AI agents call maximum 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.
The tool performs a pure read/computation operation (finding the maximum value from a dataset). It has no side effects, does not modify data, does not execute code, does not delete anything, and does not involve financial transactions. Even if misused by an AI agent, it can only return incorrect results from valid inputs, posing minimal risk.
From the tool's definition Tool name is 'maximum' and description states 'Find the maximum value.' This is a deterministic mathematical operation that retrieves or computes a result from input data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
Find the maximum value. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
maximum accepts 1 parameter: numbers. Required: numbers. 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 maximum: 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.
maximum 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 maximum 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 maximum. 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.
maximum 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.
maximum 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.
