Validate pageviews at runtime using Pydantic AI

This Fathom Analytics MCP Server integrates with your type-safe agents to fetch visitor trends using `get_visitors` and `get_pageviews` without risk of silent data corruption. Pydantic AI enforces strict schemas on the incoming Fathom API response, ensuring your agent never processes malformed metrics. If the Fathom API structure changes or returns unexpected null values, the Pydantic AI framework raises a validation error immediately. This structural guarantee prevents downstream Pydantic AI automation scripts from failing silently when calculating key performance indicators.

Track custom conversion goals safely with an MCP Server

The `get_event` tool retrieves detailed metrics for specific conversion milestones, while `list_events` lists all custom goals configured on your Fathom site. Your Pydantic AI agent uses these tools to verify that marketing pixels are firing and recording conversions accurately. Because Pydantic AI is model-agnostic, you can use these Fathom tools with Anthropic, OpenAI, or local models. The Pydantic AI framework guarantees that whichever model you choose, the event tracking data matches your exact Python type definitions.

Audit site portfolios and traffic sources

The `list_sites` tool fetches all domains in your account, and `get_referrers` identifies where those Fathom sites get their traffic. Your Pydantic AI agent calls these tools to build automated reports on domain performance, identifying which sites need marketing support. The Pydantic AI runtime validation ensures that Fathom site IDs and referrer strings are properly formatted before your code acts on them. This makes your reporting scripts resilient enough to run in production environments without constant human supervision.

Setup guide

Set up Fathom Analytics 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": {
        "fathom-analytics-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Fathom Analytics MCP in Pydantic AI

Install the package using `pip install "pydantic-ai-slim[mcp]"` and instantiate `MCPToolset` with your Vinkius HTTP URL. Pass this toolset directly to your `Agent` constructor to register the tools.

The framework validates all Fathom Analytics API responses against strict Python types at runtime. This prevents your agent from hallucinating metrics or failing due to unexpected data structures.

Yes. The framework is model-agnostic, allowing your agent to query tools like `get_current_visitors` or `get_top_pages` using local models or commercial APIs.

Vinkius hosts and manages the server externally. You only need to run your Pydantic AI script and point your `MCPToolset` to the provided Vinkius MCP endpoint.

The integration only queries anonymous aggregates, such as total pageview counts and device distributions, never touching raw visitor IP-hashes. Pydantic AI validates these clean data schemas, while Vinkius handles the API token securely in an ephemeral V8 sandbox.
