What Minibridge does

Minibridge serves as a backend-to-frontend bridge, streamlining and securing communication between Agents and MCP servers. It safely exposes MCP servers to the internet and can optionally integrate with generic policing services — known as Policers — for agent authentication, content analysis, and transformation. Policers can be implemented remotely via HTTP or locally using OPA Rego policies.

Minibridge

Minibridge can help ensure the integrity of MCP servers through SBOM (Software Bill of Materials) generation and real-time validation.

Additionally, Minibridge supports OTEL and can report/rettach spans from classical OTEL headers, as well as directly from the MCP call, as inserted by certain tool like Open Inference.

Minibridge Frontend: The Client connects to the Frontend part of Minibridge.
Minibridge Backend: The Frontend connects to the Backend which wraps the MCP server.
Minibridge Policer: The Policer runs in the Backend and can optionally take decision on the input and output based on some policies (locally with Rego or remotely using HTTPs)

[!TIP] Conveniently, Minibridge can be started in an "all-in-one" (AIO) mode to act as a single process.

Why using Minibridge ?

Minibridge covers the following:

Secure Transport: Use TLS with optionally, client certificate validation
Integrity: Ensure the MCP server can not mutate tools, templates, etc. during the execution
User Authentication: Transport the user information to the Policer
Monitoring: Expose prometheus metrics
Telemetry: Report traces and spans using Opentelemetry

Installation

Minibridge can be installed from various places:

Homebrew

On macOS, you can use Homebrew
