MCP Code Editor

A FastMCP server providing powerful code editing tools including precise file modifications with diff-based operations, file creation and reading with line numbers, and more tools for code editing workflows.

Features

• Precise file modifications with diff-based operations
• File creation and reading with line numbers
• Project analysis and structure inspection
• AST (Abstract Syntax Tree) analysis for Python code
• Console tools for interactive processes
• Library indexing for external dependencies
• Code definition search and navigation
• No automatic backup files (v0.1.10+) - cleaner file operations without .bak files

Installation

pip install mcp-code-editor

Usage

As a standalone server

mcp-code-editor

As a library

from core import DiffBlock, DiffBuilder, FileModifier
from tools import ProjectAnalyzer, ASTAnalyzer

# Create and apply file modifications
modifier = FileModifier("path/to/file.py")
diff_block = DiffBlock(
    old_content="old code",
    new_content="new code",
    start_line=10,
    end_line=15
)
modifier.apply_diff(diff_block)
