Zapier MCP Server
by Zapier
Access to 8,000+ integrated applications directly from AI agents and code via Model Context Protocol, enabling agents to take actions across entire ecosystems
Core Problem Solved
Enterprise systems are fragmented across dozens of SaaS applications, yet AI agents need unified access to tools and actions across all of them. Zapier MCP provides a single protocol interface to trigger actions in 8,000+ apps.
Before Zapier MCP: Build custom integrations for each app or give up on agent access
With Zapier MCP: One standardized protocol, 8,000+ apps automatically available
What is MCP?
Model Context Protocol is “USB-C for AI integrations”—a common standard that enables:
- Unified communication between AI systems and external applications
- Automatic capability discovery
- Consistent interface regardless of underlying app
Key insight: AI agents need explicit protocols that define what tools do, how to use them, and when to use them—exactly like how humans need UIs with labeled buttons.
Zapier MCP Architecture
Three-Part System
The MCP Host:
- Chatbot, IDE, or AI tool
- Central coordinator
- Manages client instances
- Controls permissions and security
The MCP Client:
- Handles communication
- Routes requests between host and server
- Translates commands to API calls
The MCP Server (Zapier):
- Connects to 8,000+ applications
- Exposes specific capabilities
- Handles authentication
- Executes actions

8,000+ Integrated Apps
When you ask “create a row in my spreadsheet,” the MCP client interprets the request and routes it to Zapier MCP, which calls the specific endpoint needed.
Capabilities
MCP provides three basic methods:
Prompts:
- Pre-defined templates for language models
- Users select via slash commands or menu options
- Enable quick access to common tasks
Resources:
- Structured data (files, database records, commit history)
- Provides additional context to AI
- Reference information the AI needs
Tools:
- Functions allowing models to take action
- Interact with APIs
- Write to files, databases, etc.
- Execute business logic
Practical Actions
Agents can:
- Send emails across Gmail, Outlook, etc.
- Create tasks in Asana, Monday, Jira
- Update records in Salesforce, HubSpot, Pipedrive
- Write rows to Google Sheets, Excel, Airtable
- Update databases
- Trigger webhooks
- Send messages to Slack
- Create calendar events
- Update CRM opportunities
- And 7000+ more actions
Zapier MCP Configuration
Setup Process
- Select apps – Choose which of 8,000+ apps to enable
- Configure actions – Set up which actions agents can perform
- Multiple actions – Set up multiple actions within a single connection
- Field mapping – AI guesses field values or you set them manually
- Deploy – Connect directly to Claude, Cursor, Zed
Multi-Action Support
Single connection can expose multiple actions:
- Send email + read email (from Gmail)
- Create task + update task + mark complete (from Asana)
- Add row + update row + delete row (from Sheets)
Agents can intelligently select which action to perform.
Hosts That Support Zapier MCP
Already integrated:
vs. Traditional Integration Approaches
Traditional API Integration
- Requires custom integration per app
- Developers anticipate integrations in advance
- When new apps needed, requires code changes
- Each API has different conventions
iPaaS (Before MCP)
- No-code, visual integration
- Pre-built connectors (thousands)
- Can trigger workflows
- But disconnected from AI agents
Zapier MCP (Modern Approach)
- Unified protocol for AI agents
- 8,000+ apps via standard interface
- No custom integration code needed
- Apps automatically expose capabilities
- More flexible and scalable
Practical Example: Multi-Step Workflow
Scenario: Sales agent receives customer request
1. Agent receives: "Customer wants invoice emailed"
2. Queries Zapier MCP for available actions
3. Gets: [read_crm_account, send_email, create_ticket, etc.]
4. Selects: read_crm_account (to get email)
5. Executes: send_email (to customer)
6. Traces: Logs action in CRM
All within single conversation, no manual handoff
Supported Application Categories
CRM & Sales:
- Salesforce, HubSpot, Pipedrive, Dynamics
Spreadsheets & Data:
- Google Sheets, Excel, Airtable
Communication:
- Email (Gmail, Outlook), Slack, Teams
Project Management:
- Asana, Monday, Jira, Trello
Finance & Accounting:
- Stripe, QuickBooks, Wave
Databases:
- MySQL, PostgreSQL, MongoDB (via Zapier integrations)
Time & Scheduling:
- Google Calendar, Outlook Calendar
Collaboration:
- Notion, Confluence, Google Drive
Thousands More:
- E-commerce, support, HR, marketing, and vertical-specific tools
Competitive Positioning
vs. LeanMCP
- Zapier MCP: 8,000+ pre-built connectors, no-code configuration
- LeanMCP: Custom MCP building, full control, lightweight framework
Complementary, not competitive: LeanMCP for custom tools, Zapier for existing apps
vs. Direct API Integration
- Zapier MCP: Standardized protocol, no custom code
- Direct APIs: More control, custom logic, more engineering
vs. Traditional iPaaS (Zapier Zaps)
- Traditional Zaps: Workflow automation (user-initiated or scheduled)
- Zapier MCP: Real-time agent actions via chat/code
Complementary: Traditional Zaps for automation, MCP for agent tool access
Use Cases
Customer Support:
- Agents answer questions + create tickets + escalate to humans
- Access CRM context, knowledge base, ticketing system
Sales Enablement:
- Agents help reps find customer data, create proposals, send updates
- Access CRM, doc generation, email
Operations:
- Agents coordinate across systems (HR, Finance, Procurement)
- Execute actions requiring cross-system context
Engineering Support:
- Agents access deployment tools, monitoring, incident management
- Trigger deployments, update status, notify teams
Customer Success:
- Agents help with onboarding, renewals, support
- Access customer data, send communications, create tickets
Integration Methods
Hosted Cloud (Default)
- LeanMCP hosts Zapier MCP server
- No infrastructure needed
- Immediate access to 8,000+ apps
Self-Hosted (Advanced)
- Run Zapier MCP on own infrastructure
- Full control
- Custom deployments
Advantages
✓ Breadth: 8,000+ apps (vs. 100 for managed platforms)
✓ No-code: Set up in minutes, no engineering needed
✓ Real-time: Agent-driven actions, not batch workflows
✓ Standardized: MCP protocol (not vendor-specific)
✓ Immediately useful: Pre-built connectors (vs. custom integration)
Limitations
✗ Less control: Pre-built connectors, not custom logic
✗ Deeper integration: Not ideal for complex business logic
✗ Latency: Cloud-hosted (slight delay vs. direct API)
✗ Custom tools: Zapier doesn’t build custom integrations
Strategic Position in Agent Stack
Direct API Integration ← → Zapier MCP ← → LeanMCP ← → Custom Tools
(Full control) (Pre-built, easy) (Framework) (Complete custom)
Zapier MCP is the “80/20 solution”: 80% of enterprise tool access needs via 20% of engineering effort.
Market Context
As agents become mainstream, the infrastructure for agent tool access becomes critical. Zapier is leveraging its 20-year history of pre-built connectors to position itself as the agent tools platform—similar to how OpenAI Frontier uses decision traces.
The thesis: Agents need access to 8,000+ business tools, and Zapier’s connectors are the fastest way to enable that.
