AI agents call random_float 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 |
|---|---|---|---|
count | integer | — | How many numbers to generate |
max_val | number | — | Maximum value |
min_val | number | — | Minimum value |
decimals | integer | — | Decimal places |
Parameters from the server's own tool schema.
Generating random floats is a pure computational operation that retrieves/produces data without creating, modifying, deleting, or executing external operations. It has no blast radius if misused by an AI agent—the worst outcome is receiving unexpected numerical values. This is consistent with the server's purpose of providing deterministic utility tools.
From the tool's definition Tool name 'random_float' and description 'Generate random float(s)' indicate data generation with no side effects, no state modification, and no external impact.
Attacks that exploit this kind of access
Generate random float(s). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
random_float accepts 4 parameters: count, max_val, min_val, decimals. 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 random_float: 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.
random_float 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 random_float 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 random_float. 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.
random_float 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.
random_float 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.
