WHAT IT DOES

What run_query does on AWS Well-Architected Security Assessment Tool MCP Server

AI agents invoke run_query to trigger actions in AWS Well-Architected Security Assessment Tool MCP Server. 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.

Why run_query needs a policy

This tool permits execution of arbitrary SQL commands whose effects are entirely dependent on the query argument provided. While it could be Read-only (SELECT), Write (INSERT/UPDATE), or Destructive (DELETE/DROP) depending on the query, the tool itself enables Execute capability.

From the tool's definition Tool name is 'run_query' and description states it 'Run[s] a SQL query against Microsoft SQL Server'. SQL queries can execute arbitrary operations including data modification, deletion, or information disclosure depending on database permissions and query…

POLICY

How to control run_query

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Well-Architected Security Assessment Tool MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for run_query:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "run_query": {
      "limits": [
        {
          "counter": "run_query_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

run_query 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.

Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about run_query

What does the run_query tool do? +

Run a SQL query against Microsoft SQL Server. It is categorised as a Execute tool in the AWS Well-Architected Security Assessment Tool MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_query? +

Register the AWS Well-Architected Security Assessment Tool MCP Server MCP server in PolicyLayer and add a rule for run_query: 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 AWS Well-Architected Security Assessment Tool MCP Server. Nothing to install.

What risk level is run_query? +

run_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_query? +

Yes. Add a rate_limit block to the run_query 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.

How do I block run_query completely? +

Set action: deny in the PolicyLayer policy for run_query. 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.

What MCP server provides run_query? +

run_query is provided by the AWS Well-Architected Security Assessment Tool MCP Server MCP server (awslabs.well-architected-security-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS Well-Architected Security Assessment Tool MCP Server tool call.

Start from AWS Well-Architected Security Assessment Tool MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
