Overview of mcp-golang

Title

mcp-golang – Unofficial Go implementation of the Model Context Protocol (MCP)

go get github.com/metoro-io/mcp-golang

Server Example: Define tools, prompts, and resources with native Go structs and register them with the MCP server.
Client Example: Initialize a client, call tools with type-safe arguments, and handle responses.
HTTP/Gin Support: Use HTTP-based transports for stateless communication (no bidirectional features).

🛡️ Type Safety: Define tool arguments as Go structs with automatic schema generation and deserialization.
🚛 Custom Transports: Supports stdio (full bidirectional), HTTP (stateless), Gin, SSE, and custom transports.
⚡ Low Boilerplate: Auto-generates MCP endpoints, reducing manual setup.
🧩 Modular Design: Split into transport, protocol, and server/client components for flexibility.
🔄 Bi-directional Support: Full server and client capabilities via stdio transport.

AI Tool Integration: Build MCP-compatible servers for AI models (e.g., Claude Desktop).
Kubernetes Monitoring: Example: Metoro uses mcp-golang to query Kubernetes environments.
Custom Workflows: Extend with custom transports (e.g., WebSockets, gRPC) for specialized use cases.
