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` and `Lean Hammer` 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`) for local search and source scanning (`lean_verify` warnings).\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### 1b. Alternative: Install with Nix\n\nIf you use Nix, you can install the package direct…","publisher":null,"homepage":null,"repository":"https://github.com/oOo0oOo/lean-lsp-mcp","version":"0.33.0","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi: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":"lean-lsp-mcp","registry":"pypi","observedAt":"2026-11-09T13:28:45.507Z","publishedAt":"2026-11-03T16:06:44.550269Z","latestVersion":"0.33.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"lean-lsp-mcp","url":"https://pypi.org/project/lean-lsp-mcp/","firstSeenAt":"2026-09-09T23:25:14.204Z","fetchedAt":"2026-11-09T13:26:50.815Z","normalizedAt":"2026-11-09T13:26:50.815Z"}]},"firstSeenAt":"2026-09-09T23:25:14.204Z","updatedAt":"2026-11-09T13:28:45.507Z"}
