MCP Router: maxSessions

maxSessions caps legacy frontend sessions stored by one gateway process.

  • Type: Positive integer
  • Default: 10000

Before rejecting a new initialize request, the router purges expired sessions. Legacy sessions expire after 30 minutes of inactivity and the normal purge interval is one minute. If the store remains full, initialization returns HTTP 503 with an MCP resource-limit error. Stateless requests do not consume this session store. Each gateway replica enforces its own limit.
