MCP Router: protocols.stateless.statelessToLegacyBridge

statelessToLegacyBridge controls whether a stateless frontend request may be adapted to a session-oriented legacy MCP backend.

  • Type: String
  • Default and only supported value: reject

The current release deliberately fails closed: a stateless call to a tool whose backend profile is legacy returns an MCP tool error instead of creating or reusing hidden backend session state. Other values reject configuration. Use a tool with backendMcpProtocol: stateless and explicit credential settings for a stateless-to-stateless path.
