What it does

This server provides a reference implementation for the Model Context Protocol using Go, specifically utilizing the SSE (Server-Sent Events) transport layer. It allows AI agents to communicate with a backend over HTTP rather than standard stdio, making it suitable for cloud deployments and remote access.

Tools

Example Tools: The server implements a set of example tools to demonstrate capability, including functionality for basic data retrieval and processing.
NATS & Postgres Integration: A specialized branch (nats-postgres) implements real-world tools for reading from a PostgreSQL database and writing to a NATS channel.

Installation

To run the server locally:

go build . && ./mcp-go-sse-server --transport sse --baseurl http://localhost

For Claude Desktop configuration, use the SSE endpoint provided by the running server:

{
  "mcpServers": {
    "go-sse-server": {
      "url": "http://localhost:8080/sse"
    }
  }
}
