What convert_temperature does on Calcgrid
AI agents use convert_temperature to create or update resources in Calcgrid, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Calcgrid environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
value | number | Yes | Amount to convert, expressed in from_unit. |
to_unit | string | Yes | Unit to convert into (same symbols as from_unit). |
from_unit | string | Yes | Unit of the input value. Accepted symbols: C, F, K, R; spelled-out names and common abbreviations are accepted too. |
Parameters from the server's own tool schema.
Why convert_temperature is rated Medium
An AI agent can call convert_temperature faster than any human can review: one bad instruction and it creates or modifies resources in Calcgrid by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs convert_temperature safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Calcgrid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For convert_temperature, this is the rule to start with:
convert_temperature stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Calcgrid, apply this rule, and every convert_temperature call is checked against it from then on.
Questions about convert_temperature
Use this when you need a weather, cooking, body or laboratory temperature in another scale, e.g. Fahrenheit to Celsius or Celsius to Kelvin. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need to convert a temperature difference (a change of 10 °C is 18 °F, not 50 °F: multiply by 9/5 without the offset) or heat energy (use energy). What it computes: Converts temperatures between Celsius, Fahrenheit, Kelvin and Rankine with the exact defining relations (°F = °C × 9/5 + 32, K = °C + 273.15, °R = °F + 459.67) and rejects values below absolute zero. Inputs: value (number); from_unit (enum); to_unit (enum). Complete JSON argument examples: {"value":100,"from_unit":"F","to_unit":"C"} | {"value":25,"from_unit":"C","to_unit":"F"} Outputs: result, result_text, formula, factor, conversion_table. Formula: °F = °C × 9/5 + 32; °C = (°F − 32) × 5/9; K = °C + 273.15; °R = °F + 459.67 = K × 9/5 Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/temperature with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/conversion/temperature.md. It is categorised as a Write tool in the Calcgrid MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
convert_temperature accepts 3 parameters: value, to_unit, from_unit. Required: value, to_unit, from_unit. The full parameter table on this page comes from the server's own tool schema.
Register the Calcgrid MCP server in PolicyLayer and add a rule for convert_temperature: 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 Calcgrid. Nothing to install.
convert_temperature is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the convert_temperature 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 convert_temperature. 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.
convert_temperature is provided by the Calcgrid MCP server (https://tttkmbb.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
