suggest_table
AI agents call suggest_table to retrieve information from ServiceNow CMDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The empty description weakens confidence, but the tool name suggests a lookup/suggestion operation. The sibling tools are predominantly Read-category (analysis, queries, health checks, descriptions, path finding). No evidence suggests data creation, modification, execution, deletion, or financial operations. Classification as Read is the most reasonable inference given the CMDB context and peer tool patterns.
From the tool's definition Tool named 'suggest_table' with empty description. Contextual inference: sibling tools like 'analyze_configurables', 'check_connection', 'cmdb_health_summary', 'count_cis', 'describe_ci_class', 'find_ci_path', and 'find_duplicate_cis' are all read-only query…

suggest_table. It is categorised as a Read tool in the ServiceNow CMDB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow CMDB MCP Server MCP server in PolicyLayer and add a rule for suggest_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 CMDB MCP Server. Nothing to install.
suggest_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 suggest_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 suggest_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.
suggest_table is provided by the ServiceNow CMDB MCP Server MCP server (ketiil/mcp-cmdb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
