What it does
An MCP server that integrates ESLint into Claude and other MCP clients. It analyzes JavaScript and TypeScript code by reading project files without requiring external network calls. The README excerpt doesn't detail the implementation, so see the @eslint/mcp package documentation for specifics on which ESLint features are exposed and how results are delivered to the client.
Who it's for
JavaScript and TypeScript developers using Claude Code or other MCP-enabled editors who want linting feedback integrated into their development environment without context switching.
Common use cases
- Check code for linting violations while editing in Claude Code
- Run ESLint analysis on multiple files across a project
- Integrate linting feedback into AI-assisted code review workflows
Setup pitfalls
- Requires read and write access to the filesystem—ensure the server has permissions to scan your project directory
- ESLint configuration files (
.eslintrc,eslint.config.js) must be discoverable in the working directory or parent paths - The package reports zero tools in the capability scan, which is atypical for an MCP server—this may indicate early development or reliance on resources rather than tools; verify current functionality against the official package documentation before production use
