Missive's AI integration only has the api key input. But adding MCP capabilities to API based claude/gpt etc. is as easy as adding MCP server info along with the API calls Missive is already making.

This would enable the API based Missive AI to access anything with an MCP, like notion, project management software, even our own website backend to pull up customer data.

From a UI perspective this would be simple to add as an additional input next to the API key.
