It:\n\n- Transforms `\/ws\/` paths to `\/session\/` and appends `\/events`\n- Includes retry logic with multiple attempts\n- Handles client errors (4xx except 429) by not retrying\n- Uses session tokens for authentication\n- Falls back gracefully if no session token is available\n\nThis supplements the existing WebSocket transport with an HTTP POST channel, likely improving reliability of the Claude in Chrome MCP bridge connection. The bridge URL is logged at startup, showing \"none (using native socket)\" when no bridge is configured.\n\n**Evidence**\n\nHybridTransport implementation (search for `\"HybridTransport: POST URL =\"`)"}
