Agent Skills Library

Do this first: nothing on this page works until you add the AI Century Agent Skills Library connector to ChatGPT or Claude. It takes about two minutes, once.

Agent Skills

Ready-made agent skills that feed your own ChatGPT or Claude: image and video prompts for TikTok, Reels and Shorts. Add the connector once, then paste a skill's starter line and it gets to work.

How to add the AI Century Agent Skills Library Copy the MCP address, paste it into ChatGPT or Claude, then paste any skill's starter prompt. Three steps, about two minutes.

How to add the AI Century Agent Skills Library

Claude tutorial ChatGPT tutorial
What is an MCP? It is a one-time connection that lets ChatGPT or Claude read our agent skills library, a bit like giving it a library card. Without it, your assistant has never heard of a skill like AC21, so it will guess and invent something that looks right. With it, pasting a skill's ID hands your assistant the real instructions and reference files behind that skill. You add the connection once and it stays there for every skill on this page.

Paste it into ChatGPT or Claude
Add to Claude
Open Claude → Settings → Connectors → Add custom connector → paste the address → Add. There is nothing to sign in to. Then, in a chat, open the + menu → Connectors and switch it on. Free accounts hold one custom connector. Desktop, mobile and Claude in Chrome pick it up once it is added on the web. On a Team or Enterprise plan an Owner adds it for everyone under Organization settings → Connectors.
Open ChatGPT → Settings → Security and login → turn on Developer mode (older versions: Settings → Apps → Advanced settings). Then open chatgpt.com/plugins → + → give it a name → paste the address → No authentication → Create, and review the tool list.

Works on Plus, Pro, Business, Enterprise and Edu on the web. Not on Free, not on mobile, not in Voice. In a Business or Enterprise workspace an admin first allows custom servers under Workspace settings → Permissions & Roles → Connected data. Expect a warning that custom MCP servers introduce risk; that is normal.

In a terminal, run this once:
claude mcp add --transport http ai-century https://aicenturies.com/mcp
Or add it to the project's .mcp.json:
{"mcpServers":{"ai-century":{"type":"http","url":"https://aicenturies.com/mcp"}}}

Tool lists are cached: after a change on our side, run /mcp in Claude Code and reconnect.

Paste a starter prompt
Back in the chat, paste any skill's starter prompt. That one line is all it takes: it fetches the real skill and hands the chat over. From there you tell it what you want to make. Every skill below has its own line, ready to copy.
Start AC21 using the AI Century Agent Skills Library.
