How to prevent your server’s rooms from being indexed
Important context ⚠️
Rooms indexed by MatrixRooms.info were made visible because the server administrator explicitly configured them to be public and federated. Indexing is a direct consequence of a series of intentional decisions on your side — not an action performed arbitrarily by MatrixRooms.info.
To be indexed, a room must meet all of the following conditions:
- Marked as federatable during creation
- Set as public in room settings
- Published in the server’s room directory
- Server must publish its room directory over federation
Every step involves an explicit choice. If a room is indexed, it’s because these permissions were deliberately granted. MatrixRooms.info simply reflects publicly available information; it does not bypass or override any Matrix server settings.
How to stop publishing your rooms 🌐
If you want to prevent indexing in the future, the correct solution is to stop publishing your server’s room directory over federation.
For Synapse servers, modify your homeserver.yaml:
allow_public_rooms_over_federation: falseFor etke.cc/ansible or MDAD setups, add this to your vars.yml:
matrix_synapse_allow_public_rooms_over_federation: falseThis change will prevent your server from advertising public rooms over federation, and therefore they won't appear in any external indexes like MatrixRooms.info.
Block specific rooms only 🏷️
If you prefer to block only certain rooms without changing server-wide settings, you can add the following exact string to the room’s topic or description:
matrixrooms.info:noindex
MatrixRooms.info will respect this tag and exclude the room from indexing.
