How to Use the Vercel MCP in Pydantic AI

Q: How does Pydantic AI handle Vercel deployments?

The agent uses createverceldeployment and deleteverceldeployment. If the API response for a deployment ID isn't structured correctly, your agent won't proceed. That validation is its core value.

Q: What data types does Pydantic AI read from Vercel?

It primarily handles environment variable data through listvercelprojectenvvars. The type system ensures that every key and value returned are predictable strings or basic types.

Q: Can I use Pydantic AI to check Vercel teams?

Yes. While listing teams with listvercelteams is possible, the real benefit is that any data received—like a list of team names or IDs—is immediately validated against your Python model.

Q: Does Pydantic AI help check Vercel account domains?

You can use listvercelaccountdomains. The framework validates this data, meaning you'll get a list of strings that actually look like valid domain names.

Ensure zero runtime errors. Pydantic AI makes Vercel interactions type-safe and verifiable.

Manage Vercel Deployments with the MCP Server

When your agent uses `create_vercel_deployment`, it knows exactly what to expect back, or else it fails loudly. You can also review a build's history using `list_vercel_deployments`. The type checking makes this reliable.

Verify Vercel Project Settings with the MCP Server

Need to check project details? `get_vercel_project_details` returns a structured object that Pydantic validates at runtime. Similarly, listing environments via `list_vercel_project_env_vars` guarantees correct field names.

List and Check Vercel Account Scope using MCP Server

The server lets your agent list projects with `list_vercel_projects`, ensuring every item returned matches the expected schema. Checking user info with `get_vercel_user_profile` is also fully typed.

Setup guide

Set up Vercel 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": {
        "vercel-extended-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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