Requirements

• Python 3.11+
• uv (Python package manager)
• Flutter 3.x+ (for frontend development/building)

Installation

Option A: Install from PyPI (recommended for users)

pip install leo-feedback-mcp

Or with uv:

uv pip install leo-feedback-mcp

MCP configuration (.cursor/mcp.json):

{
  "mcpServers": {
    "leo-feedback-mcp": {
      "command": "uvx",
      "args": ["leo-feedback-mcp"],
      "timeout": 600,
      "autoApprove": ["interactive_feedback"]
    }
  }
}

Option B: Install from source (for development)

git clone <your-repo-url> ~/Desktop/leo-feedback-mcp
cd ~/Desktop/leo-feedback-mcp
make init
make build

MCP configuration (.cursor/mcp.json):

{
  "mcpServers": {
    "leo-feedback-mcp": {
      "command": "uv",
      "args": ["run", "--directory", "<path-to-leo-feedback-mcp>", "leo-feedback-mcp"],
      "timeout": 600,
      "autoApprove": ["interactive_feedback"]
    }
  }
}

Replace <path-to-leo-feedback-mcp> with the actual path to the cloned repository.

Apply configuration

You can place the MCP config in:

• Project-level: .cursor/mcp.json in your project root
• Global: ~/.cursor/mcp.json to apply across all projects

After editing, restart Cursor or reload MCP servers (Cursor Settings > MCP > Reload).

Usage

Once configured, the AI assistant will automatically call interactive_feedback to collect your feedback during conversations. A Web UI will open in your browser where you can:

1. Review the AI's work summary (Markdown rendered)
2. Provide text feedback with keyboard shortcuts
3. Attach images via upload button, drag & drop, or paste
4. View session history of previous AI interactions
5. Configure auto-submit prompts and timeout settings

Environment Variables

Variable	Description	Default
MCP_DEBUG	Enable debug logging	false
MCP_WEB_HOST	Web UI host	127.0.0.1
MCP_WEB_PORT	Web UI port	8765
