AiBridge Extension

A VS Code extension that exposes an HTTP API on 127.0.0.1:9999 allowing external applications to inject text into the editor's AI chat. Works with VS Code, Cursor, and other VS Code-based editors.

Supported Editors

• VS Code — injects into Copilot Chat (workbench.action.chat.open + workbench.action.chat.submit)
• Cursor — injects into Composer (composer.focusComposer + OS-level Enter)
• Windsurf — injects via clipboard paste into agent panel (antigravity.openAgent + antigravity.toggleChatFocus + OS-level Enter)
• Other VS Code forks — falls back to VS Code behavior; detected at runtime via available commands

Installation

1. Build the extension: npm install && npm run compile
2. Package: npm run package
3. Install the .vsix file in your editor (VS Code, Cursor, etc.)

HTTP API

GET /health

Health check endpoint.

curl http://127.0.0.1:9999/health

Response:

{"status": "ok", "version": "1.1.0", "editor": "cursor"}

The editor field is detected at runtime ("vscode", "cursor", or "windsurf").

GET /status

Get server status.

curl http://127.0.0.1:9999/status

Response:

{"child_tool": "cursor", "idle": true, "queueLength": 0, "chatOpen": true}

POST /inject

Queue text for injection into the editor's AI chat.

curl -X POST http://127.0.0.1:9999/inject \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello from external app"}'

Options:

• ?sync=true - Wait for injection to complete before responding
• priority field - Higher priority items are processed first

Response:

{"queued": true, "queueLength": 1}

DELETE /queue

Clear pending injections.

curl -X DELETE http://127.0.0.1:9999/queue

Permissions

Auto-submit requires different mechanisms depending on the editor:

• VS Code: Uses native workbench.action.chat.submit command — no extra permissions needed
• Windsurf: Uses clipboard paste for injection and OS-level Enter for submit:
  • macOS: System Settings → Privacy & Security → Accessibility → Enable for Windsurf
  • Windows: No additional permissions required
  • Linux: Requires xdotool installed (sudo apt install xdotool)
• Cursor: Uses OS-level keyboard simulation:
  • macOS: System Settings → Privacy & Security → Accessibility → Enable for Cursor
  • Windows: No additional permissions required
  • Linux: Requires xdotool installed (sudo apt install xdotool)

Set aibridge.paranoid: true to disable auto-submit and avoid permission prompts.

Configuration

Commands

• AiBridge: Start Server - Start the HTTP server
• AiBridge: Stop Server - Stop the HTTP server
• AiBridge: Show Status - Show server status

Used By

MobAI — a desktop app that gives AI coding agents the ability to see and control mobile devices. MobAI uses the AiBridge Extension to inject mobile app context (screenshots, UI trees, device state) directly into VS Code, Cursor, and Windsurf AI chats.
