[!IMPORTANT] MCPcat is now AgentCat 🐱 — same team, same product, new name. This module was previously published as github.com/mcpcat/mcpcat-go-sdk, which keeps working forever, but new features land here. Upgrading takes a few minutes — see the migration guide.
[!NOTE] Looking for the Python SDK? Check it out here agentcat-python.
AgentCat helps developers and product owners build, improve, and monitor their MCP servers by capturing user analytics and tracing tool calls.
- User session replay 🎬. Follow alongside your users to understand why they're using your MCP servers, what functionality you're missing, and what clients they're coming from. - Trace debugging 🔍. See where your users are getting stuck, track and find when LLMs get confused by your API, and debug sessions across all deployments of your MCP server. - Existing platform support 📊. Get logging and tracing out of the box for your existing observability platforms (OpenTelemetry, Datadog, Sentry) — eliminating the tedious work of implementing telemetry yourself.
AgentCat provides first-class support for the two most popular Go MCP libraries:
Library Install ------------------ mcp-go (mark3labs) go get go.agentcat.com/sdk/mcpgo go-sdk (official) go get go.agentcat.com/sdk/officialsdk
Import the package that matches the MCP library you're already using. Both expose the same Track() API and share the same feature set.
