TiDB is a distributed SQL database that’s wire-compatible with MySQL. QueryBear connects over the MySQL protocol, giving your AI clients safe, read-only access through QueryBear’s security gateway.

​
Get your TiDB connection details

  1. Open the TiDB Cloud console.
  2. Select your cluster → Connect.
  3. Copy the host, port (4000), database, username, and password. TiDB Cloud Serverless usernames are prefixed (e.g. xxxxx.root).

​
Create a read-only user

TiDB supports MySQL-compatible user management. Use the MySQL read-only user SQL: 
CREATE USER 'querybear'@'%' IDENTIFIED BY 'choose-a-strong-one';
GRANT SELECT ON your_db.* TO 'querybear'@'%';
GRANT SHOW VIEW ON your_db.* TO 'querybear'@'%';
FLUSH PRIVILEGES;

​
Add the connection to QueryBear

In the QueryBear dashboard → Connections → New connection → MySQL. Enter the TiDB host, port 4000, database, username (with prefix if Serverless), and SSL mode require — TiDB Cloud requires TLS.

​
TiDB-specific notes

  • Port 4000, not the MySQL default 3306.
  • TLS required on TiDB Cloud Serverless. Use require.
  • Username prefix: Serverless clusters use a prefixed username — copy it exactly from the console.
  • Distributed, MySQL-compatible: SELECT queries behave like MySQL. QueryBear’s schema introspection handles TiDB’s catalog.
