FAQ from LSP Tools MCP Server

What does LSP Tools MCP Server provide?

It provides two tools: find_regex_position to locate regex matches (with line and column positions) and list_allowed_directories to show the allowed directories.

How does the server restrict file access?

Access is restricted to directories specified as command‑line arguments when starting the server (e.g., node dist/index.js /path/to/dir). The server will not operate on files outside those paths.

What dependencies are required to run the server?

Node.js and npm are required. The package uses Jest for testing and ESLint for linting, but these are development dependencies; only the built server is needed for production use.
