🚀 Single Binary Solution

• Replace multiple potentially resource-heavy Node.js/Python MCP servers, each spawned for every client tool you use
• One binary, one configuration, consistent performance
• Built in Go for speed and efficiency
• Minimal memory footprint compared to multiple separate servers
• Fast startup and response times
• Download one binary, configure once - or compile from source
• Optional dependencies only for specific tools
• Works out of the box for most tools

🛠 Comprehensive Tool Suite

• 12+ essential developer tools in one package
• No need to manage multiple MCP server installations
• Consistent API across all tools

You must have a recent version of Go installed.

1. Install the latest MCP DevTools binary:

go install github.com/sammcj/mcp-devtools@HEAD
echo "${GOPATH}/bin/mcp-devtools" # Use this path in your MCP configuration, if your GOPATH is not set, please check your Go installation / configuration.

# If you're on macOS, you'll also need to run the following command to allow the downloaded binary to run:
xattr -r -d com.apple.quarantine ${GOPATH}/bin/mcp-devtools

2. Update your MCP client to add the MCP DevTools server configuration, replacing /path/to/mcp-devtools with the actual path to the binary (e.g. /Users/samm/go/bin/mcp-devtools):

{
  "mcpServers": {
    "dev-tools": {
      "type": "stdio",
      "command": "/path/to/mcp-devtools",
      "env": {
        "DISABLED_FUNCTIONS": "brave_local_search,brave_video_search" // Optional, disable specific tools if not needed
      }
    }
  }
}

See below for various environment variables you can set to configure specific features.

👉 See detailed tool documentation

Option 1: Go Install

go install github.com/sammcj/mcp-devtools@HEAD

Option 2: Build from Source

git clone https://github.com/sammcj/mcp-devtools.git
cd mcp-devtools
make build

Option 3: Download Release Download the latest binary from releases and place in your PATH and remember to check for updates!

STDIO

{
  "mcpServers": {
    "dev-tools": {
      "type": "stdio",
      "command": "/path/to/mcp-devtools",
      "env": {
        "BRAVE_API_KEY": "This is optional - remove if not needed",
      }
    }
  }
}

Replacing /path/to/mcp-devtools with your actual binary path (e.g., /Users/yourname/go/bin/mcp-devtools).

Note: The BRAVE_API_KEY is optional and only needed if you want to use the Brave Search provider, there are other providers available, see the various tools documentation for more details.

Streamable HTTP

mcp-devtools --transport http --port 8080

{
  "mcpServers": {
    "dev-tools": {
      "type": "streamableHttp",
      "url": "http://localhost:8080/http"
    }
  }
}

MCP DevTools supports three transport modes for different use cases:

Best for: Simple, local use with MCP clients like Claude Desktop, Cline, etc.

{
  "mcpServers": {
    "dev-tools": {
      "type": "stdio",
      "command": "/path/to/mcp-devtools",
      "env": {
        "BRAVE_API_KEY": "your-api-key-if-needed"
      }
    }
  }
}

Best for: Production deployments, shared use, centralised configuration

# Basic HTTP mode
mcp-devtools --transport http --port 8080

# With authentication
mcp-devtools --transport http --port 8080 --auth-token mysecrettoken

# With OAuth (see OAuth documentation)
mcp-devtools --transport http --port 8080 --oauth-enabled

Client Configuration:

{
  "mcpServers": {
    "dev-tools": {
      "type": "streamableHttp",
      "url": "http://localhost:8080/http",
      "headers": {
        "Authorization": "Bearer mysecrettoken"
      }
    }
  }
}

Best for: Real-time applications, web dashboards

mcp-devtools --transport sse --port 18080 --base-url http://localhost

Client Configuration:

{
  "mcpServers": {
    "dev-tools": {
      "type": "sse",
      "url": "http://localhost:18080/sse"
    }
  }
}

All environment variables are optional, but if you want to use specific search providers or document processing features, you may need to provide the the appropriate variables.

Core Tools:

• BRAVE_API_KEY - Enable Brave Search provider by providing a (free Brave search API key)
• SEARXNG_BASE_URL - Enable SearXNG search provider by providing the base URL (e.g. https://searxng.example.com)
• MEMORY_FILE_PATH - Memory storage location (default: ~/.mcp-devtools/)
• DISABLED_FUNCTIONS - Comma-separated list of functions to disable (e.g. think,internet_search)

Filesystem Tool (Security-Sensitive):

• FILESYSTEM_TOOL_ENABLE - Set to "true" to enable filesystem operations (disabled by default)
• FILESYSTEM_TOOL_ALLOWED_DIRS - Colon-separated (Unix) list of allowed directories

Document Processing:

• DOCLING_PYTHON_PATH - Python executable path (default: auto-detected)
• DOCLING_CACHE_ENABLED - Enable processed document cache (default: true)
• DOCLING_HARDWARE_ACCELERATION - Hardware acceleration (auto (default), mps, cuda, cpu)

• --transport, -t - Transport type (stdio, sse, http). Default: stdio
• --port - Port for HTTP transports. Default: 18080
• --base-url - Base URL for HTTP transports. Default: http://localhost
• --auth-token - Authentication token for HTTP transport
• --debug, -d - Enable debug logging

MCP DevTools uses a modular architecture:

• Tool Registry: Central registry managing tool discovery and registration
• Tool Interface: Standardised interface all tools implement
• Transport Layer: Supports STDIO, HTTP, and SSE transports
• Plugin System: Easy to add new tools following the interface

Each tool is self-contained and registers automatically when the binary starts.

For production deployments requiring centralised user authentication:

👉 Complete OAuth Setup Guide

Quick example:

# Browser-based authentication
mcp-devtools --transport http --oauth-browser-auth --oauth-client-id="your-client"

# Resource server mode
mcp-devtools --transport http --oauth-enabled --oauth-issuer="https://auth.example.com"

# Pull latest image
docker pull ghcr.io/sammcj/mcp-devtools:latest

# Run with environment variables
docker run -e BRAVE_API_KEY="your-key" ghcr.io/sammcj/mcp-devtools:latest
