List binary log files and positions.
AI agents call mysql_binary_logs to retrieve information from Mysql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about binary logs (file names and positions) without creating, modifying, or deleting any data. It is informational in nature, supporting monitoring and diagnostic purposes. No side effects occur. This is a clear Read category operation with low severity since exposure would only allow an agent to view existing log metadata.
From the tool's definition Tool description states 'List binary log files and positions' — a purely query operation with no modification capability. The server is explicitly described as 'read-only queries' focused on 'performance analysis, and server monitoring.'
Documented attack patterns abuse exactly the kind of access mysql_binary_logs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mysql, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_binary_logs:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_binary_logs": {}
}
}mysql_binary_logs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List binary log files and positions. It is categorised as a Read tool in the Mysql MCP Server, which means it retrieves data without modifying state.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_binary_logs: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mysql. Nothing to install.
mysql_binary_logs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mysql_binary_logs rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mysql_binary_logs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mysql_binary_logs is provided by the Mysql MCP server (mukul975/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mysql, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
