Patch File MCP

MCPOpen SourceMIT18.0

by PyneSys • Tools & CLI

A microservice that applies precise block-format patches to files in allowed directories, designed for AI agents to make safe, targeted edits.

Example Use Cases

1
Make precise code edits without replacing entire files, by targeting exact text blocks.
2
Apply multiple independent changes to the same file atomically in a single request.
3
Safe file modifications restricted to specified project directories with clear error reporting.

Description

Patch File MCP updates files by applying SEARCH/REPLACE blocks (with <<<<<<< SEARCH / ======= / >>>>>>> REPLACE markers), allowing multiple patches in a single operation. It enforces safety by requiring each search text to appear exactly once and restricting operations to configured allowed directories. The server integrates with MCP clients (e.g., Claude Desktop, Cursor) and reports detailed errors when patches cannot be applied. Useful for making surgical changes to code or text files without rewriting entire files.

patch_file

Update the file by applying a patch/edit to it using block format. Required format: ``` <<<<<<< SEARCH Text to find in the file ======= Text to replace it with >>>>>>> REPLACE ``` You can include multiple search-replace blocks in a single request: ``` <<<<<<< SEARCH First text to find ======= First replacement >>>>>>> REPLACE <<<<<<< SEARCH Second text to find ======= Second replacement >>>>>>> REPLACE ``` This tool verifies that each search text appears exactly once in the file to ensure the correct section is modified. If a search text appears multiple times or isn't found, it will report an error.
