AI agents call factorial 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.

Parameters from the server's own tool schema.
This is a deterministic mathematical function that reads input and returns a computed result. It performs no I/O, makes no modifications to any state, executes no external code, and has no financial implications. It is purely a read-only computation operation, consistent with the sibling tools on this server (math, conversion, validation, hashing, encoding operations).
From the tool's definition Tool name 'factorial' and description 'Calculate the factorial of a number' indicate a pure mathematical computation with no side effects, no data modification, and no external operations.
Attacks that exploit this kind of access
Calculate the factorial of a number. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
factorial accepts 1 parameter: 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 factorial: 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.
factorial 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 factorial 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 factorial. 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.
factorial 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.
factorial 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.
