retrieval-mcp 0.1.0

Installable MCP server for the Retrieval academic-paper search + ACE journal + index inventory API

retrieval-mcp

An MCP server for the Retrieval academic-paper API — semantic paper search, document matching, ACE journal memory, and index inventory. Self-contained: it talks to the backend over HTTP only (just mcp + httpx), so it installs anywhere with uvx / pip — no repo checkout, no GPU, no models.

By default it targets the compute box on the lab LAN (http://10.100.100.111:8000), which trusts LAN callers so no key is needed. Off-LAN, point RETRIEVAL_API_URL at the public gateway (https://retrieval.rnarket.com) and set RETRIEVAL_API_KEY (sk-...).

Tools

Tool	What it does
search_papers	Semantic hybrid search over 95k+ top-venue CS papers
search_within_paper	Every matching passage inside one paper
match_document / match_paper	Content-nearest papers to a passage / a paper
list_conferences / corpus_stats	Venue registry / corpus size
journal_record / journal_search / journal_recent	ACE journal work-memory (cwd-scoped)
index_inventory	Your indexed-file tree: user → host → project → dir → file
