Drone MCP Server

A Model Context Protocol (MCP) server for interacting with Drone CI/CD. This server provides tools and resources to query build information, repositories, and more from your Drone instance.

Features

• List repositories: Get all repositories in your Drone instance
• List builds: List builds for a specific repository
• Get build details: Retrieve detailed information about a specific build
• Resource access: Access build details via resource URIs

Installation

go mod tidy
go build -o drone-mcp-server .

Configuration

Set the following environment variables:

export DRONE_SERVER=https://drone.example.com
export DRONE_TOKEN=your_drone_token
# Optional: For SSE transport authentication
export MCP_AUTH_TOKEN=your_sse_auth_token

The DRONE_TOKEN should be a personal access token with appropriate permissions to read repositories and builds.

SSE Authentication: When using SSE transport, you can optionally set MCP_AUTH_TOKEN to require Bearer token authentication. Clients must include Authorization: Bearer <token> header in their requests. If not set, SSE endpoints will be publicly accessible (use with caution in production).

Usage

As an MCP server

Add the server to your MCP client configuration (e.g., Claude Desktop):

{
  "mcpServers": {
    "drone": {
      "command": "/path/to/drone-mcp-server",
      "env": {
        "DRONE_SERVER": "https://drone.example.com",
        "DRONE_TOKEN": "your_token"
      }
    }
  }
}

Direct execution

You can run the server directly for testing:

# Stdio mode (default)
./drone-mcp-server

# SSE HTTP mode
./drone-mcp-server --sse --host localhost --port 8080

Transport Modes

1. Stdio mode (default): Communicates via stdin/stdout using the MCP protocol. Suitable for local integration with MCP clients.

2. SSE HTTP mode: Uses Server-Sent Events (SSE) over HTTP. Suitable for remote access or testing.

   server.ts

   Copy

   # Without authentication (public access)
   ./drone-mcp-server --sse --host 0.0.0.0 --port 8080
   
   # With authentication (recommended for production)
    export MCP_AUTH_TOKEN=your-secret-token
   ./drone-mcp-server --sse --host 0.0.0.0 --port 8080
   

   The server will be available at http://localhost:8080/ for SSE connections.

   Authentication: If MCP_AUTH_TOKEN is set, clients must include the header:

   Code

   Copy

   Authorization: Bearer your-secret-token
