Install

claude mcp add libofcongress-mcp-server -- npx -y @cyanheads/[email protected]

Requires: LOC_USER_AGENT, LOC_REQUEST_DELAY_MS, MCP_LOG_LEVEL

Our take

This server exposes Library of Congress collections, Chronicling America OCR newspaper archives, and LC subject headings through MCP. It is for researchers, historians, librarians, and retrieval workflows that need primary-source discovery rather than general web search. The use case is clear and credible, but the small footprint suggests a niche utility whose maintenance depth and edge-case handling should be checked before heavier dependence.
