🤖 TypeMill

Pure Rust MCP server bridging Language Server Protocol (LSP) to AI coding assistants.

TypeMill gives your AI assistant (Claude, Cursor, etc.) direct access to language server intelligence. It enables safe refactoring, precise code navigation, and workspace-aware operations across TypeScript, Rust, and Python projects.

✨ Key Features

• 🛡️ Safe Refactoring - Unified dry-run API with automatic rollback protection. Preview changes before execution.
• 🧠 Native Intelligence - Leverages industry-standard LSP servers (rust-analyzer, tsserver) for 100% accurate symbol resolution.
• ⚡ Rust Performance - Built for speed with zero-cost abstractions and async I/O.
• 🔄 Auto-Updates - Automatically handles imports, cross-file references, and self-references during moves and renames.
• 🔌 Tooling Depth - Comprehensive suite for navigation (inspect_code), search (search_code), and refactoring (rename_all, relocate).

🚀 Quick Start

1. Install

curl -fsSL https://raw.githubusercontent.com/goobits/mill/main/install.sh | bash

Alternatively: cargo install mill --locked

2. Setup

Run in your project root to auto-detect languages and install necessary LSP servers:

mill setup

3. Connect

Add to your MCP configuration (e.g., Claude Desktop):

{
  "mcpServers": {
    "mill": {
      "command": "mill",
      "args": ["start"]
    }
  }
}
