MCP utility toolkit for JSON repair, encoding fixes, format conversion, duplicate detection, batch rename, ZIP archives, checksums, and regex testing
README
Claude Patcher -- an MCP server that extends AI coding agents with utility tools they don't have natively. File repair, format conversion, duplicate detection, batch operations, and more.
Use Clatcher when your agent needs reliable local maintenance tools for text files, data files, and project folders: repair invalid JSON, normalize encodings, convert formats, compare folders, rename files safely, and verify checksums without leaving the MCP workflow.
