AI Intervention Agent

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"]
    }
  }
}

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 (loopback URLs auto-suppressed; LAN-IP suggestion surfaced in settings)

• SSH / LAN friendly: works behind port forwarding; mDNS publishes a <host>.local URL when the local network supports it

• Server self-info resource (aiia://server/info): live runtime / fastmcp version / middleware chain / task-queue snapshot for cross-tool diagnostics

• MCP-spec compliant (2025-11-25 protocol): tool annotations, server identity, and self-contained icons let ChatGPT Desktop / Claude Desktop / Cursor render the server natively without nagging "destructive operation" confirmations

• Production-grade middleware: ErrorHandling + RateLimiting (10 req/s, burst 20) + Timing + Logging chain, with structured task.created / task.completed events forwarded to the MCP client via ctx.info

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 the task using a dual-channel transport: SSE (GET /api/events, with Last-Event-ID resume) for real-time updates, and HTTP polling as a safety net when SSE drops.

4. When you submit feedback, the Web UI completes the task in the task queue.

5. The MCP server waits via SSE + a low-frequency HTTP poll (GET /api/tasks/{task_id}), then 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. Bark URLs that resolve to loopback addresses are automatically suppressed and the Web UI surfaces a LAN-IP suggestion in the settings panel.

VS Code extension (optional)

The diagram intentionally shows top-level processes and the most visible modules. Internal helpers — e.g. state_machine.py (per-task lifecycle), web_ui_mdns.py (LAN service discovery via mDNS), web_ui_security.py (CSRF / origin / token gates), task_queue_singleton.py (single-process queue access), server_feedback.py (the interactive_feedback MCP tool body), enhanced_logging.py, protocol.py, etc. — live in the same two processes and are documented per-module under docs/api/ (English) and docs/api.zh-CN/ (中文).
