How to Use the Internet Archive Metadata MCP in Pydantic AI

Q: How does Pydantic AI validate Internet Archive Metadata responses?

When your agent calls a tool like getmetadata, the MCP Server response is parsed directly into your Pydantic models. Any missing or malformed fields trigger a validation error.

Use Pydantic AI with Internet Archive Metadata for type-safe, validated data ingestion that never hallucinates fields.

Type-safe metadata validation

Every response from `get_metadata` is validated against your Pydantic models at runtime. If the archive structure changes, your agent fails immediately rather than processing bad data. This prevents silent corruption in your archival pipeline. You define the schema, and the MCP Server enforces it during every call.

Track item evolution with history tools

Your agent uses `get_history` to log changes in item records over time. It keeps a precise audit trail of how metadata has been updated. This allows for rigorous verification of archival records. Your Pydantic models capture the full history of an item's modifications.

Categorize items with collection tools

Your agent invokes `get_collections` to categorize incoming items into your local taxonomy. It ensures every piece of data is placed in the correct bucket. This maintains order in your digital repository. Your agent uses these tags to trigger downstream, type-safe logic.

Setup guide

Set up Internet Archive Metadata 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": {
        "internet-archive-metadata-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Internet Archive Metadata transactions")
print(result.output)
