Zapier launched an MCP server exposing its 7,000+ app integrations as tools callable by any MCP-compatible AI agent. This allows agents to trigger Zaps, send emails, create CRM records, and perform cross-app automations through a single MCP interface.
Connected Systems
| System | Type | Direction | Auth Method | Notes |
|---|---|---|---|---|
| Zapier Actions API | Integration Layer | Read/Write | OAuth per app | Exposes Zaps and app actions as REST endpoints |
| MCP Server (Zapier) | Tool Registry | Read/Write | User API key | Wraps Actions API as typed MCP tools |
| Claude / GPT-4 | AI Clients | Inbound | API Key | Primary AI client consumers |
| Zapier Auth | Auth Provider | Outbound | OAuth 2.0 | OAuth per connected app |
Architecture Pattern
Federated Registry — each user's enabled Zapier actions appear as individual tools in their personal MCP tool registry. No central gateway; each user's token scopes their available tools.
Governance Controls
- Consent-based writes: Write actions (send email, create record) require explicit user consent during Zapier's OAuth flow
- Scope isolation: Tool availability is scoped to the authenticated user's connected apps
- No cross-user access: Each token is strictly user-scoped with no cross-account access
Outcomes
- AI agents can now trigger any of Zapier's 7,000+ app integrations through a unified MCP interface
- Enables complex multi-app automation workflows driven entirely by natural language agent instructions
