What generate_uuids does on TinyFn
AI agents call generate_uuids to retrieve information from TinyFn without modifying anything. It is 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 |
Parameters from the server's own tool schema.
Why generate_uuids is rated Low
This tool produces random UUID values as output. It is a deterministic utility function (in the sense of no external side effects) that only returns generated identifiers. No data is read from a store, written, or deleted. It fits best under 'Read' as it retrieves/returns computed data without any side effects. Misuse risk is minimal.
From the tool's definition Generate random UUIDs — purely generates/returns data with no side effects, no external operations, no data modification.
Attacks that exploit this kind of access
The rule that runs generate_uuids safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For generate_uuids, this is the rule to start with:
generate_uuids is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every generate_uuids call is checked against it from then on.
Questions about generate_uuids
Generate random UUIDs. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
generate_uuids accepts 1 parameter: count. 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 generate_uuids: 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.
generate_uuids 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 generate_uuids 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 generate_uuids. 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.
generate_uuids 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.
