What this is

iGPT Skills is a marketplace of Claude Code plugins that lets people ask plain-language questions about their email and get back grounded, structured answers — by role.

Each plugin targets a specific role (sales, finance, HR, ...) and ships:

• A tightly-scoped set of skills that each answer one focused question.
• An agent that handles broad, cross-skill questions and synthesizes a prioritized response.
• An MCP configuration that points at the iGPT backend at https://mcp.igpt.ai/.

A salesperson asking "who's waiting on a reply from me?", a finance lead asking "build me an expense report for May in USD", a researcher asking "what grant deadlines are coming up?", or a CSM asking "which customers should I be worried about?" — the right skill picks itself up and returns a clean, ready-to-act answer grounded in their actual email threads.

Who it's for

End users. Salespeople, customer success managers, finance leads, HR business partners, recruiters, executives, marketers, real estate agents, consultants, procurement leads, IT teams, researchers — anyone whose work runs through email.

Builders and integrators. Developers extending the plugins, customizing prompts and schemas, or integrating the iGPT API directly. Every skill's prompt and structured output schema is documented at the file level (plugins/<plugin>/skills/<skill>/SKILL.md) and reusable.

Quick start

Install one of the plugins and connect your email through iGPT. That's the whole setup.

Cowork (Claude desktop app)

1. Open the plugins section in Cowork. Search the marketplace for iGPT, or add from GitHub: paste igptai/skills (or the full URL https://github.com/igptai/skills).
2. Pick the plugin matching your role (e.g. igpt-sales).
3. Install. The first time you ask the plugin a question, you'll be prompted to sign in to iGPT (free account; OAuth in a browser; read-only email permissions).
4. Ask in plain language: "who's waiting on a reply?", "what grant deadlines are coming up?", "any compliance flags I should know about?"

Claude Desktop

Settings → Connectors → Add MCP Server → enter https://mcp.igpt.ai/ and complete OAuth.

Claude Code

/plugin marketplace add igptai/skills
/plugin install igpt-sales@igpt-skills   # or any plugin name

The plugin ships its own .mcp.json so the MCP server is registered for you. OAuth happens on first use.

Other MCP clients

Any Streamable-HTTP MCP client works. Point it at https://mcp.igpt.ai/ and use the prompts and JSON schemas from each SKILL.md directly.
