CodeSavant is a WIP project.
CodeSavant is a Model Context Protocol (MCP) server that provides code manipulation, execution, and version control capabilities. It allows AI assistants to read, write, and execute code while maintaining a history of changes.
- Read and write code files with line-specific operations
- Execute code in multiple programming languages (Python, Node.js)
- Execute shell commands in a controlled environment
- Track and manage code changes with version control
- Search within code files
- Revert to previous versions of code
- Clone the repository:
git clone https://github.com/twolven/mcp-codesavant.git
cd mcp-codesavant- Install the required dependencies:
pip install -r requirements.txt- Add the server configuration to your Claude Desktop config.json:
{
"mcpServers": {
"codesavant": {
"command": "python",
"args": ["path/to/codesavant.py"]
}
}
}The server creates and manages the following directory structure:
workspaces/
├── project1/
│ ├── .code_history.json
│ └── [code files]
├── project2/
│ ├── .code_history.json
│ └── [code files]
└── ...
Read contents of a code file, optionally searching for specific sections.
{
"project": "string", // Project name
"path": "string", // Path to file relative to project workspace
"search": "string" // (Optional) Text/pattern to search for in file
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"content": "string", // File content
"start_line": number, // (Only if search used) Starting line of found section
"end_line": number // (Only if search used) Ending line of found section
}
}Write or update specific lines in a code file.
{
"project": "string", // Project name
"path": "string", // Path to file relative to workspace
"content": "string", // Content to write (just the lines being changed)
"start_line": number, // Starting line number for the change
"end_line": number // (Optional) Ending line number for the change
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"diff": {
"changes": [ // List of changes made
[string, number, number, number, number] // (type, old_start, old_end, new_start, new_end)
],
"timestamp": number // When the change was made
}
}
}Get change history for a code file.
{
"path": "string" // Path to file relative to workspace
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"history": [
{
"changes": [ // List of changes made
[string, number, number, number, number]
],
"timestamp": number
}
]
}
}Execute a code-related shell command.
{
"command": "string", // Shell command to execute
"timeout": number // (Optional) Command timeout in seconds (default: 30)
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"state": "success|error|timeout|cancelled",
"output": "string", // Command output
"error": "string", // Error message if any
"runtime": number, // Execution time in seconds
"exit_code": number // Command exit code
}
}Execute code in specified language.
{
"code": "string", // Code to execute
"language": "string", // Programming language ("python" or "node")
"timeout": number // (Optional) Execution timeout in seconds (default: 30)
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"state": "success|error|timeout|cancelled",
"output": "string", // Code execution output
"error": "string", // Error message if any
"runtime": number, // Execution time in seconds
"exit_code": number // Execution exit code
}
}Revert a code file to a specific version.
{
"path": "string", // Path to file relative to workspace
"timestamp": number // Timestamp of version to revert to
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"diff": {
"changes": [ // List of changes made
[string, number, number, number, number]
],
"timestamp": number // When the reversion was made
}
}
}Read specific lines from a code file.
{
"project": "string", // Project name
"path": "string", // Path to file relative to project workspace
"start_line": number, // Starting line number to read
"end_line": number // (Optional) Ending line number to read
}Response:
{
"success": true,
"timestamp": 1234567890,
"data": {
"content": "string" // Content of the specified lines
}
}The server provides detailed error responses in the following format:
{
"success": false,
"timestamp": 1234567890,
"data": null,
"error": "Error message"
}Error types include:
CodeFileError: File operation errorsCodeValidationError: Code validation errorsCodeExecutionError: Code execution errors
Currently supported languages for code execution:
- Python (using system Python interpreter)
- Node.js (using node command)
Each language execution creates a temporary file in the workspace directory and executes it with appropriate interpreter.
