WHAT IT DOES

What generate_captions does on EasyBits

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

RISK

Why generate_captions is rated Medium

Creates modified video with burned-in captions; reversible processing that generates new media output.

From the tool's definition Enqueue, transcribes, marks keywords, renders, burns-in animated captions

RECOMMENDED RULE

The rule that runs generate_captions safely

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

generate_captions Rate-limited

generate_captions 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 EasyBits, apply this rule, and every generate_captions call is checked against it from then on.

FAQ

Questions about generate_captions

What does the generate_captions tool do? +

Enqueue viral MrBeast-style animated captions for a video. Input: a public HTTPS URL to an MP4 / MOV / any common video format (iPhone HEVC supported). The service transcribes via Whisper, marks keywords + emojis with Claude Haiku, and renders 1080x1920-ish vertical (or matching source aspect) MP4 with burned-in animated captions (Bangers font, thick stroke, drop-shadow sticker, scale-overshoot pop, instant color switch). ASYNC: returns { jobId, status } immediately; poll get_caption_status until status is. It is categorised as a Write tool in the EasyBits MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on generate_captions? +

Register the EasyBits MCP server in PolicyLayer and add a rule for generate_captions: 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 EasyBits. Nothing to install.

What risk level is generate_captions? +

generate_captions is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit generate_captions? +

Yes. Add a rate_limit block to the generate_captions 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.

How do I block generate_captions completely? +

Set action: deny in the PolicyLayer policy for generate_captions. 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.

What MCP server provides generate_captions? +

generate_captions is provided by the EasyBits MCP server (@easybits.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
