Matrix Administration

Quality score: 70/100 · Category: Security · Sub-category: forensics

type:audit

Use when administering a Synapse / Matrix homeserver — list or snapshot all rooms, rate room health (public, unencrypted, orphaned), render a Graphviz map of the room/space tree, force-join users, promote room admins, harden rooms (add-to-space + restrict + encrypt), deactivate Matrix users (with GDPR erase), find biggest rooms by DB size, audit where a user is admin or member, replay join/leave timelines, or search unencrypted history. Trigger on any '/_synapse/admin', server-wide room operation, Matrix user offboarding, or anything requiring a homeserver-admin token — even without 'admin API' in the prompt. Companion to matrix-communication.
