What unix_to_datetime does on TinyFn
AI agents call unix_to_datetime 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 |
|---|---|---|---|
timestamp | integer | Yes | Unix timestamp |
timezone_name | string | — | Timezone for output |
Parameters from the server's own tool schema.
Why unix_to_datetime is rated Low
This is a pure utility function that converts a numeric timestamp to a formatted datetime string. It has no capability to modify state, execute code, delete data, move money, or trigger external operations. It is deterministic (same input always produces same output) and read-only, making it low severity. The low confidence penalty (0.05) is minimal since the description is clear and unambiguous.
From the tool's definition Tool performs a deterministic conversion of Unix timestamp to datetime. The description explicitly states 'Convert Unix timestamp to datetime' - a read-only operation that retrieves/transforms existing data without side effects.
Attacks that exploit this kind of access
The rule that runs unix_to_datetime 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 unix_to_datetime, this is the rule to start with:
unix_to_datetime 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 unix_to_datetime call is checked against it from then on.
Questions about unix_to_datetime
Convert Unix timestamp to datetime. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
unix_to_datetime accepts 2 parameters: timestamp, timezone_name. Required: timestamp. 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 unix_to_datetime: 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.
unix_to_datetime 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 unix_to_datetime 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 unix_to_datetime. 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.
unix_to_datetime 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.
