Minibridge MCP Server

What is Minibridge?

Minibridge is a backend-to-frontend bridge that streamlines and secures communication between AI Agents and MCP servers. It safely exposes MCP servers to the internet and can optionally integrate with policing services (Policers) for agent authentication, content analysis, and transformation.

How to use Minibridge?

Install Minibridge via Homebrew, AUR, Go toolchain, or download a binary from the release page. In your MCP client configuration, replace the original server command with minibridge aio -- <original command> to wrap the server in all-in-one mode, enabling SBOM checks and policy enforcement.
