This server provides a range of tools for LLM agents to understand, analyze and interact with Lean projects.\n\n## Key Features\n\n* **Rich Lean Interaction**: Access diagnostics, goal states, term information, hover documentation and more.\n* **External Search Tools**: Use `LeanSearch`, `Loogle`, `Lean Finder`, `Lean Hammer` and `Lean State Search` to find relevant theorems and definitions.\n* **Easy Setup**: Simple configuration for various clients, including VSCode, Cursor and Claude Code.\n\n## Setup\n\n### Overview\n\n1. Install [uv](https://docs.astral.sh/uv/getting-started/installation/), a Python package manager.\n2. Make sure your Lean project builds quickly by running `lake build` manually.\n3. Configure your IDE/Setup\n4. (Optional, highly recommended) Install [ripgrep](https://github.com/BurntSushi/ripgrep?tab=readme-ov-file#installation) (`rg`) to reduce hallucinations using local search.\n\n### 1. Install uv\n\n[Install uv](https://docs.astral.sh/uv/getting-started/installation/) for your system. On Linux/MacOS: `curl -LsSf https://astral.sh/uv/install.sh | sh`\n\n### 2. Run `lake build`\n\n`lean-lsp-mcp` will run `lake serve` in the project root to u…","publisher":null,"homepage":null,"repository":"https://github.com/oOo0oOo/lean-lsp-mcp","version":"0.20.0","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:iflow-mcp_ooo0ooo-lean-lsp-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi"}},"derived":{"capabilities":[{"slug":"code.documentation","name":"Code Documentation","confidence":0.848,"provenance":"derived"},{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":0.768,"provenance":"derived"}],"categories":["code","dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"iflow-mcp_ooo0ooo-lean-lsp-mcp","registry":"pypi","observedAt":"2026-11-09T10:23:14.969Z","publishedAt":"2026-02-12T09:36:23.831761Z","latestVersion":"0.20.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"iflow-mcp_ooo0ooo-lean-lsp-mcp","url":"https://pypi.org/project/iflow-mcp_ooo0ooo-lean-lsp-mcp/","firstSeenAt":"2026-09-09T20:24:43.651Z","fetchedAt":"2026-11-09T10:21:24.792Z","normalizedAt":"2026-11-09T10:21:24.792Z"}]},"firstSeenAt":"2026-09-09T20:24:43.651Z","updatedAt":"2026-11-09T10:23:14.969Z"}
