multilspy

Why we included this project

multilspy is a Python library that wraps the Language Server Protocol, so you can pull static-analysis results like type-aware completions, symbol definitions, references, and hover signatures from language servers without writing your own JSON-RPC client. It handles the fiddly setup work: downloading the right server binary for your platform, starting and stopping the server, and passing the per-language configuration, which keeps your application code focused on what it wants to do with the analysis. Teams building code-completion features or repository-aware tooling, and researchers prototyping code generation with LLMs, will find it a practical foundation. The library grew out of Microsoft's Monitor-Guided Decoding work, where static analysis steers LLM output, a good hint at the kind of applications it was designed for. Both sync and asyncio APIs are available, and it supports a range of language servers, so it drops into an existing Python project without much friction.
