List OAuth application registry entries (client applications that can authenticate)
AI agents call list_oauth_applications 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 retrieves and displays OAuth application registry entries without modifying, executing, or deleting anything. While the data retrieved (client application credentials/configurations) is sensitive and could inform subsequent attacks, the tool itself performs only a read operation.
From the tool's definition Tool name contains 'list' and description states 'List OAuth application registry entries'; the verb 'list' indicates a retrieval operation with no side effects.
Attacks that exploit this kind of access
List OAuth application registry entries (client applications that can authenticate). It is categorised as a Read tool in the ServiceNow-MCP MCP Server, which means it retrieves data without modifying state.
Register the ServiceNow- MCP server in PolicyLayer and add a rule for list_oauth_applications: 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.
list_oauth_applications 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 list_oauth_applications 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 list_oauth_applications. 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.
list_oauth_applications 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.
