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.
Part of the ellmos MCP family:
| Server | Focus | npm |
|---|---|---|
| ellmos-filecommander-mcp | Filesystem operations, process management, interactive sessions | ellmos-filecommander-mcp |
| ellmos-codecommander-mcp | Code analysis, AST parsing, import management | ellmos-codecommander-mcp |
| ellmos-clatcher-mcp | Utility tools: repair, convert, detect, batch ops | ellmos-clatcher-mcp |
Each server covers a different domain. Use one, two, or all three depending on your workflow.
| Tool | Description |
|---|---|
fix_json |
Repair broken JSON: strip comments, trailing commas, single quotes, BOM/NUL |
fix_encoding |
Fix encoding issues: BOM removal, double-encoded UTF-8, cp1252 artifacts |
fix_umlauts |
Fix broken German umlauts from double-encoding (e.g. ä -> ä) |
convert_format |
Convert between JSON, YAML, TOML, XML, CSV, and INI |
detect_dupes |
Find duplicate files by content hash (SHA256), grouped by identical content |
folder_diff |
Compare two directories, or take a snapshot and diff on next call |
batch_rename |
Rename files using regex patterns, with dry-run preview |
archive |
Create, extract, or list ZIP archives |
checksum |
Calculate file hashes (SHA256, MD5, SHA1, SHA512) with optional verification |
cleanup_file |
Remove BOM, trailing whitespace, fix line endings, strip NUL bytes |
scan_emoji |
Find emoji characters in code files |
regex_test |
Test regex patterns against text, showing all matches with groups |
All destructive tools default to dry-run mode and require explicit dry_run: false to write changes.
