AI agents call is_divisible to retrieve information from TinyFn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
number | integer | Yes | The number to check |
divisor | integer | Yes | The divisor |
Parameters from the server's own tool schema.
This is a deterministic mathematical validation tool that performs a read-only arithmetic check. It takes inputs and returns a boolean result with no side effects, no data modification, no external execution, and no destructive operations. It fits squarely in the Read category as a query/validation operation.
From the tool's definition Tool name 'is_divisible' and description 'Check if a number is divisible by another number' indicate a pure mathematical check that retrieves or queries a computational result without creating, modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Check if a number is divisible by another number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
is_divisible accepts 2 parameters: number, divisor. Required: number, divisor. 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 is_divisible: 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.
is_divisible 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 is_divisible 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 is_divisible. 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.
is_divisible 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.
is_divisible is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
