**APIs profiled:** 9

Smithery is a platform for discovering, deploying, and managing Model Context Protocol (MCP) servers and skills. It operates a public registry of community-built MCP extensions that AI agents can use to access external tools, data sources, and services, plus a Connect gateway that bundles connections in a namespace behind a single MCP endpoint at mcp.smithery.run. The platform exposes APIs for server registry browsing, server deployment, skill publishing, namespace management, scoped service tokens, connection lifecycle, trigger subscriptions, and an MCP transport endpoint for AI-agent integration.
