Everything MCP Server

An MCP server for Everything by VoidTools that provides Claude Desktop with lightning-fast filesystem search on Windows. This implementation uses native C bindings via the Everything SDK for maximum performance, with a transparent fallback to the HTTP API.

Features

• Blazing Fast: Leverages the native Everything64.dll for near-instant results.

• Architecture Aware: Automatically detects and loads the correct DLL (32-bit or 64-bit) based on your Node.js runtime.

• Thread Safe: Implements an internal Mutex to prevent race conditions during concurrent tool calls.

• Non-Blocking: Uses asynchronous worker threads for SDK queries to keep the MCP connection responsive.

• Smart Fallback: Automatically switches to the Everything HTTP Server if the SDK is unavailable.
