Normally the MCP library would send a GET request to the proxy to open a notification stream, a long-lived connection over which the server can push updates.\n\nFor claude.ai proxy connectors, Claude Code now answers that GET request itself with a 405, the standard \"method not allowed\" reply, so the request is never sent and the stream is never opened. Before, this only happened for stateless connectors, meaning connectors that do not keep state between requests. The behaviour is controlled by the `tengu_serene_teapot` gate, a switch the server can turn on or off per account.\n\n**Why**\n\nWith the stream not opened, claude.ai connectors cannot push notifications to Claude Code. Their tools are still called through normal requests.\n\n- Flag `tengu_serene_teapot`: Not enough to say (read for one account on one subscription tier against v2.1.281; this account: no value returned, anonymous baseline: no value returned, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: MCP\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 2\/5"}
