Dr Strange runs on your own machine — the client starts it, so there is no endpoint to ping. 966 installs a week from npm. Last commit 8 Nov 2026.
Code graph for coding agents: who calls this, what a change reaches, in one round trip.
Today is the operative word: we check Dr Strange every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

<DRSG_TOKEN> (Bearer token this server requires of every client, and the value the Authorization header above is built from. Any secret will do — it is checked against itself, not issued by anything).
