Let your agent connect to anything
Authenticated, governed access to the full Zapier catalog — in code, on behalf of your users. No OAuth flows. No token management. Zapier handles the keys.
When to use MCP vs. SDK
Use SDK when you're working with code or building Zapier capabilities into your app/product. Use MCP to expose Zapier connections to AI apps and agents that can't execute code.
Built for builders and their agents
Already using Zapier? The SDK is your next step — take your connected apps and put them to work in code.
Vibe coders & AI builders: Set up in an afternoon. Ship by end of day.
Already building in Cursor or Claude Code? Install SDK in 5 minutes. Your agent calls the same interface you do — Zapier handles auth, retries, and governance so neither of you has to.
Developers: Skip the Auth. Just build.
9,000+ prebuilt apps plus raw API access. One interface, no OAuth setup required. Your product calls it, your agent calls it — either way Zapier handles the integration layer.
Prosumers & non-devs: Your agent connects to your apps.
Being carried along by the agent wave. The SDK is what makes your agent actually do real work — connecting to the apps you already use.
How it works
01 - Install and initialize
One npm install. Run zapier-sdk login. That's it — you're authenticated. Whether you're writing the code or your agent is, the SDK gives you a programmable interface to the entire Zapier ecosystem from that point forward.
02 - Connect your apps once
Your existing Zapier connections are ready to go. If you need to add a new one, the SDK generates a connect link — your user authenticates through a Zapier-hosted flow and lands back in your context. Tokens, refresh logic, and retries never touch your code.
03 - Your agent takes action
Invoke any of 9,000+ apps across the full catalog, or use raw authenticated API calls to 3,000+ supported apps. Zapier's governance policies apply automatically — no extra config.
Everything we handle. Nothing you maintain.
Build through the surfaces you and your agent already use, while Zapier still handles the hard parts underneath.
✓ 9,000+ apps
✓ App + Action governance
✓ Auth managed for every app
✓ Raw API for 3,000+ apps
✓ 15yrs of API knowledge
✓ Rate limit handling

Your agent. Every app. Zapier handles the rest.
One interface for your code and your agents. Zapier handles the keys — you handle the logic.
