Ellmos Clatcher MCP server

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.

[!NOTE]

AI / LLM Integration Note: All destructive operations (e.g. batchrename, cleanupfile, fixjson, fixencoding, fixumlauts) default to dry-run mode (dryrun: true). Autonomous agents must explicitly specify dry_run: false to execute mutations on disk.

Highlights & Value Proposition

• 12 Specialized Agent Tools: Extends Claude Code, Cursor, and MCP agents with utilities they lack out-of-the-box (JSON repair, encoding normalization, format conversion, diffing, deduplication, regex batch renaming).
• Default Dry-Run Guard: Mutating tools run in preview mode (dryrun: true) by default. Agents must pass dryrun: false to write to disk.
• 100% Local-First & Zero-Egress: Pure local execution over stdio JSON-RPC. No network calls, no cloud telemetry, zero remote attack surface.
• Atomic File Operations: All disk modifications write to temporary staging buffers before replacement, preventing corrupt or truncated files.
• Lossless Encoding Preservation: Eliminates Windows cp1252 artifacts, BOM headers, and German umlaut Mojibake (ä, ö, ü, ß) while guaranteeing pristine UTF-8 bytes.
• Universal Multi-OS Parity: Tested continuously across Ubuntu, Windows, and macOS with native path handling and line endings.
