How to Use the Zapier MCP in Pydantic AI

Q: How do I check if my Zapier account is set up correctly with Pydantic AI?

Use getprofile first. This retrieves the user details, which your agent then validates against a Pydantic model. If the data structure is wrong, your agent fails immediately, saving you from bad automation runs.

Q: If I need to audit my past actions with Zapier and Pydantic AI, what should I use?

The gethistory tool retrieves the execution log. Your agent reads this history, then validates the structure of each record using Pydantic models before acting on it.

Q: What's the best way to find existing Zapier workflows with Pydantic AI?

You should use listzaps and then getzap. Listing gives you all names, and getting the individual Zap configuration gives you the structured data your agent needs for guaranteed type safety.

Q: How does Pydantic AI handle complex integrations with Zapier?

By using tools like listapps, the server reports all connected apps. Your agents read this list, and because every response is validated against a schema, you are certain that the app names and connection statuses are correct.

Retrieve workflow settings with `get_zap`

You call the `get_zap` tool to pull all the configuration details for a specific Zap. Because your agents validate every response using Pydantic, you'll get guaranteed, typed data—no unexpected fields or silent corruption. This is vital when building critical production systems; if the API sends bad data, your agent fails loudly, and you know exactly why.

Get user details with `get_profile`

The tool `get_profile` pulls detailed information about the authenticated Zapier user. Your agents use this to confirm permissions or gather necessary identity context before running any workflow. It ensures that every action your agent takes is tied back to a verified, accurate set of user data.

Discover template ideas with `search_templates`

`search_templates` lets the AI client search for pre-made workflow patterns (like 'Trello to Slack'). The result is a clean query string that your agent can reliably parse and use. This capability means you don't just get ideas; you get structured data pointing toward working solutions, which Pydantic validates immediately.

Setup guide

Set up Zapier MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "zapier-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Zapier tools.",
)

result = await agent.run("List recent Zapier transactions")
print(result.output)
