context-killer-mcp

# Context-Killer MCP A little MCP server that keeps big code generation out of Claude's context window. When Claude writes a large file, every line flows back through the conversation and eats tokens. This server hands the job to Google's Gemini instead: Gemini writes the file straight to disk, and Claude only gets back a one-line "done". The code never lands in the chat. It's a single tool, `delegate_to_gemini_and_save`. You give it a prompt and a path; it optionally reads a few files for context, asks Gemini for the code, and saves it. > Only use this for small taks or if you just want to try it out its not fully polished > and claude doesnt see the results which is good for saving Tokens but it may lead to > Errors since gemini api is not as good in coding and should only be used for small simple Tasks. ## The tool `delegate_to_gemini_and_save(task_prompt, target_file_path, context_files=None)` - `task_prompt` – what you want built, in plain words - `target_file_path` – where to save it (missing folders are created) - `context_files` – optional list of files for Gemini to read first ## Setup You'll need Python 3.11+ and a free Gemini key from <https://aistudio.google.com/app/apikey>. ```bash pip install -r requirements.txt cp .env.example .env # then paste your key into .env ``` ## Use it in Claude Desktop Add this to your `claude_desktop_config.json`: - Windows: `%APPDATA%\Claude\claude_desktop_config.json` - macOS: `~/Library/Application Support/Claude/claude_desktop_config.json` ```json { "mcpServers": { "context-killer": { "command": "python", "args": ["C:\\path\\to\\context-killer-mcp\\server.py"], "env": { "GEMINI_API_KEY": "your-key-here" } } } } ``` Restart Claude, then just ask: *"Use context-killer to write … and save it to …"*. ## Good to know - It writes (and overwrites) files on disk, so glance at what Claude's about to do before approving. - Your prompt and any context files get sent to Gemini — don't point it at secrets. - `.env` is git-ignored. Never commit your real key. ## License MIT — see [LICENSE](LICENSE).
