01 · Install Lacuna Research MCP

Claude Code

claude mcp add tiptreesystems-lacuna-research-mcp -- uvx lacuna-research-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "tiptreesystems-lacuna-research-mcp": {
      "command": "uvx",
      "args": [
        "lacuna-research-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-19 - young repo, little track record yet

license MIT - declared in the repository

pypi package lacuna-research-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.tiptreesystems is GitHub-verified and matches the repo owner

03 · What Lacuna Research MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

- get_paper and get_direction default to view="context". These context views request Lacuna's compact agent-oriented payloads by default to keep MCP responses small. Paper context includes summary_markdown when available (otherwise abstract), authors, and figures; direction context includes summary_markdown, capped papers/authors/related directions, and truncation markers. Use view="full" when you need the raw metada
