prompt-forge

An MCP server that forges rough prompts into expert, task-tailored prompts — right inside Claude Desktop, Cursor, or any MCP host. No API key, no extra model: it hands your host's own model expert prompt-engineering guidance and lets it do the rewriting.

Tools

• enhance_prompt — rewrite a rough prompt into a polished, structured one. Args: draft (required), target (general | coding | image | writing | research), context (optional).
• critique_prompt — point out a prompt's weaknesses and ask clarifying questions. Args: draft (required), target.

How it works

prompt-forge does not call any LLM itself. When a tool is invoked it returns a self-contained instruction (expert guidance for the task + your draft); the host model (e.g. Claude in Claude Desktop) reads that and produces the result. So there is nothing to configure — it uses the model you already have.

Install

Add to your MCP host config (e.g. Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "prompt-forge": {
      "command": "npx",
      "args": ["-y", "github:Ayubjon/prompt-forge"]
    }
  }
}

No env block is needed. Restart the host, then ask it to use the enhance_prompt or critique_prompt tool.

Development

npm install
npm test          # unit tests (vitest)
npm run build     # compile to dist/
npm run smoke     # build + boot the server and list its tools
