## Why I Built MCP DevTools
🚀 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
## Quickstart
### Quick Install / Update
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:
bash
curl -fsSL https://raw.githubusercontent.com/sammcj/mcp-devtools/main/install.sh | bash
