Zapier
Run actions in 9,000+ apps through the connections saved in a Zapier account.
Updated Sep 27, 2026
Overview
Zapier is an automation platform with integrations for 9,000+ apps and 40,000+
actions. Its hosted MCP server and the zapier-sdk CLI let an agent find and
run those actions, such as sending a Slack message or looking up a contact,
through the app connections already saved in a Zapier account, so the agent
never handles a third-party API key. The MCP server signs in with OAuth from
inside the MCP client, and Zapier creates the server during that sign-in; in
its default agentic mode the agent discovers and enables actions itself. The
CLI signs in through the browser with zapier-sdk login. Each successful MCP
tool call uses two tasks from the Zapier plan.
Zapier's REST APIs on api.zapier.com serve partners that embed Zapier in
their own product: running an action through them needs a public Zapier
integration or White Label access.
