AI agents call random_uuid 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 | — | Number of UUIDs to generate |
version | integer | — | UUID version (1 or 4) |
Parameters from the server's own tool schema.
This tool generates random identifiers for use by the caller. It retrieves/produces output data without creating, modifying, deleting, or executing external operations. It has no blast radius if misused—a malicious agent generating many UUIDs causes no harm. Categorized as Read (data generation/retrieval with no side effects).
From the tool's definition Tool name 'random_uuid' and description 'Generate random UUID(s)' indicates data generation with no side effects, no modifications to system state, and no external operations triggered.
Attacks that exploit this kind of access
Generate random UUID(s). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
random_uuid accepts 2 parameters: count, version. 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_uuid: 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_uuid 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_uuid 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_uuid. 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_uuid 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_uuid 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.
