AI agents call viral_remix to retrieve information from Hooklayer without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though viral_remix only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access viral_remix gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Take a viral source video and produce a fresh script that mirrors its viral DNA — same scene structure, same energy pattern, different topic. Returns the extracted formula, scene-by-scene script, camera shots, text overlays, and a verify_hook block prompting you to score the generated hook via score_hook. USE WHEN the user finds a video they want to copy the structure of, or chained from analyze_account.recommended_chain. Pass EITHER source_url (auto-extracts transcript) OR transcript directly — one is required. Costs 3 credits. NO SELF-RATING: viral_remix deliberately does NOT return a self-rated hook score. The script generator rating its own hook is structurally invalid (cardinal coupling). After every viral_remix call, you MUST call score_hook with the verify_hook.hook_text to get a structurally-independent quality signal before reporting to the user. Skipping this step is hiding the self-grading loop.. It is categorised as a Read tool in the Hooklayer MCP Server, which means it retrieves data without modifying state.
Register the Hooklayer MCP server in PolicyLayer and add a rule for viral_remix: 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 Hooklayer. Nothing to install.
viral_remix 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 viral_remix 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 viral_remix. 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.
viral_remix is provided by the Hooklayer MCP server (https://hooklayer.dev/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
