AI agents call get_user_activity to retrieve information from Rapid7 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 user behavior analytics from the SIEM system. It reads historical data about user activities, login patterns, and system access. There are no side effects, data modifications, deletions, code execution, or financial implications. The tool fits the Read category profile: passive data retrieval for investigation purposes with no capability to alter system state.
From the tool's definition Tool description explicitly states 'Get user behavior analytics data: login times, locations, accessed assets, and anomalies' - uses the verb 'Get' and describes retrieval of existing analytics data without modification or deletion.
Attacks that exploit this kind of access
Get user behavior analytics data: login times, locations, accessed assets, and anomalies. It is categorised as a Read tool in the Rapid7 MCP Server, which means it retrieves data without modifying state.
Register the Rapid7 MCP server in PolicyLayer and add a rule for get_user_activity: 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 Rapid7. Nothing to install.
get_user_activity 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 get_user_activity 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 get_user_activity. 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.
get_user_activity is provided by the Rapid7 MCP server (solomonneas/rapid7-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
