Relays detailed error logs from other MCP servers to LLMs, enabling more intelligent error recovery and reducing token waste.
When LLM calls to MCP servers fail with vague or empty error messages, models often engage in wasteful blind retries, depleting token budgets without resolving the underlying issue. The MCP Error Relay addresses this by acting as a lightweight MCP server that provides LLMs with access to detailed server-side error logs. This crucial information allows LLMs to understand the root cause of failures, such as permission issues, and respond intelligently—whether by self-correcting, informing the user, or providing targeted solutions—instead of endlessly retrying broken calls.
