AI agents call get_alert_evidence 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 alert evidence and threat indicators from the SIEM system—a read operation with no side effects or data mutation. However, the severity is medium rather than low because evidence and indicators could contain sensitive information about security incidents, and inappropriate access or disclosure could inform an attacker about detection capabilities or internal investigations.
From the tool's definition Tool name 'get_alert_evidence' and description 'Get evidence and indicators associated with an InsightIDR alert' indicate retrieval of alert-related data without modification.
Attacks that exploit this kind of access
Get evidence and indicators associated with an InsightIDR alert. 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_alert_evidence: 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_alert_evidence 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_alert_evidence 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_alert_evidence. 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_alert_evidence 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.
