List all available SkySQL DB agents with their capabilities
AI agents call list_agents 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 performs a read-only enumeration of available agents and their metadata. It has no side effects, does not modify data, and does not execute operations. The action of listing/retrieving information fits squarely within the Read category. The severity is low because exposing agent names and basic capability metadata poses minimal direct risk.
From the tool's definition Tool name 'list_agents' and description 'List all available SkySQL DB agents with their capabilities' indicate a retrieval operation that queries and returns information about existing agents without modifying any data.
Documented attack patterns abuse exactly the kind of access list_agents 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 list_agents:
{
"version": "1",
"default": "deny",
"tools": {
"list_agents": {}
}
}list_agents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available SkySQL DB agents with their capabilities. 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 list_agents: 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.
list_agents 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 list_agents 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 list_agents. 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.
list_agents 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.
