Zapier MCP

Hosted MCP connecting AI clients to 9,000+ apps

Zapier MCP connects Claude, ChatGPT, Cursor or any AI client to 9,000+ apps. The agent finds the right action and runs it, with auth and permissions managed by Zapier. The GitHub repo is the official plugin distribution for the hosted Zapier MCP server.

The integration layer: hundreds of managed tools your agents can call.

Composio handles auth, schemas, observability and reliability for the external SaaS tools an agent uses — 'plumbing for agentic actions' across Slack, GitHub, Salesforce and 250+ other surfaces.

A registry and toolchain for MCP servers.

Smithery indexes and helps deploy MCP (Model Context Protocol) servers — a distribution layer for the tool ecosystem agents connect to.

Exa

Search API purpose-built for AI agents.

Exa (formerly Metaphor) provides neural search and web-crawl APIs tuned for agent consumption — live, cited knowledge for agents instead of stale training data.
