Get current user
AI agents call my_context 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.
This tool retrieves the authenticated user's context/identity information. It performs a read-only query with no ability to modify data, execute commands, or trigger external operations. The blast radius is minimal—it only exposes the current user's identity, which is typically already known to the authenticated session. Severity is low due to limited impact if misused.
From the tool's definition Tool name 'my_context' and description 'Get current user' indicate retrieval of user identity information without modification or side effects.
Attacks that exploit this kind of access
Get current user. 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 my_context: 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.
my_context 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 my_context 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 my_context. 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.
my_context is provided by the ServiceNow MCP Server MCP server (schwarztim/servicenow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
