 A powerful command-line interface for the [**Language Server Agent Protocol (LSAP)**](https://github.com/lsp-client/LSAP). `lsp-cli` provides a bridge between traditional [Language Server Protocol (LSP)](https://microsoft.github.io/language-server-protocol/) servers and high-level agentic workflows, offering structured data access and a robust background server management system.
 
 Built on top of [lsp-client](https://github.com/lsp-client/lsp-client) and [LSAP](https://github.com/lsp-client/LSAP), this tool is designed for developers and AI agents who need reliable, fast, and structured access to language intelligence.
