Query records from any ServiceNow table
AI agents call query_table to retrieve information from ServiceNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool is described as querying records, which is a read operation. However, 'any ServiceNow table' gives it broad access across all modules (incidents, CMDB, change records, user data, etc.), which increases the blast radius if misused to exfiltrate sensitive data. There is no indication it executes arbitrary SQL or performs writes, but the unrestricted table scope raises severity to medium.

Attacks that exploit this kind of access
Query records from any ServiceNow table. It is categorised as a Read tool in the ServiceNow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow MCP Server MCP server in PolicyLayer and add a rule for query_table: 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 Server. Nothing to install.
query_table 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 query_table 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 query_table. 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.
query_table is provided by the ServiceNow MCP Server MCP server (lokimcpuniverse/servicenow-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
