AI agents call format_relative_time 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 |
|---|---|---|---|
seconds | integer | Yes | Seconds from now (positive = future, negative = past) |
Parameters from the server's own tool schema.
This tool performs deterministic text formatting of time values into human-readable relative time strings. It is a read-only transformation with no ability to modify, delete, execute, or access external systems. The tool falls squarely in the Read category as it retrieves/transforms data without side effects.
From the tool's definition Tool description: 'Format seconds as relative time (e.g., '2 hours ago', 'in 3 days').' This is a pure formatting/conversion function that takes input data and returns a formatted string representation without any side effects, data modification, or external…
Attacks that exploit this kind of access
Format seconds as relative time (e.g., '2 hours ago', 'in 3 days'). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
format_relative_time accepts 1 parameter: seconds. Required: seconds. 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 format_relative_time: 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.
format_relative_time 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 format_relative_time 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 format_relative_time. 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.
format_relative_time 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.
format_relative_time 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.
