Promptimprover

Promptimprover is an MCP server middleware that intercepts and refines every AI prompt before code generation — applying project context, coding standards, and compounding memory. It runs as a local stdio server, intercepting every prompt sent by your AI coding assistant before it reaches the language model.

Quickstart

Add prompt-refiner to your MCP client configuration:

{
  "mcpServers": {
    "prompt-refiner": {
      "command": "prompt-refiner"
    }
  }
}
