GenPark Tri-State Circuit Breaker Router

A local MCP server that routes LLM provider calls through a tri-state circuit breaker with sliding error windows and half-open probes.

What you can do

• Manage LLM provider failure cascades by routing requests through a tri-state circuit breaker.
• Track errors over sliding windows and run half-open probes to decide when a failing provider recovers.
• Run it as a local MCP server or import it as a Python library in agent workflows.
• No tool list is published, so the exact callable operations are not documented in the supplied material.

When to use it

Worth adding when an assistant or agent pipeline calls several LLM providers and you want failing ones skipped automatically instead of retried blindly. It suits setups that need resilience logic around provider outages rather than a general-purpose tool server.

Requirements

Runs as a local process over stdio, started with a Python script; the README states it uses only the Python standard library, so no third-party packages are needed. No authentication, environment variables or headers are declared. Desktop-only; not executable on the web.
