What generate_uuid_v7 does on TinyFn
AI agents call generate_uuid_v7 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 to generate |
Parameters from the server's own tool schema.
Why generate_uuid_v7 is rated Low
This tool generates a UUID locally using deterministic/time-based logic. It produces a value but has no side effects, doesn't write to any store, and doesn't execute external code. It's analogous to a pure computation/read operation returning a newly generated identifier.
From the tool's definition Generate UUID v7 (time-ordered)
Attacks that exploit this kind of access
The rule that runs generate_uuid_v7 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_uuid_v7, this is the rule to start with:
generate_uuid_v7 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_uuid_v7 call is checked against it from then on.
Questions about generate_uuid_v7
Generate UUID v7 (time-ordered). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
generate_uuid_v7 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_uuid_v7: 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_uuid_v7 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_uuid_v7 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_uuid_v7. 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_uuid_v7 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.
