What is the Library of Congress MCP Server?
Connect your AI agent to the Library of Congress (LOC) and explore the vast digital archives of the United States' oldest federal cultural institution. Access millions of records, from historical newspapers to rare maps and sound recordings.
What you can do
- Global Search — Search across the entire LOC catalog including items, legislation, and blogs using the
searchtool. - Digital Collections — Browse and list all available digital collections or drill down into specific ones like the 'Abraham Lincoln Papers' using
list_collectionsandget_collection_items. - Format-Specific Discovery — Filter your research by specific media types such as maps, audio, or photos with
search_format. - Deep Bibliographic Research — Retrieve detailed metadata and digital resource links for specific items using
get_item. - OCR & Text Analysis — Access full-text OCR, word coordinates, and context snippets for digitized documents via
get_text_service. - Technical Image Metadata — Fetch IIIF technical data for high-resolution images using
get_image_info.
How it works
- Subscribe to this server
- Enter your Library of Congress API Key (optional but recommended for higher rate limits)
- Start researching historical data directly from your MCP-compatible client
Who is this for?
- Researchers & Historians — Instantly find primary sources and bibliographic data without manual catalog navigation.
- Educators & Students — Access digitized manuscripts and historical records for curriculum development.
- Data Scientists — Utilize OCR services and metadata for large-scale historical text analysis.
Built-in capabilities (8)

How Vinkius secures
Library of Congress for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the Library of Congress MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I search for items specifically in a format like 'maps' or 'audio'?
Yes! Use the search_format tool and specify the format parameter (e.g., 'maps', 'photos', 'audio') along with your query to get targeted results.
How do I get the full OCR text of a digitized document?
You can use the get_text_service tool. Provide the document segment path and set the full_text parameter to 1 to retrieve the complete OCR transcript.
Can I list items from a specific collection like the Abraham Lincoln papers?
Yes. Use the get_collection_items tool with the collection slug (e.g., 'abraham-lincoln-papers') to see all items contained within that specific archive.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
