AI agents call format_date 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 |
|---|---|---|---|
date | string | Yes | Date string (ISO format) |
format | string | — | Output format |
Parameters from the server's own tool schema.
This tool performs string formatting on an input date—a pure computational operation that reads and transforms data deterministically without modifying state, executing code, or affecting external systems. It belongs in the Read category with low severity due to negligible security impact if misused by an AI agent.
From the tool's definition Tool name 'format_date' and description 'Format a date string' indicate data transformation/retrieval without side effects. No creation, modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Format a date string. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
format_date accepts 2 parameters: date, format. Required: date. 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_date: 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_date 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_date 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_date. 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_date 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_date 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.
