MCP Router: protocols.stateless.maxConcurrentRequests

maxConcurrentRequests caps in-flight stateless MCP requests in one gateway process.

  • Type: Positive integer
  • Default: 1024

Admission is fail-fast and uses an owned semaphore, so completion, cancellation, or panic releases capacity automatically. When no global permit is available, the request returns HTTP 429 with an MCP resource-limit error. Legacy session requests use separate controls.
