Query the ServiceNow system log (syslog) to check for errors, warnings,
AI agents call query_syslog to retrieve information from Now Sdk Ext without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing log data from ServiceNow's system logs. The verb 'query' combined with the stated purpose of checking/reviewing logs confirms a read-only operation with no side effects, data modification, or command execution. The blast radius is minimal—an AI agent cannot damage systems or data through log queries alone.
From the tool's definition Tool name 'query_syslog' and description 'Query the ServiceNow system log (syslog) to check for errors, warnings' indicate data retrieval without modification or execution capabilities.
Documented attack patterns abuse exactly the kind of access query_syslog gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Now Sdk Ext, and nothing reaches the server without passing your rules. This is the rule we recommend for query_syslog:
{
"version": "1",
"default": "deny",
"tools": {
"query_syslog": {}
}
}query_syslog is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Query the ServiceNow system log (syslog) to check for errors, warnings,. It is categorised as a Read tool in the Now Sdk Ext MCP Server, which means it retrieves data without modifying state.
Register the Now Sdk Ext MCP server in PolicyLayer and add a rule for query_syslog: 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 Now Sdk Ext. Nothing to install.
query_syslog 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_syslog 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_syslog. 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_syslog is provided by the Now Sdk Ext MCP server (sonisoft-cnanda/now-sdk-ext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Now Sdk Ext, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
