Patchloom MCP Server

One binary. Every platform. Structured file edits for AI agents. Patchloom is a single-binary CLI that gives AI coding agents safe, structured file editing on any operating system. It edits JSON, YAML, and TOML by selector (not regex), preserves comments, understands code structure across 20 languages, batches multiple file edits into one tool call, and works identically on Linux, macOS, and Windows.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
