Type-safe document retrieval with Pydantic AI

This MCP server exposes `get_document` to let your agent read NoSQL records with strict runtime validation. Pydantic AI validates every returned document against your defined schemas before your agent ever sees it. If the database returns unexpected data, the framework raises a validation error immediately. This prevents silent failures and ensures your agent operates on clean, expected structures.

Schema-validated database writes

This MCP Server uses `set_document` to create or update records in your Firestore collection. Your agent can write state changes or update user data without bypassing your application's type safety rules. Because every input is validated, you don't have to worry about the agent writing corrupt JSON to your database. The write either matches your Pydantic schema or fails before execution.

Safe document deletion

The `delete_document` tool allows your agent to remove records cleanly from your configured collection. This is ideal for managing transient session states or user-requested data purges. The tool returns a clear success or failure status that your agent can handle programmatically. You get predictable, type-safe database cleanup using standard MCP tools.

Setup guide

Set up Google Firestore Collection 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": {
        "google-firestore-collection-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Google Firestore Collection transactions")
print(result.output)
