  • Provides code linting capabilities through ESLint integration, allowing for static code analysis according to configurable rules

  • Integrates with Jest for running and managing tests, enabling test execution and monitoring during development

  • Uses npm for package management, installation of dependencies, and running build and development scripts

LSP Tools MCP Server

A Model Context Protocol (MCP) server providing Language Server Protocol-like functionality for text analysis.

Features

  • Find Regex Position: Find the 0-indexed line and column positions of regex pattern matches in a file
  • List Allowed Directories: Get a list of directories the server is allowed to access

Installation

npm install npm run build

Usage

# Start the server allowing access to a specific directory node dist/index.js /path/to/allowed/directory # Start the server with multiple allowed directories node dist/index.js /path/to/dir1 /path/to/dir2 /path/to/dir3

Development

Running Tests

The project uses Jest for testing. Run the tests with:

npm test

To run tests in watch mode during development:

npm run test:watch

Linting

Lint the code with ESLint:

npm run lint
