Get the credentials for a SkySQL database instance
AI agents call get_db_credentials to retrieve information from Skysql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves (does not modify or execute) database credentials, placing it in the Read category. However, severity is elevated to medium rather than low because exposure of credentials could enable unauthorized database access, even though the tool itself performs no destructive action. Confidence is high because the purpose is explicitly stated as credential retrieval.
From the tool's definition Tool name 'get_db_credentials' and description 'Get the credentials for a SkySQL database instance' indicate retrieval of sensitive database credentials.
Documented attack patterns abuse exactly the kind of access get_db_credentials gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Skysql, and nothing reaches the server without passing your rules. This is the rule we recommend for get_db_credentials:
{
"version": "1",
"default": "deny",
"tools": {
"get_db_credentials": {}
}
}get_db_credentials is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the credentials for a SkySQL database instance. It is categorised as a Read tool in the Skysql MCP Server, which means it retrieves data without modifying state.
Register the Skysql MCP server in PolicyLayer and add a rule for get_db_credentials: 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 Skysql. Nothing to install.
get_db_credentials 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 get_db_credentials 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 get_db_credentials. 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.
get_db_credentials is provided by the Skysql MCP server (skysqlinc/skysql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Skysql, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
