Bridge

Bridge MCP is an MCP server that enables any AI to control a Windows PC through a secure, extensible interface. It provides tools for automating applications, input, screen capture, system commands, and web browser interactions, all orchestrated via a standardized MCP protocol so you can empower AI assistants to perform complex tasks on your machine.

How to use

You will run the MCP server locally or on FastMCP Cloud and connect your AI client to it. The server exposes a set of capabilities that let the AI launch and manage applications, simulate input, capture the screen, automate browser actions, run system commands, and manage the clipboard. You interact with the server through an agent that registers with your AI client and persists across sessions.

How to install

{ 
  "type": "stdio",
  "name": "bridge_mcp_local",
  "command": "python",
  "args": ["C:\\Users\\YourName\\Path\\To\\Bridge-MCP\\bridge_mcp.py"]
}

Prerequisites: you need Python installed on your system. You may also want to install additional runtime dependencies referenced by the project, such as a package manager and a web browser automation library.

Step 1: Clone the project

• 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 may auto-install on first use.

Step 3: Start the local MCP server

• python bridge_mcp.py

Step 4: Start the local agent (Windows)

• python local_agent.py

Step 5: Register your agent in your AI client using the provided agent callback URL (for example http://127.0.0.1:8006) and agent name.

Additional setup options

If you want to access your MCP server remotely, you can deploy it to FastMCP Cloud. You will receive a URL like the following where your MCP will be reachable: https://your-project.fastmcp.app/mcp. Use this URL in your client configuration to route requests to the cloud-hosted MCP.

Configuration through clients like Claude Desktop, Cursor, or VS Code can point to the local or cloud MCP endpoint. The standard approach is to configure the client to call the bridge_mcp server using the registered agent callback URL and the appropriate agent identifier.

Security considerations include token-based auth and a safety mode that requires explicit approval for dangerous actions. Ensure your local agent and MCP server are protected behind a firewall and are not exposed publicly without proper authentication.

Troubleshooting and notes

If you encounter issues, verify that the local MCP server and agent are running in their respective terminals. Check that the configured paths point to the actual bridge_mcp.py and local_agent.py files. If your client reports no agents or server disconnection, confirm registration status and reachability of the callback URL.

For cloud deployments, ensure the project has been built and deployed correctly, and that the cloud URL is used as the callback in your AI client. If you need to restart services, stop and start the local server and agent in sequence.

Notes on security and observability

Bridge MCP includes a Safety Sentinel that requires you to approve sensitive commands and provides an approval overlay in the AI activity view. You can monitor pending requests from the web dashboard and toggle Safe Mode as needed.

Live observability features include a dashboard with a high-fidelity desktop stream and visual overlays that indicate what the AI detects on the screen. This helps you verify that the AI interactions target the correct UI elements.

Semantic capabilities and resources

The server exposes resources for desktop state, screenshots, and file access, and supports prompts and session memory so your AI can maintain context across interactions.

Compliance and extension points

Bridge MCP implements a complete MCP specification, enabling rich workflows from task automation to web automation templates. You can extend it with additional tools and integrate new automation scenarios as needed.

Examples of use

Example: you can have the AI open a text editor, type content, and save the file, or you can automate browser actions to perform web searches and extract results.

What you get with Bridge MCP

A scalable, secure bridge between any MCP-compliant AI and your Windows PC, enabling automated control of applications, input, screen capture, and browser automation.
