How to Set Up and Use Ultimate Coder
UltimateCoder MCP is a local-first Python MCP server built on FastMCP that gives AI assistants complete filesystem and terminal control over the developer's machine, including shell command execution, process management, precise file editing, unified diff patching, batch file processing, and ripgrep-powered code search. All operations run entirely locally—no data leaves the machine—making it suitable for sensitive codebases and enterprise environments. Developers who want to give Claude or another AI assistant deep, programmatic access to their local development environment can use this server as a powerful co-pilot for refactoring, automation, and codebase exploration.
Prerequisites
- Python 3.8 or higher
- fastmcp installed (pip install fastmcp) — the core dependency
- ripgrep installed on the system for the code search tool
- flake8 and pylint installed for Python linting tools
- An MCP-compatible client such as Claude Desktop
Clone the repository
Download the UltimateCoder MCP source code to your local machine.
git clone https://github.com/m-ahmed-elbeskeri/UltimateCoderMCP.git
cd UltimateCoderMCPInstall dependencies
Install the Python dependencies including fastmcp. Optionally install ripgrep, flake8, and pylint for full tool support.
pip install fastmcp
# Optional but recommended
pip install flake8 pylint
brew install ripgrep # macOS
# apt install ripgrep # LinuxStart the server
Run the server locally. It starts a stdio-based MCP server ready to accept connections from an MCP client.
python main.pyConfigure your MCP client
Add UltimateCoder to your Claude Desktop configuration file, pointing to the Python executable and main.py with the absolute path to the repository.
Use the AI assistant to control your local environment
The server exposes 21 tools including tool_run_command, tool_read_file, tool_write_file, tool_replace_block, tool_apply_patch, tool_search_code, tool_lint_python, tool_static_analysis_python, tool_process_files, and tool_kill_process.
Ultimate Coder Examples
Client configuration
Add UltimateCoder MCP to claude_desktop_config.json using Python to run main.py from the cloned repository directory.
{
"mcpServers": {
"ultimatecodermcp": {
"command": "python",
"args": ["/absolute/path/to/UltimateCoderMCP/main.py"]
}
}
}Prompts to try
Example prompts that exercise the filesystem, shell, and code analysis tools.
- "Search all Python files in /my/project for usages of the deprecated 'requests.get' call"
- "Apply this unified diff patch to /my/project/src/main.py"
- "Run the test suite with 'pytest /my/project/tests' and show me the failures"
- "Lint all Python files in /my/project/src and list the flake8 errors by file"
- "List all processes currently running and kill the one using port 8080"Troubleshooting Ultimate Coder
tool_search_code fails with ripgrep not found error
Install ripgrep on your system. On macOS run 'brew install ripgrep', on Debian/Ubuntu run 'apt install ripgrep'. The tool falls back gracefully for some searches but ripgrep is required for full recursive search functionality.
tool_apply_patch rejects a diff with context mismatch errors
The patch engine uses strict context matching — the surrounding lines in the diff must exactly match the file on disk. Regenerate the unified diff from the current file state (e.g., with 'git diff' or 'diff -u') rather than using a stale or hand-edited patch.
The server does not appear as a tool in Claude Desktop
Verify the absolute path to main.py in the config is correct and that the Python interpreter listed can import fastmcp. Test by running 'python /absolute/path/to/UltimateCoderMCP/main.py' in your terminal — it should start without errors before Claude Desktop can connect to it.
