What nearest_power does on TinyFn
AI agents call nearest_power 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 |
|---|---|---|---|
base | integer | — | Base |
number | integer | Yes | Number to find nearest power for |
Parameters from the server's own tool schema.
Why nearest_power is rated Low
This is a deterministic mathematical utility that reads input parameters and returns a computed result. It has no capability to modify state, execute arbitrary code, delete data, or trigger external systems. The blast radius of misuse is negligible—incorrect mathematical output cannot harm systems or data.
From the tool's definition Tool performs a mathematical calculation ('Find the nearest power of a base to a number') with no side effects, no data modification, and no external operations triggered.
Attacks that exploit this kind of access
The rule that runs nearest_power 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 nearest_power, this is the rule to start with:
nearest_power 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 nearest_power call is checked against it from then on.
Questions about nearest_power
Find the nearest power of a base to a number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
nearest_power accepts 2 parameters: base, number. Required: number. 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 nearest_power: 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.
nearest_power 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 nearest_power 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 nearest_power. 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.
nearest_power 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.
