What celsius_to_kelvin does on TinyFn
AI agents call celsius_to_kelvin 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
celsius | number | Yes | Temperature in Celsius |
Parameters from the server's own tool schema.
Why celsius_to_kelvin is rated Low
This is a deterministic conversion utility that takes a temperature value and returns a converted result. It performs no I/O, creates no persistent state, executes no external operations, and cannot modify or delete data. It is purely a read-only computational function, consistent with the 500+ deterministic tools described for the TinyFn server (math, conversion, validation, hashing, encoding, date/time utilities).
From the tool's definition Tool name 'celsius_to_kelvin' and description 'Convert Celsius to Kelvin' indicate a pure mathematical conversion function that retrieves or transforms data without side effects.
Attacks that exploit this kind of access
The rule that runs celsius_to_kelvin 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 celsius_to_kelvin, this is the rule to start with:
celsius_to_kelvin 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 celsius_to_kelvin call is checked against it from then on.
Questions about celsius_to_kelvin
Convert Celsius to Kelvin. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
celsius_to_kelvin accepts 1 parameter: celsius. Required: celsius. 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 celsius_to_kelvin: 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.
celsius_to_kelvin 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 celsius_to_kelvin 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 celsius_to_kelvin. 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.
celsius_to_kelvin 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.
