About vscode-mcp

tjx666/vscode-mcp

MCP server for Claude Code/VSCode/Cursor/Windsurf to use editor self functionality. ⚡ Get real-time LSP diagnostics, type information, and code navigation for AI coding agents without waiting for slow tsc/eslint checks.

Exposes eight MCP tools including symbol renaming with automatic import updates, comprehensive LSP information aggregation (definition, hover, signatures), and safe file operations—all backed by VSCode's language servers rather than subprocess execution. Operates as a monorepo with a VSCode extension bridge that maintains per-workspace socket connections to route MCP protocol requests into real-time LSP data, eliminating delays from external type-checking and linting commands. Supports Cursor, Claude Code, Windsurf, and Gemini CLI with granular tool filtering via environment variables or command-line arguments.
