AI agents call get_body_measurements to retrieve information from Hevy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of the user's body measurement history. No data is created, modified, deleted, or used to trigger external actions. The blast radius of misuse is minimal—an attacker can only view fitness tracking data that is already stored in the user's Hevy account.
From the tool's definition Tool retrieves paginated list of body measurements with no modification capabilities. Uses pagination (page_size parameter) typical of read operations. Verb 'get' and noun 'measurements' indicate data retrieval.
Attacks that exploit this kind of access
Get a paginated list of body measurements. page_size max is 10. It is categorised as a Read tool in the Hevy MCP Server, which means it retrieves data without modifying state.
Register the Hevy MCP server in PolicyLayer and add a rule for get_body_measurements: 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 Hevy. Nothing to install.
get_body_measurements 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_body_measurements 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_body_measurements. 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_body_measurements is provided by the Hevy MCP server (srdjancodes/hevy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
