AI Intervention Agent

AI Intervention Agent

Real-time user intervention for MCP agents.

English | 简体中文

When using AI CLIs/IDEs, agents can drift from your intent. This project gives you a simple way to intervene at key moments, review context in a Web UI, and send your latest instructions via interactive_feedback so the agent can continue on track.

Works with Cursor, VS Code, Claude Code, Augment, Windsurf, Trae, and more.

Quick start

Option 1: Using uvx (Recommended)

Configure your AI tool to launch the MCP server directly via uvx (this automatically installs and runs the latest version):

{
  "mcpServers": {
    "ai-intervention-agent": {
      "command": "uvx",
      "args": ["ai-intervention-agent"],
      "timeout": 600,
      "autoApprove": ["interactive_feedback"]
    }
  }
}

Option 2: Using pip

1. First, install the package manually (please remember to manually pip install --upgrade ai-intervention-agent periodically to get updates):

pip install ai-intervention-agent

2. Configure your AI tool to launch the installed MCP server:

{
  "mcpServers": {
    "ai-intervention-agent": {
      "command": "ai-intervention-agent",
      "args": [],
      "timeout": 600,
      "autoApprove": ["interactive_feedback"]
    }
  }
}

[!NOTE] interactive_feedback is a long-running tool. Some clients have a hard request timeout, so the Web UI provides a countdown + auto re-submit option to keep sessions alive.

• Default: feedback.frontend_countdown=240 seconds
• Max: 250 seconds (to stay under common 300s hard timeouts)

3. (Optional) Customize your config:

• On first run, config.toml will be created under your OS user config directory (see docs/configuration.md).
• Example:

[web_ui]
port = 8080

[feedback]
frontend_countdown = 240
backend_max_wait = 600

- Only ask me through the MCP `ai-intervention-agent` tool; do not ask directly in chat or ask for end-of-task confirmation in chat.
- If a tool call fails, keep asking again through `ai-intervention-agent` instead of making assumptions, until the tool call succeeds.

ai-intervention-agent usage details:

- If requirements are unclear, use `ai-intervention-agent` to ask for clarification with predefined options.
- If there are multiple approaches, use `ai-intervention-agent` to ask instead of deciding unilaterally.
- If a plan/strategy needs to change, use `ai-intervention-agent` to ask instead of deciding unilaterally.
- Before finishing a request, always ask for feedback via `ai-intervention-agent`.
- Do not end the conversation/request unless the user explicitly allows it via `ai-intervention-agent`.

Key features

• Real-time intervention: the agent pauses and waits for your input via interactive_feedback
• Web UI: Markdown, code highlighting, and math rendering
• Multi-task: tab switching with independent countdown timers
• Auto re-submit: keep sessions alive by auto-submitting at timeout
• Notifications: web / sound / system / Bark
• SSH-friendly: great with port forwarding

How it works

1. Your AI client calls the MCP tool interactive_feedback.
2. The MCP server ensures the Web UI process is running, then creates a task via HTTP (POST /api/tasks).
3. The browser (or VS Code Webview) renders tasks by polling the Web UI API.
4. When you submit feedback, the Web UI completes the task in the task queue.
5. The MCP server polls for completion (GET /api/tasks/{task_id}) and returns your feedback (text + images) back to the AI client.
6. Optionally, the MCP server triggers notifications (Bark / system / sound / web hints) based on your config.

VS Code extension (optional)
