AI agents call get_now 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.

Parameters from the server's own tool schema.
This tool performs a read-only operation to fetch the current system time and date. It does not modify, execute, delete, or create any data, nor does it trigger external operations or financial transactions. The retrieval of the current time is a deterministic, side-effect-free operation with minimal security risk even if misused by an agent.
From the tool's definition Tool name 'get_now' and description 'Get current date and time' indicate a simple query operation that retrieves the current timestamp without side effects.
Attacks that exploit this kind of access
Get current date and time. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
get_now accepts 1 parameter: tz. 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 get_now: 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.
get_now 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 get_now 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 get_now. 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.
get_now 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.
get_now 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.
