AI agents call random_mac 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 MAC addresses to generate |
separator | string | — | Separator: :, -, or none |
uppercase | boolean | — | Use uppercase letters |
Parameters from the server's own tool schema.
This tool generates random MAC addresses, which is a deterministic data generation operation. It retrieves/generates output data without modifying system state, creating external side effects, executing code, or affecting financial systems. It fits the 'Read' category as a data retrieval/generation operation with no destructive or state-modifying consequences.
From the tool's definition Tool name 'random_mac' and description 'Generate random MAC address(es)' indicate generation of data with no side effects, no modifications to external systems, and no execution or deletion of data.
Attacks that exploit this kind of access
Generate random MAC address(es). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
random_mac accepts 3 parameters: count, separator, uppercase. 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_mac: 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_mac 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_mac 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_mac. 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_mac 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_mac 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.
