWD env variables
  4. Auto-inferred from @path in prompt
  5. process.cwd() (lowest)

Override in requests:

# Use explicit workingDir parameter
Use ask tool with workingDir "/path/to/project" to analyze the codebase

For IntelliJ IDEA / IDE Users: If Copilot CLI cannot find your project files, set COPILOT_MCP_CWD in your MCP server configuration to point to your project directory.

See Getting Started Guide for full configuration details.

Example Workflow

  • Natural language: "use copilot to explain index.html", "understand this repo with @src", "look for vulnerabilities and suggest fixes"
  • Claude Code: Type /copilot to access the MCP server tools.

Usage Examples

GitHub Copilot CLI

// Use GitHub Copilot CLI for analysis
'explain the architecture of @src/';

// Code review with specific focus
'use copilot to review @src/main.ts for security vulnerabilities';

// Batch processing multiple files
'use batch to refactor all JavaScript files in @src/ for ES6 syntax';

// Comprehensive code review
'use review to perform security review of @api/ with high severity filter';

With File References (using @ syntax)

  • ask copilot to analyze @src/main.ts and explain what it does
  • use copilot to summarize @. the current directory
  • analyze @package.json and list dependencies using copilot

General Questions (without files)

  • ask copilot to explain div centering
  • ask copilot about best practices for React development
  • use copilot for TypeScript debugging help

Advanced Examples

// GitHub Copilot CLI batch processing
'use batch to update all React components in @src/components/ for React 18 patterns';

// Comprehensive code review
'use review for security review of @api/ with critical severity filter and fix suggestions';

// Multiple task processing
'use batch to: 1) add JSDoc comments to @utils.js, 2) fix ESLint issues in @main.ts, 3) update imports in @index.js';

Brainstorming & Ideation

  • brainstorm ways to optimize our CI/CD pipeline using SCAMPER method
  • use copilot to brainstorm 10 innovative features for our app
  • ask copilot to generate product ideas for the healthcare domain with design-thinking approach

Tool Permissions & Safety

GitHub Copilot CLI supports tool permissions and directory access controls. This server defaults to allowing all tools for non-interactive mode.

  • use copilot to create and run a Python script that processes data
  • ask copilot to safely test @script.py and explain what it does
