Your AI, wired into 9,000+ apps

A remote MCP server that turns Zapier’s 40,000+ actions into tools your AI assistant can call. Send Slack messages, add Sheet rows, create GitHub issues, and more — by asking in natural language. Setup guides for every client live in the repo.
Who it's for
Anyone with an MCP client. Claude, ChatGPT, Cursor, Windsurf. No code required.
How to use it
Generate your server at mcp.zapier.com, point your client at the URL, and enable actions. Agentic mode ships 14 meta-tools so your AI can discover and enable actions itself.

Every app, one typed call

Docs and runnable examples for @zapier/zapier-sdk. One auth surface for 9,000+ apps; the SDK handles tokens, retries, and API differences. Agents get AGENTS.md and runtime discovery.
Who it's for
Developers and agents running app actions from backends, scripts, or agent code.
How to use it
Examples indexed three ways: by pattern, by app, and chained multi-app workflows.
npm install @zapier/zapier-sdk
npx zapier-sdk login
# or, as an agent skill:
npx skills add zapier/sdk

Teach your coding agent Zapier

Skills for AI coding agents, maintained by Zapier teams in the open Agent Skills format and indexed by skills.sh. First up: skills for building, inspecting, and modifying Zapier Workflows, with more team folders coming soon.
Who it's for
Claude Code, Cursor, and Copilot users who want their agent to use Zapier well, without re-explaining it every session.
How to use it
Install once; your agent invokes the right skill automatically when a matching task shows up.
npx skills add zapier/agent-skills
# or just one skill:
npx skills add zapier/agent-skills --skill <skill-name>

The GTM team's coding agent playbook

The skills Zapier’s own GTM teams use to turn scattered context into reviewable work: campaign planning, lead follow-up QA, account prioritization, support triage, and customer storytelling. A field guide, not a prompt library — every workflow is source-backed with human approvals built in.
Who it's for
Marketing, sales, and customer-ops teams using coding agents like Codex, Claude Code, and Cursor with real business context.
How to use it
Start with docs/vp-marketing-skill-breakdown.md for the business view, find your workflow in registry/skills.csv, then open that skill’s folder and connect it to your approved systems.

Where 9,000+ integrations come from

The monorepo behind the Zapier developer platform: the CLI, the core runtime every app depends on, the schema that defines what an integration is, and a library of example apps.
Who it's for
Integration builders like partners and developers shipping or maintaining an app integration on Zapier.
npm install -g zapier-platform-cli
zapier login
zapier init my-app

App integrations as readable code

Per-app connectors in open TypeScript. Each app ships as both an agent skill and an MCP tool — same artifact, installable in Claude Code or registered into any MCP server. Notion and Slack are live; more apps are rolling out.
Who it's for
Agent builders who want per-app tools their agent can read, install, and adapt. Runs with your own credentials or a Zapier connection.
npx skills add zapier/connectors/notion
# or as an npm package:
npm install @zapier/notion-connector
