Triage your Missive inbox from Claude Desktop

This MCP Server lets Claude Desktop fetch your conversations using `list_conversations` and drill down into specific threads with `get_conversation` or `list_messages`. Your agent can instantly filter by mailboxes like assigned or closed. It handles the busywork of finding the exact thread you need to address next.

Draft and send collaborative emails

The `create_draft` tool allows Claude Desktop to write replies based on your conversation history. It creates drafts using `create_draft` and shoots them off with `send_draft` once you give the green light. You don't have to copy-paste context from your email client into the chat window anymore. Claude reads the thread, drafts the response, and saves it directly in your shared inbox.

Assign work and label conversations

The `create_post` tool keeps your team aligned without opening the web app by letting Claude trigger actions like closing threads. You can write comments, assign owners, or close out resolved issues in one go. We also make organizing your inbox on the fly incredibly easy. Let Claude Desktop fetch your setup via `list_labels` and apply the right tags to keep things clean.
