Interactive Feedback MCP

Why Use This?

By guiding the AI assistant to check in with the user instead of branching out into speculative, high-cost tool calls, this module can drastically reduce the number of premium requests. In some cases, it helps consolidate what would be up to 25 tool calls into a single, feedback-aware request — saving resources and improving performance.

Quick Install (Recommended)

One command to clone, install, and configure everything automatically for Antigravity IDE:

Windows (PowerShell):

irm https://raw.githubusercontent.com/nhatpse/Antigravity-MCP/v1.3.3/install.ps1 | iex

Linux / macOS:

curl -fsSL https://raw.githubusercontent.com/nhatpse/Antigravity-MCP/v1.3.3/install.sh | bash

The installer will: clone the repo → install dependencies → configure MCP server → add coding rules. Just restart Antigravity after it finishes.

Manual Installation

Prerequisites

• uv (Python package manager). Note: You do not need Python installed on your machine; uv will download and manage the required Python version automatically!
  • Windows: irm https://astral.sh/uv/install.ps1 | iex
  • Linux/Mac: curl -LsSf https://astral.sh/uv/install.sh | sh

Setup

1. Clone or download this repository.

2. Install dependencies:

   cd path/to/interactive-feedback-mcp
   uv sync

3. Add the MCP server to your Antigravity configuration (~/.gemini/antigravity/mcp.json):

   {
     "mcpServers": {
       "interactive-feedback-mcp": {
         "command": "uv",
         "args": [
           "--directory",
           "/path/to/interactive-feedback-mcp",
           "run",
           "server.py"
         ]
       }
     }
   }

   Note: If uv is not in your system PATH, use the full path to the uv executable instead (e.g., C:\\Users\\<user>\\AppData\\Local\\Python\\...\\Scripts\\uv.exe).

Prompt Engineering

For the best results, add the following as a coding rule in your AI assistant:

Whenever you want to ask a question, always call the MCP interactive_feedback.
Whenever you're about to complete a user request, call the MCP interactive_feedback instead of simply ending the process. Keep calling MCP until the user's feedback is empty, then end the request.

Adding Rules in Antigravity

1. Click Antigravity - Settings at the bottom of the chat panel.
2. In the Agent settings, click Manage next to Customizations.
3. Click + Global to add a global coding rule, then paste the prompt above.

Development

To run the server in development mode with a web interface for testing:

uv run fastmcp dev server.py
