Frequently Asked Questions
How do I connect Zapier to my app?
Use Weavz Hosted Connect for Custom authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does Zapier support?
Zapier supports 16 tools including List Apps, List Actions, List Authentications, Get Input Fields, Get Output Fields, and more.
Can I use Zapier with AI agents?
Yes. Add Zapier to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect Zapier to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add Zapier as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped Zapier tools exposed by that workspace.
Does Zapier work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved Zapier work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with Zapier?
Zapier exposes 16 tools, including List Apps, List Actions, List Authentications, Get Input Fields, Get Output Fields, and more. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can Zapier be used in stateful agent workflows?
Yes. Agents can combine Zapier tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
What authentication does Zapier use?
Zapier uses Custom. Weavz stores credentials securely and uses them for authorized action execution.
How much does the Zapier integration cost?
The Zapier integration is included on all Weavz plans including the free tier with 20,000 actions per month. No credit card required.
What triggers does Zapier support?
Zapier supports 2 triggers including Zapier Webhook Received, MCP Callback Received.
