What ideal_weight does on TinyFn
AI agents call ideal_weight to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

|---|---|---|---|
sex | string | Yes | Sex: male or female |
height_cm | number | Yes | Height in centimeters |
Parameters from the server's own tool schema.
Why ideal_weight is rated Low
This tool retrieves or computes a result based on input parameters (height, gender, etc.) without modifying any data, executing external commands, or triggering irreversible actions. It falls squarely into the Read category as a deterministic mathematical calculator. Severity is low because misuse poses no meaningful security or operational risk to systems or data.
From the tool's definition Tool name is 'ideal_weight' and description states 'Calculate ideal body weight using various formulas' — this is a pure calculation/query operation with no side effects, data modification, code execution, or destructive action.
Attacks that exploit this kind of access
The rule that runs ideal_weight safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ideal_weight, this is the rule to start with:
ideal_weight is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every ideal_weight call is checked against it from then on.
Questions about ideal_weight
Calculate ideal body weight using various formulas. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
ideal_weight accepts 2 parameters: sex, height_cm. Required: sex, height_cm. The full parameter table on this page comes from the server's own tool schema.
Register the TinyFn MCP server in PolicyLayer and add a rule for ideal_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 TinyFn. Nothing to install.
ideal_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 ideal_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 ideal_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.
ideal_weight is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
