Swarmnest MCP server

Swarmnest MCP Server

Search the Swarmnest directory from any MCP client: thousands of hand-checked AI agent tools, APIs, MCP servers and data sources in 160+ categories, 500+ Agent Skills, and the Swarmnest Marketplace. Free, read-only, no API key.

Remote endpoint: https://swarmnest.ai/mcp (Streamable HTTP) Docs: https://swarmnest.ai/mcp-server/

Tools

Every result includes canonical swarmnest.ai URLs. Agent Skills are made by third-party developers, so skill results carry an install warning: review the source before installing.
