On July 17, 2026, we are excited to announce the official launch of mcp-filter-proxy v0.1.0. This project introduces a powerful, controlled proxy for the Model Context Protocol (MCP), designed to sit between your MCP clients and remote servers to enhance security, compatibility, and management.

For many users, the gap between stdio-only clients and remote streamable-HTTP servers has been a hurdle. mcp-filter-proxy solves this by acting as a secure bridge, ensuring that your local environment can interact with remote services without compromising on control or security.

Project Highlights

As this is our first release, mcp-filter-proxy arrives with a robust set of core capabilities:

Seamless Transport Bridging

The proxy allows stdio-based MCP clients to communicate effortlessly with remote MCP servers over streamable HTTP. Additionally, you can run the proxy in HTTP mode to expose the remote server’s capabilities via a local HTTP endpoint, making it easier to share MCP services across your local network.

Precise Tool Filtering

Control exactly what your clients can do. With our pattern-based filtering system, you can use include and exclude wildcards to restrict which tools are visible and callable. This ensures that clients only have access to the specific functionality they need, reducing the attack surface of your remote servers.

Enterprise-Ready Authentication

Manage your secrets in one place. Instead of configuring tokens across multiple clients, mcp-filter-proxy centralizes authentication:

  • Static Tokens: Support for custom headers and prefixes.
  • OAuth 2.0 Client Credentials: Full automation of the client credentials flow, including proactive in-memory token refreshing and exponential backoff for reliability.

Custom Header Injection

Need to pass specific tenant IDs or custom metadata to your remote server? The proxy allows you to inject arbitrary outbound HTTP headers into every request, providing the flexibility needed for complex enterprise environments.

Why It Matters

In an ecosystem where MCP servers are becoming increasingly distributed, the ability to govern access is critical. mcp-filter-proxy provides a “security gate” that prevents over-privileged client access and simplifies the deployment of remote MCP services. By decoupling authentication and tool visibility from the client, administrators gain a centralized point of control, making the entire system more maintainable and secure.

Getting Started

mcp-filter-proxy is available now! You can get started in a few ways:

  • Binary Downloads: Grab a pre-built binary for Linux, macOS, or Windows from our GitHub releases page.
  • Go Install: If you have Go installed, you can quickly install the latest version using: 
    go install github.com/UnitVectorY-Labs/mcp-filter-proxy@latest

We are thrilled to bring this tool to the community and look forward to seeing how it helps you scale your MCP deployments.
