Compatible with every major AI agent and IDE
What is the National Archives Catalog MCP Server?
Connect to the National Archives Catalog (NARA) and explore the history of the United States through natural conversation. This MCP server allows your AI agent to act as a specialized research assistant, retrieving historical data, metadata, and digital objects from one of the world's largest archival collections.
What you can do
- Deep Search — Query records by text, tags, comments, or transcriptions to find specific historical context and documents.
- Record Hierarchy — Navigate complex archival structures by retrieving immediate children of specific parent records (NaId).
- User Contributions — Manage and search through tags, comments, and transcriptions provided by the citizen archivist community.
- Metadata Retrieval — Get detailed information, status metrics, and descriptions for specific National Archives Identifiers.
- Tagging & Interaction — Create or delete tags and comments to organize research findings directly within the catalog ecosystem.
How it works
- Subscribe to this server
- Enter your NARA API Key
- Start researching history from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Historians & Researchers — instantly retrieve primary source documents and metadata without manual catalog navigation.
- Educators — find relevant historical photos and records to build curriculum materials directly from a chat interface.
- Genealogists — search through millions of records and transcriptions to find family history data and archival links.

Frequently asked questions
Can I search for records specifically by the text in their transcriptions?
Yes. Use the search_records_by_transcription tool. This is particularly useful for handwritten documents that have been digitized and transcribed by volunteers.
How do I see the individual items within a larger archival series?
Use the get_record_children tool with the parent NaId. This will list the immediate sub-records or files contained within that specific collection or series.
Can I contribute to the archives by adding tags via the AI?
Yes, the create_tag tool allows you to add descriptive tags to a record using its National Archives Identifier (NaId), helping improve searchability for the community.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
