WHAT IT DOES

What calculate_infusion_rate does on Pharmacy MCP Server

AI agents invoke calculate_infusion_rate to trigger actions in Pharmacy MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why calculate_infusion_rate needs a policy

The tool executes a calculation algorithm to produce an IV infusion rate. While it does not modify stored data (ruling out Write/Destructive) or move money (ruling out Financial), it actively runs a computation with clinical significance. Misuse or incorrect inputs could yield dangerous dosing recommendations, warranting a medium severity.

From the tool's definition 'Calculate IV infusion rate' — performs a computation/calculation that triggers a derived output (infusion rate) based on clinical inputs, analogous to other calculate_* tools on this server that run dosing computations.

Verdict

calculate_infusion_rate Rate-limited

calculate_infusion_rate stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about calculate_infusion_rate

What does the calculate_infusion_rate tool do? +

Calculate IV infusion rate. It is categorised as a Execute tool in the Pharmacy MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on calculate_infusion_rate? +

Register the Pharmacy MCP Server MCP server in PolicyLayer and add a rule for calculate_infusion_rate: 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 Pharmacy MCP Server. Nothing to install.

What risk level is calculate_infusion_rate? +

calculate_infusion_rate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit calculate_infusion_rate? +

Yes. Add a rate_limit block to the calculate_infusion_rate 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.

How do I block calculate_infusion_rate completely? +

Set action: deny in the PolicyLayer policy for calculate_infusion_rate. 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.

What MCP server provides calculate_infusion_rate? +

calculate_infusion_rate is provided by the Pharmacy MCP Server MCP server (u9401066/pharmacy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
