Detect harmful drug interactions in a medication list.
AI agents call check_drug_interactions to retrieve information from MCPDischarge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads drug interaction data to inform clinical decision-making but does not create orders, dispense medications, modify records, delete data, or execute external operations. The blast radius of misuse is minimal—an agent could request checks on irrelevant medication lists, but cannot cause harm through the tool itself.
From the tool's definition Tool performs detection/checking of drug interactions without modifying data, patient records, or triggering any actions.
Attacks that exploit this kind of access
Detect harmful drug interactions in a medication list. It is categorised as a Read tool in the MCPDischarge MCP Server, which means it retrieves data without modifying state.
Register the MCPDischarge MCP server in PolicyLayer and add a rule for check_drug_interactions: 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 MCPDischarge. Nothing to install.
check_drug_interactions 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 check_drug_interactions 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 check_drug_interactions. 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.
check_drug_interactions is provided by the MCPDischarge MCP server (prashantsingh1234/mcp_project). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
