WHAT IT DOES

What run_aggregate_query does on ServiceNow-MCP

AI agents invoke run_aggregate_query to trigger actions in ServiceNow-MCP. 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.

RISK

Why run_aggregate_query is rated High

This tool executes queries against ServiceNow tables with user-controlled parameters. While read-only in nature (aggregation queries don't modify data), the Execute category applies because it runs code/queries whose effects and results are argument-dependent.

From the tool's definition Tool description states 'Run a grouped aggregate (COUNT, SUM, AVG) query on any table' with access to `/api/now/stats/{table}`.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs run_aggregate_query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_aggregate_query, this is the rule to start with:

run_aggregate_query Rate-limited

run_aggregate_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.

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ServiceNow-MCP, apply this rule, and every run_aggregate_query call is checked against it from then on.

FAQ

Questions about run_aggregate_query

What does the run_aggregate_query tool do? +

Run a grouped aggregate (COUNT, SUM, AVG) query on any table (latest release: /api/now/stats/{table}). It is categorised as a Execute tool in the ServiceNow-MCP 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_aggregate_query? +

Register the ServiceNow MCP server in PolicyLayer and add a rule for run_aggregate_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 ServiceNow-MCP. Nothing to install.

What risk level is run_aggregate_query? +

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

Can I rate-limit run_aggregate_query? +

Yes. Add a rate_limit block to the run_aggregate_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_aggregate_query completely? +

Set action: deny in the PolicyLayer policy for run_aggregate_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_aggregate_query? +

run_aggregate_query is provided by the ServiceNow MCP server (tedorigawa001/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
