Ask a question to a specific DB agent
AI agents invoke ask_agent to trigger actions in Skysql. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
Asking an AI database agent a question triggers external execution by that agent, which may run queries, modify data, or perform other database operations depending on what the agent is capable of. Since the effects depend on the natural language arguments passed and the agent's capabilities (which could include write or destructive operations), this falls under Execute.
From the tool's definition 'Ask a question to a specific DB agent' — triggers an AI-powered database agent that can interact with the database based on natural language input
Documented attack patterns abuse exactly the kind of access ask_agent 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 ask_agent:
{
"version": "1",
"default": "deny",
"tools": {
"ask_agent": {
"limits": [
{
"counter": "ask_agent_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}ask_agent stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Ask a question to a specific DB agent. It is categorised as a Execute tool in the Skysql MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Skysql MCP server in PolicyLayer and add a rule for ask_agent: 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.
ask_agent is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ask_agent 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 ask_agent. 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.
ask_agent 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.
