AI agents call lookup_epc to retrieve information from Homedata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
EPC data lookup is a read operation that retrieves historical energy efficiency information about a property. It has no side effects, does not modify data, and does not trigger external actions. Confidence is slightly reduced due to empty tool description, but the server context and naming pattern strongly indicate this is a straightforward query tool.
From the tool's definition Tool name 'lookup_epc' and server context indicate querying EPC (Energy Performance Certificate) data from the Homedata API.
Attacks that exploit this kind of access
lookup_epc. It is categorised as a Read tool in the Homedata MCP Server, which means it retrieves data without modifying state.
Register the Homedata MCP server in PolicyLayer and add a rule for lookup_epc: 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 Homedata. Nothing to install.
lookup_epc 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 lookup_epc 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 lookup_epc. 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.
lookup_epc is provided by the Homedata MCP server (wehomemove/homedata-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
