Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

`check_balance`	Use before generating when you're unsure the key still has credits, or when the user asks about their plan, tier, or expiry. Shows remaining API credits, key tier, and expiry.
`generate_captions`	Use when the user wants ready-to-post social captions — hooks, post bodies, CTAs, and hashtags as JSON for LinkedIn, Instagram, TikTok, or X. Deterministic template engine (no LLM): best for on-brand, repeatable captions, not open-ended creative writing. tone: warm \| bold \| professional \| playful platform: linkedin \| instagram \| tiktok \| x count: 1-10 captions. Costs 1 API credit per call.
`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 convert to paid. The key is shown ONCE — save it as CAPTIONPACK_API_KEY immediately.

Schemas: list_tools.
