Show auto-increment information for tables.
AI agents call mysql_auto_increment_info 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 queries and retrieves auto-increment metadata about tables without modifying any data or schema. It falls squarely into the Read category as it has no side effects beyond information retrieval. Severity is low because exposing this metadata poses minimal direct risk—it reveals implementation details but does not enable data manipulation or destruction.
From the tool's definition Tool name 'mysql_auto_increment_info' and description 'Show auto-increment information for tables' indicate a retrieval operation with no modification. The verb 'show' and context of querying metadata are consistent with read-only operations.
Documented attack patterns abuse exactly the kind of access mysql_auto_increment_info 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_auto_increment_info:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_auto_increment_info": {}
}
}mysql_auto_increment_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show auto-increment information for tables. 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_auto_increment_info: 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_auto_increment_info 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_auto_increment_info 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_auto_increment_info. 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_auto_increment_info 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.
