How to Use the Library of Congress MCP in AutoGen

Q: How do AutoGen agents collaborate to search the Library of Congress?

One agent can run a broad search using search, while a second agent uses searchformat to filter the results. They pass findings back and forth in a conversation loop until they locate the target item.

Q: Can an AutoGen agent verify Library of Congress OCR text accuracy using this MCP Server?

Yes, an agent can call gettextservice to fetch raw OCR snippets. Another agent can then compare this text with bibliographic details fetched via getitem to flag historical anomalies.

Q: How do I register Library of Congress tools with an AutoGen AssistantAgent?

Use the mcpservertools helper to fetch the tools from the MCP Server endpoint. Pass the resulting list directly to your AutoGen AssistantAgent constructor, which automatically maps the schemas.

Deploy AutoGen multi-agent teams to debate and verify historical facts using the Library of Congress archive.

Perplexity

Multi-agent debate on archival provenance

The `get_item` tool retrieves detailed bibliographic data for any single historical record. In an AutoGen setup, a research agent pulls this metadata while a critic agent analyzes it for historical consistency. The critic agent can demand further verification, prompting the researcher to call `get_resource` to inspect specific digitized files. This multi-agent debate ensures your historical conclusions are backed by verified records.

Collaborative search and format filtering

The `search` tool allows your primary AutoGen agent to execute broad keyword queries across the entire archive. When the search returns too many results, a filtering agent steps in to narrow the scope. This filtering agent calls `search_format` to isolate specific media types like maps or audio files. The agents negotiate until they find the exact historical assets that match your project's criteria.

Automated OCR transcription verification

The `get_text_service` tool accesses raw OCR text and context snippets from historical documents using this MCP Server. Your AutoGen transcription agent pulls this raw text to analyze historical terminology. Meanwhile, a coordination agent cross-references these snippets with collection lists retrieved via `get_collection_items`. This collaborative workflow lets your agents verify transcription context across thousands of pages.

Setup guide

Set up Library of Congress MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes Library of Congress tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="Library of Congress_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Library of Congress data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="Library of Congress_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Library of Congress data")
    print(result.messages[-1].content)
