# Aurora MySQL MCP Server

> Connect Amazon Aurora MySQL to Claude, Cursor, ChatGPT, Codex, and Windsurf with QueryBear — a secure, read-only MCP server.

[Amazon Aurora](https://aws.amazon.com/rds/aurora/) MySQL-Compatible Edition is AWS's high-performance managed MySQL. QueryBear connects over the standard MySQL protocol, giving your AI clients safe, read-only access through QueryBear's [security gateway](/features/security).

> Using Aurora PostgreSQL-Compatible Edition? See [AWS Aurora (Postgres)](/integrations/aws-aurora).

## Get your Aurora MySQL connection details

Aurora clusters expose two endpoints:

* **Writer (cluster) endpoint** — the primary instance.
* **Reader endpoint** — load-balances across replicas. **Use this for QueryBear.**

Find both in the [RDS console](https://console.aws.amazon.com/rds/) under your Aurora cluster's **Connectivity & security** tab. The MySQL port is `3306`.

## Allow QueryBear's IP

1. Get QueryBear's egress IP from the dashboard under **Connections → Network**.
2. Add an inbound rule to the cluster's **security group** for that IP on port `3306`.
3. Ensure the cluster is publicly accessible or reachable via VPC peering / PrivateLink.

## Create a read-only user

Use the [MySQL read-only user SQL](/databases/mysql#create-a-read-only-mysql-user). Run it against the writer endpoint, then connect QueryBear to the reader endpoint.

## Add the connection to QueryBear

In the [QueryBear dashboard](https://querybear.com/dashboard) → **Connections** → **New connection** → **MySQL**. Use the **reader endpoint**, port `3306`, your `querybear` user, and **SSL mode `require`**.

## Aurora MySQL-specific notes

* **Reader endpoint for reads:** Keeps AI query load off the writer.
* **TLS:** Aurora supports the Amazon RDS CA bundle; QueryBear connects over TLS.
* **Multi-statement queries blocked** at the parser.
