A single, high-performance MCP server that replaces many Node.js and Python-based MCP servers with one efficient Go binary, providing access to essential developer tools through a unified, modular interface that can be easily extended with new tools.

🚀 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 and because I'm not smart enough to write Rust
- Minimal memory footprint compared to multiple separate servers
- Fast startup and response times
- Download one binary, configure once - or compile from source
- Works out of the box for most tools
- OpenTelemetry support for tracing and metrics
🛠 Comprehensive Tool Suite For Agentic Coding
- 20+ essential developer agent tools in one package
- No need to manage multiple MCP server installations
- Consistent API across all tools
- Modular design with tool registry allowing for easy addition of new tools
If you have Golang installed, simply run go install github.com/sammcj/mcp-devtools@HEAD and it will be installed to your $GOPATH/bin.
There is also an experimental installer script:
curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bashThis will:
- Download the latest release and installs to an appropriate location (respects
$GOPATH/binor uses~/.local/bin) - Remove macOS quarantine attributes automatically
- Generate example MCP client configurations in
~/.mcp-devtools/examples/ - Open your file manager to show the example configs and show you where to configure your MCP clients

Customisation:
# Dry run (shows what would be done without making changes)
DRY_RUN=1 curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash
# Install to a specific directory
INSTALL_DIR=/custom/path curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash
# Install a specific version
VERSION=0.50.0 curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash
# Skip example config generation
NO_CONFIG=1 curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash
# Skip all confirmation prompts (for automation)
FORCE=1 curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash🔗 Manual Installation (Click Here)
You have a few other options to make MCP DevTools available to your MCP clients:
If you have Golang installed- If you do not have, and do not want to install Golang
The automated installer works great even if you have Golang installed:
curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bashThis will respect your $GOPATH/bin if it's in your PATH, and automatically configure example MCP client settings.
Note that while go run makes it easy to get started, it means every time your client starts to download the tool may not be what you want in the long run.
MCP Client Configuration:
{
"mcpServers": {
"dev-tools": {
"type": "stdio",
"command": "go",
"args": ["run", "github.com/sammcj/mcp-devtools@HEAD"],
"env": {
"ENABLE_ADDITIONAL_TOOLS": "security,sequential_thinking,code_skim,code_rename",
"DISABLED_TOOLS": "",
"NOTE_FOR_HUMANS": "A minimal set of tools are enabled by default, MCP DevTools provides many additional useful tools including efficient Context7 documentation search, Frontend UI Framework templates, Code search and optimisation and many others, visit https://github.com/sammcj/mcp-devtools for more information on available tools and configuration"
}
}
}
}Or if you're using Claude Code you can also add it via the CLI:
claude mcp add --transport stdio mcp-devtools go run github.com/sammcj/mcp-devtools@HEAD

- 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- Update your MCP client to add the MCP DevTools server configuration, replacing
/path/to/mcp-devtoolswith 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": {
"ENABLE_ADDITIONAL_TOOLS": "security,sequential_thinking,code_skim,code_rename",
"DISABLED_TOOLS": "",
"NOTE_FOR_HUMANS": "A minimal set of tools are enabled by default, MCP DevTools provides many additional useful tools including efficient Context7 documentation search, Frontend UI Framework templates, Code search and optimisation and many others, visit https://github.com/sammcj/mcp-devtools for more information on available tools and configuration"
}
}
}
}🔗 Click here for instructions
If you do not have, and do not want to install Golang, you can download the latest release binary from the releases page.
# 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 mcp-devtoolsConfigure your MCP client to use the downloaded binary (replacing /path/to/mcp-devtools ):
{
"mcpServers": {
"dev-tools": {
"type": "stdio",
"command": "/path/to/mcp-devtools",
"env": {
"ENABLE_ADDITIONAL_TOOLS": "security,sequential_thinking,code_skim,code_rename",
"DISABLED_TOOLS": "",
"NOTE_FOR_HUMANS": "A minimal set of tools are enabled by default, MCP DevTools provides many additional useful tools including efficient Context7 documentation search, Frontend UI Framework templates, Code search and optimisation and many others, visit https://github.com/sammcj/mcp-devtools for more information on available tools and configuration"
}
}
}
}These tools can be disabled by adding their function name to the DISABLED_TOOLS environment variable in your MCP configuration.
