@shxiaj/everything-mcp

MCP (Model Context Protocol) server for Everything — the lightning-fast Windows file search engine.

Forked and extended from everythingsdk-mcp.

Uses ffi-rs to call the Everything SDK natively and @modelcontextprotocol/sdk for the MCP server protocol.

Features

• Dual SDK support — Auto-detects Everything 1.5 (SDK v3) or 1.4 (SDK v2)

• Lightning-fast file search — Leverage Everything's native search capabilities

• Multiple tools — Search, version check, status, and file info

• Flexible configuration — Environment variable overrides for SDK paths

SDK Architecture

src/
├── index.ts              # MCP server entry point (tools, request handlers)
├── everything-client.ts  # EverythingClient + SdkProvider abstraction
├── ffi-bindings.ts       # Raw FFI bindings to Everything3_*.dll (SDK v3, Everything 1.5)
└── ffi-bindings-v14.ts   # Raw FFI bindings to Everything*.dll (SDK v2, Everything 1.4)

EverythingClient auto-detects the SDK version: tries v3 first, falls back to v2. Override with EVERYTHING_SDK_VERSION=v2 or v3 env var.

SDK v3 (Everything 1.5) vs SDK v2 (Everything 1.4)
