Minibridge MCP Server

What is Minibridge?

Minibridge is a backend-to-frontend bridge that streamlines and secures communication between Agents and MCP servers. It safely exposes MCP servers to the internet and can integrate with policers for agent authentication, content analysis, and transformation. It also supports SBOM generation and validation to ensure MCP server integrity.

How to use Minibridge?

Minibridge can be used as a single all‑in‑one gateway (minibridge aio), a backend that exposes MCP servers over WebSockets (minibridge backend), a frontend that translates stdio/HTTP+SSE to WebSockets (minibridge frontend), or a scanning tool (minibridge scan). For example, start an all‑in‑one gateway with minibridge aio --listen :8000 -- npx @modelcontextprotocol/server-filesystem /tmp.

Key features of Minibridge

• Acts as a bridge between agents and MCP servers.
• Supports multiple frontend transports: stdio, HTTP+SSE, and WebSocket.
• Integrates with Policers (HTTP or Rego) for authentication and analysis.
• Generates and validates SBOMs for MCP server integrity.
• Supports TLS and mutual TLS for secure connections.
• Enables live SBOM validation of MCP calls.

Use cases of Minibridge

• Exposing a local MCP server securely to agents over the internet.
• Authenticating and monitoring agent requests via a custom HTTP or Rego policer.
• Ensuring an MCP server has not been tampered with using offline or online SBOM checks.
• Connecting legacy HTTP+SSE agents to a WebSocket‑based MCP backend.
