Calculate weight-based dosage (mg/kg).
AI agents call calculate_dose_by_weight to retrieve information from Pharmacy MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a mathematical computation based on pharmaceutical dosing formulas. It retrieves or derives information (a dosage recommendation) from input data without creating, modifying, deleting, or executing any irreversible actions. The blast radius of misuse is minimal—an incorrect dosage calculation could lead to clinical errors if acted upon, but the tool itself has no write or destructive capability.
From the tool's definition Tool name is 'calculate_dose_by_weight' and description states 'Calculate weight-based dosage (mg/kg).' This is a pure calculation function that takes input parameters and returns a computed dosage value without modifying any data, executing external code, or…
Attacks that exploit this kind of access
Calculate weight-based dosage (mg/kg). It is categorised as a Read tool in the Pharmacy MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pharmacy MCP Server MCP server in PolicyLayer and add a rule for calculate_dose_by_weight: 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.
calculate_dose_by_weight 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 calculate_dose_by_weight 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 calculate_dose_by_weight. 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.
calculate_dose_by_weight 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.
