Mailtea official MCP server documentation Agent Plugin skills separate installation Mailtea email website design skills

💡 Result:

Mailtea’s official docs distinguish **three installation options**:

- **Plugin package (MCP + skills):** One install gives an agent the MCP server and three skills: `mailtea-email`, `mailtea-email-design`, and `mailtea-site-design`. The site-design skill builds or restyles publication websites, saving changes as drafts. ([docs.mailtea.app](https://docs.mailtea.app/docs/documentation/agent-plugin?utm_source=openai))
- **MCP only:** Add the hosted server directly at `https://api.mailtea.app/mcp`. This gives the agent tools, **not the skills**. The docs provide separate client setup instructions. ([docs.mailtea.app](https://docs.mailtea.app/docs/documentation/agent-plugin?utm_source=openai))
- **Skills only:** The Agent Plugin page says skills-only and MCP-only paths are supported, but the retrieved documentation doesn’t establish the exact skills-only install command. ([docs.mailtea.app](https://docs.mailtea.app/docs/documentation/agent-plugin?utm_source=openai))

So, if you want email and website-design skills together with MCP, install the plugin; if you want only MCP tools, configure the server separately. The official [Agent Plugin docs](https://docs.mailtea.app/docs/documentation/agent-plugin) and [MCP Server docs](https://docs.mailtea.app/docs/documentation/mcp-server) have the setup details.

Clarify that the skills require a separate installation.

This entry installs only the Remote MCP configuration. It does not install the Mailtea Agent Plugin or its email and website-design skills. State that users must install the Agent Plugin separately, or remove the skills claim.

Review comment at @src/assets/marketplace/mcps.yml around lines 1554 - 1556:
Update the Mailtea entry’s description to remove the claim that it includes
email and website-design skills, or clarify that users must install the Agent
Plugin separately; keep the description limited to capabilities provided by the
Remote MCP configuration.
