DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

HybridTransport for MCP Bridge

A new HybridTransport class has been added that converts WebSocket URLs to HTTP POST endpoints for sending events. It:

  • Transforms /ws/ paths to /session/ and appends /events
  • Includes retry logic with multiple attempts
  • Handles client errors (4xx except 429) by not retrying
  • Uses session tokens for authentication
  • Falls back gracefully if no session token is available

This 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.

Evidence

HybridTransport implementation (search for "HybridTransport: POST URL =")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
