Auto-generated overview of what this skill does and when to reach for it.
Official Go library to build and connect servers and clients that speak the Model Context Protocol (MCP).
Use this when
- You need to expose tools or resources from a Go service via MCP
- You want to connect a Go app to an MCP-compatible AI assistant
- You’re building a custom MCP transport layer in Go
- You need OAuth support for MCP servers or clients
- You’re prototyping a new MCP feature and want spec-compliant scaffolding
Don't use when
- You only need a quick CLI tool with no MCP integration
- Your runtime isn’t Go and you need a different language SDK
Capabilities
- Provides mcp.Server and mcp.Client for building servers and clients
- Includes StdioTransport and CommandTransport for basic I/O
- Supports adding tools, resources, and prompts to servers
- Includes jsonrpc package for custom transport implementations
- Offers auth and oauthex packages for OAuth flows
- Maps full MCP spec versions to Go package APIs
