Diagnose the connected service account\
AI agents call check_table_access to retrieve information from ServiceNow-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries or diagnoses access control information for the current service account. It is a read-only diagnostic operation that retrieves data about permissions and account status without side effects, making it a Read category tool. Severity is low because unauthorized disclosure of account access metadata poses minimal immediate risk compared to modification or deletion operations.
From the tool's definition Tool name 'check_table_access' and description 'Diagnose the connected service account' indicate a diagnostic query operation that retrieves information about access permissions and service account status without modifying or executing actions.

Register the ServiceNow- MCP server in PolicyLayer and add a rule for check_table_access: 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.
check_table_access 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 check_table_access 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 check_table_access. 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.
check_table_access 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.
