What is the Lune MCP server?

If you already use Lune, the lune mcp server is the piece that lets your assistant work with it directly. Lune Research MCP server (stdio + Streamable HTTP) proxying api.luneresearch.com.

What the server does

Official Model Context Protocol server for Lune Research.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • search_papers — Hybrid vector + BM25 search across the corpus
  • search_papers_many — Run many query variants in one call, RRF-merged
  • search_related_papers — Semantically nearest papers to a given paper
  • get_paper_fulltext — Parsed full text (markdown or JSON)
  • get_paper_citations — Citation graph (cited_by or cites)
  • list_conferences — Indexed venues, optionally by category
  • get_conference_papers — Paginated papers for a venue
  • extract_from_papers — Structured field extraction across many papers
  • verify_claims — Fact-check claims against the corpus with quotes
  • search_research_guidance — Curated reproducibility / methodology corpus
  • get_research_guidance_doc — Full text of a guidance document
  • list_subscriptions — Active conference subscriptions

Credentials and setup notes

Configuration is passed through the environment: LUNE_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Lune's toolset — search_papers, search_papers_many, search_related_papers and 11 more — is a fair guide to whether it matches your workflow. It is maintained by retrogradelabs; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Lune.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Lune to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (search_papers, search_papers_many, search_related_papers, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Lune directly.
