WHAT IT DOES

What create_subtitle does on Zype Com

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

Parameter	Type	Required	Description
`url`	string	—	URL to the subtitle file (SRT, VTT)
`active`	boolean	—	Whether the subtitle is active (default: true)
`language`	string	Yes	Language code, e.g., "en", "es", "fr" (required)
`video_id`	string	Yes	The video ID to add subtitle to (required)

Parameters from the server's own tool schema.

RISK

Why create_subtitle is rated Medium

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

RECOMMENDED RULE

The rule that runs create_subtitle safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Zype Com, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_subtitle, this is the rule to start with:

create_subtitle Rate-limited

create_subtitle 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Zype Com, apply this rule, and every create_subtitle call is checked against it from then on.
