๐Ÿ”„ How Persistence Works

Bridge MCP v2.0 stores agent registrations in a persistent JSON file:

  • Windows: %APPDATA%\bridge-mcp\agents.json
  • Linux/Mac: ~/.config/bridge-mcp/agents.json

This means:

  • โœ… Register once, works forever
  • โœ… Survives Claude Code session restarts
  • โœ… Survives computer reboots
  • โœ… Works across all AI clients

First-Time Setup

  1. Start the local agent:
   cd Bridge-MCP
   python local_agent.py
  1. The agent auto-registers itself - no manual registration needed!

  2. Verify in any Claude session:

   Use list_agents() to see registered agents

Troubleshooting

If you see "No agents connected":

  1. Check if local_agent.py is running - it must be running in a terminal
  2. Check health: Use check_agent_health() tool
  3. Manual register: Use register_agent("local", "http://127.0.0.1:8006", "My PC")

Running Local Agent as Background Service

For always-on access, install local_agent as a Windows service:

python install_service.py install
python install_service.py start

To remove:

python install_service.py stop
python install_service.py remove

  • bridge_mcp.py - MCP server (runs locally or on FastMCP Cloud)
  • local_agent.py - HTTP server on your PC that executes commands (port 8006)

๐Ÿ”’ Enterprise-Grade Security

Bridge MCP 2.0 includes:

  • Auth Tokens: Uses secure Bearer tokens to prevent unauthorized access.
  • Auto-Config: Tokens are auto-generated and saved to agents.json.

๐ŸŒ Next-Gen Browser Automation

Powered by Playwright, Bridge MCP can now:

  • Click & Type: Interact with any website element.
  • Semantic Understanding: Read page content programmatically.
  • Headless Mode: Run automations invisible or visible.

๐Ÿง  Semantic Computer Vision

Bridge MCP "sees" your apps:

  • UI Tree: It can read the accessibility tree of Windows apps.
  • Precision: Knows exactly where buttons are (no more guessing pixels).

๐Ÿ›ก๏ธ Safety Sentinel (Human-in-the-Loop)

Bridge MCP now puts YOU in control:

  • Command Interception: Dangerous commands (writing files, running shell scripts) are BLOCKED by default.
  • Approval Overlay: Approval requests appear directly in the AI Activity Overlay with three options:
    • โœ“ APPROVE - Execute this one command
    • โœ— DENY - Block this command
    • โœ“ ALWAYS APPROVE - Disable Safe Mode and approve all future commands
  • Dashboard Control: View all pending requests at http://localhost:8006
  • Safe Mode Toggle: Switch Safe Mode on/off anytime from the web dashboard
  • Peace of Mind: You can leave the agent running without fear of it deleting your files.

๐Ÿ‘๏ธ Terminator Vision (Live Observability)

See what the AI sees, in real-time:

  • Live Stream: The dashboard features a low-latency 1080p MJPEG stream of your desktop.
  • Semantic Overlay: Green bounding boxes highlight every button, link, and window the AI detects.
  • Debug Instantly: Visual confirmation that the AI has found the correct "Submit" button.

๐Ÿ“š Full MCP Specification Support

Bridge MCP now implements the complete Model Context Protocol specification:

Resources API

Expose desktop data as addressable resources:

  • desktop://screenshot/latest - Current screenshot
  • desktop://windows - Open windows list
  • desktop://logs - Agent command logs
  • file:///{path} - Read any desktop file
  • desktop://session/context - Recent session history

Prompts API

Pre-built workflow templates for one-click automation:

  • automate_desktop_task - Step-by-step task automation
  • debug_error - Interactive error debugging
  • web_automation - Playwright web workflows

Session Memory

Never lose context:

  • Stores last 100 commands across restarts
  • Provides AI with recent session history
  • Enables "continue where I left off" workflows

๐Ÿš€ Quick Start

Step 1: Clone the Repository

git clone https://github.com/BarhamAgha1/Bridge-MCP.git
cd Bridge-MCP

Step 2: Install Dependencies

pip install -r requirements-local.txt

Note: Playwright browsers (~100MB) auto-install on first use - no manual setup needed!

Step 3: Start the Local Agent

python local_agent.py

Keep this terminal open! The agent will display:

Bridge MCP Local Agent running on http://127.0.0.1:8006

Step 4: Configure Your AI Client

See Configuration below for Claude Desktop, Cursor, or VS Code setup.

Step 5: Register Your Agent

In your AI conversation, register the local agent:

Use register_agent with:
- agent_id: "my-pc"
- callback_url: "http://127.0.0.1:8006"
- agent_name: "My Windows PC"

Step 6: Start Controlling!

Now use any tool like screenshot(), click(100, 200), type_text("Hello"), app_launch("notepad"), etc.


๐Ÿ”ง Configuration

Claude Desktop

  1. Open the config file at %APPDATA%\Claude\claude_desktop_config.json

  2. Add Bridge MCP:

{
  "mcpServers": {
    "bridge-mcp": {
      "command": "python",
      "args": ["C:\\Users\\YourName\\Path\\To\\Bridge-MCP\\bridge_mcp.py"]
    }
  }
}

โš ๏ธ Important: Replace the path with the actual location where you cloned the repository!

Example paths:

  • C:\\Users\\PC\\Desktop\\Bridge-MCP\\bridge_mcp.py
  • D:\\Projects\\Bridge-MCP\\bridge_mcp.py
  1. Restart Claude Desktop completely (close and reopen)

Cursor

Add to your MCP settings in Cursor preferences with the same configuration format.

VS Code + Claude Code

Create .vscode/mcp.json in your project:

{
  "mcpServers": {
    "bridge-mcp": {
      "command": "python",
      "args": ["C:\\Users\\YourName\\Path\\To\\Bridge-MCP\\bridge_mcp.py"]
    }
  }
}

Remote Access (Optional)

To control your PC from anywhere, expose the local agent with ngrok:

ngrok http 8006

Then use the ngrok URL (e.g., https://xxxx.ngrok.io) as your callback_url when registering.

AI uses:
1. screenshot()
2. [AI analyzes the image and describes what it sees]

Example 3: Search on Google

User: Search for "Bridge MCP" on Google

AI uses:
1. chrome_open("https://google.com")
2. type_text("Bridge MCP")
3. press_key("enter")

๐Ÿ”ง Troubleshooting

Claude Desktop shows "Server disconnected"

  1. Check the path - Make sure the path in your config points to the actual bridge_mcp.py file. The path must be absolute and use double backslashes (\\) in JSON.

  2. Test manually - Open Command Prompt and run:

   cd "C:\path\to\Bridge-MCP"
   python bridge_mcp.py

It should stay running (not exit immediately). Press Ctrl+C to stop.

  1. Install dependencies:
   pip install fastmcp httpx
  1. Restart Claude Desktop - Fully close and reopen after any config changes.

Local agent not receiving commands

  1. Make sure local_agent.py is running in a terminal (keep it open!)
  2. Verify the callback URL is correct when registering the agent
  3. For local use: http://127.0.0.1:8006
  4. For remote access: Use ngrok (ngrok http 8006) and use the ngrok URL

"No agents connected" error

You need to register your local agent first:

register_agent("my-pc", "http://127.0.0.1:8006", "My PC")

Unicode/Emoji errors on Windows

If local_agent.py crashes with Unicode errors, the terminal may not support emojis. This has been fixed in the latest version.
