Released on August 8, 2026, mcp-filter-proxy v0.2.1 brings a key improvement to the way the proxy handles HTTP traffic, focusing on increasing the reliability and scalability of the service in modern deployment environments.

What’s new

The headline feature of this release is the introduction of Stateless HTTP Transport. When operating the proxy in HTTP mode using the --transport http flag, the server now runs in a stateless configuration.

This improvement is powered by an upgrade to the MCP Go SDK (v1.7.0), which enables the proxy to handle requests without requiring persistent session state.

Why it matters

For users deploying mcp-filter-proxy in cloud-native or containerized environments, this change is significant. By removing the need for session persistence, the proxy becomes far more robust and scalable.

Statelessness is particularly critical when the proxy is placed behind a load balancer or distributed across multiple instances. Requests can now be routed to any available proxy instance without the risk of session mismatch, ensuring a more stable and seamless connection between your local MCP client and remote services.

Getting Started

Upgrading to v0.2.1 is straightforward. You can download the latest binaries directly from the GitHub releases page or rebuild the project from source. The transition to stateless mode is transparent, meaning your existing configurations will continue to work while benefiting from the improved stability.
