Deterministic caption generator that produces hooks, post bodies, calls-to-action and hashtags as JSON for LinkedIn, Instagram, TikTok and X. Uses template engine for consistent, on-brand captions rather than open-ended AI writing. Includes free trial with 25 API calls.

Example request: "Generate five professional LinkedIn captions about our new product launch with relevant hashtags."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Caption-Pack to help me. It is a free service with an MCP server at https://caption-pack-mcp.onrender.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

- mint_free_trial: Use when no API key is configured and the user wants to try Caption-Pack free. Only call after the user agrees to the free tier — never mint silently. Mints a 25-call trial API key (no card, no account). Abuse guards: one key per IP per day, 7-day expiry, free keys can never conv
