How to query your research library from Claude Code or Cursor with Polaris

Expose Polaris's read-only tools as an MCP server so coding agents can search your knowledge base.

Short answer: Open Polaris and find the MCP server settings, then check the self-check result; then choose the transport the README lists, Streamable HTTP or stdio, that your agent supports; add the Polaris MCP server to Claude Code, Codex or Cursor using the connection details shown in the app. All steps.

Who it is forA researcher who already works in Claude Code, Codex or Cursor and wants those agents to read their Polaris library while writing code or notes.

The problemSwitching between the research app and a coding agent breaks flow, and the agent cannot see the papers and notes already collected.

The outcomeA coding agent that can search and read your project's papers and wiki pages through the MCP server, without being able to change them.

What you need first

  • A computer where the Polaris desktop app can run (the README says new releases are desktop-only)
  • A model source: an agent you already use, such as Claude Code, Codex or Gemini CLI, or a model API key
  • For experiments: SSH access to a GPU server and your own SSH credentials
  • A research direction or topic you want to explore

Steps

  1. Open Polaris and find the MCP server settings, then check the self-check result.
  2. Choose the transport the README lists, Streamable HTTP or stdio, that your agent supports.
  3. Add the Polaris MCP server to Claude Code, Codex or Cursor using the connection details shown in the app.
  4. Use the try-it playground in Polaris to confirm the tools return results for your project.
  5. Ask your coding agent a question about your library and check the cited wiki pages.

Prompt for your agent

Using the Polaris repo at ZJU-REAL/Polaris, connect the MCP server for project <project name> to <claude-code, codex or cursor>. Expected output: the agent lists papers from that project that match the query <search query>. Verify that the results come only from the chosen project and that no write tool was called.

Caveat. The README says the MCP tools are strictly read-only and project-isolated, so the agent cannot edit your library or experiments through them.
