AI agents call impact_analysis to retrieve information from Tages without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs dependency analysis and reporting on stored memories without creating, modifying, deleting, or executing external operations. It is purely informational, retrieving and analyzing relationships between stored items. This is a read-only operation with minimal blast radius even if misused by an agent.
From the tool's definition Tool description states it 'Analyze the downstream impact of a memory' — a query or analysis operation with no modification of data. The verb 'analyze' and the focus on dependency inspection indicate data retrieval and inspection only.
Attacks that exploit this kind of access
Analyze the downstream impact of a memory — how many others depend on it. It is categorised as a Read tool in the Tages MCP Server, which means it retrieves data without modifying state.
Register the Tages MCP server in PolicyLayer and add a rule for impact_analysis: 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 Tages. Nothing to install.
impact_analysis 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 impact_analysis 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 impact_analysis. 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.
impact_analysis is provided by the Tages MCP server (ryantlee25-droid/tages). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
