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.
A matcher for a new session metadata endpoint exists but nothing calls it.
A URL recognizer for an MCP session-metadata path is present and unreferenced.

What
A new helper matches URLs on the session-ingress host used at startup whose path is exactly a new MCP metadata path. The host is captured once at startup into a holder that can be reset. Nothing in the build was found to call the recognizer, so what it gates is not visible from here.
Evidence

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