Type-Safe Literature Searches

The `search_articles` tool fetches PubMed and Agricola records straight into your application. It returns titles, citations, and DOIs. Pydantic AI ensures the incoming JSON perfectly matches your expected schema. If the database returns a string where an integer should be, the agent fails loudly with a validation error. You never get silent corruption. The MCP Server guarantees your downstream code only processes clean, structured publication data.

Validated Grant Lookups

The `search_grants` tool pulls funding information directly from the Grist API. Your agent retrieves exact award values, agencies, and principal investigators. Every field gets checked at runtime. You can swap between OpenAI, Anthropic, or local models without rewriting your integration. The framework handles the tool execution, while the agent focuses purely on reasoning about the funding records.

Discover Query Schemas with Pydantic AI

The `get_article_fields` tool lists every searchable attribute in the database. Your agent calls this to understand the API's shape before attempting complex Boolean logic. It removes the guesswork from literature mining. You connect this using the unified toolset class. The MCP standard handles the transport, and your agent instantly understands the available search parameters. It builds precise queries that actually return results.

Setup guide

Set up Europe PMC 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": {
        "europe-pmc-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Europe PMC MCP in Pydantic AI

Create an `MCPToolset` instance pointing to your MCP server's HTTP endpoint. Add it to the `toolsets` array when defining your Agent.

Yes. Every response from the tools passes through Pydantic's runtime validation. The agent throws an immediate error if the data shape is wrong.

You can. Pydantic AI is model-agnostic. You run a local LLM and still query the remote literature database through the standard protocol.

The unified toolset supports both Streamable HTTP and SSE transports. Choose whichever fits your network architecture best.

The endpoint processes queries for public life science publications and grant metadata only. Vinkius drops the connection immediately after the tool executes. Your internal Pydantic models and application state remain completely isolated.
