Executes a read-only SELECT query against the database - args: keyspace, query
AI agents invoke executeQuery to trigger actions in AWS Transform 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.
While a SELECT query is nominally read-only and safer than write/destructive operations, the Execute category applies because (1) the tool runs code (SQL queries) whose effects depend on arguments, and (2) arbitrary query execution can still cause harm via resource exhaustion, unauthorized data access, or timing-based attacks. Read category should be reserved for simpler data retrieval without code execution.
From the tool's definition The tool is named 'executeQuery' and executes a 'SELECT query against the database'. Although described as 'read-only', the ability to execute arbitrary queries against a database is an Execute action because query execution can have side effects (resource…
Documented attack patterns abuse exactly the kind of access executeQuery gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Transform MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for executeQuery:
{
"version": "1",
"default": "deny",
"tools": {
"executeQuery": {
"limits": [
{
"counter": "executequery_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}executeQuery 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.
Free to start. No card required.
Executes a read-only SELECT query against the database - args: keyspace, query. It is categorised as a Execute tool in the AWS Transform MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the AWS Transform MCP Server MCP server in PolicyLayer and add a rule for executeQuery: 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 Transform MCP Server. Nothing to install.
executeQuery 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 executeQuery 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 executeQuery. 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.
executeQuery is provided by the AWS Transform MCP Server MCP server (awslabs.aws-transform-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS Transform MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
