Lacuna Research MCP: hosted MCP server for ML literature and research directions

Tiptree Systems built Lacuna Research MCP around Lacuna, a heterogeneous research map linking papers, research directions, authors, venues, institutions, and generated research proposals, each with a provenance trail back to its originating paper. The server exposes five tool families: generated research proposals, concept-cluster navigation, agent-ready literature search in markdown with source links, researcher intelligence (authors, publication history, impact), and landscape mapping across venues and institutions. Who it is for It targets coding agents such as Codex and Claude Code, plus editor integrations in Cursor and VS Code and the Claude custom connector. The install path is intentionally shallow: the hosted endpoint https://lacuna.tiptreesystems.com/api/mcp serves all clients without a local Python dependency or Lacuna account, and the repo ships an Agent Plugin for Cursor alongside manual JSON configs for both editors.
