AI agents call get_lab_results to retrieve information from AgentCare without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves laboratory results from healthcare records without modifying data. Although incomplete, the naming convention and server context confirm it is a Read operation. Severity is high rather than low because lab results are sensitive PHI/medical data; misuse could expose private health information to unauthorized parties, though the tool itself performs no destructive or irreversible action.
From the tool's definition Tool name 'get_lab_results' and server description indicate retrieval of patient lab data from EMRs (Cerner, Epic). All sibling tools use 'get_' prefix indicating read-only queries.
Attacks that exploit this kind of access
Get patient. It is categorised as a Read tool in the AgentCare MCP Server, which means it retrieves data without modifying state.
Register the AgentCare MCP server in PolicyLayer and add a rule for get_lab_results: 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 AgentCare. Nothing to install.
get_lab_results 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_lab_results 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_lab_results. 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_lab_results is provided by the AgentCare MCP server (kartha-ai/agentcare-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
