add_time_2 · TinyFn MCP: Risk & Policy

WHAT IT DOES

What add_time_2 does on TinyFn

AI agents use add_time_2 to create or update resources in TinyFn — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TinyFn environment.

Parameter	Type	Required	Description
`days`	integer	—	Days to add
`hours`	integer	—	Hours to add
`minutes`	integer	—	Minutes to add
`seconds`	integer	—	Seconds to add
`datetime_str`	string	Yes	Datetime in ISO format

Parameters from the server's own tool schema.

WHY IT NEEDS A POLICY

Why add_time_2 needs a policy

An AI agent can call add_time_2 faster than any human can review — one bad instruction and it creates or modifies resources in TinyFn by the hundred, each call as confident as the last.

Verdict

add_time_2 Rate-limited

add_time_2 stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
