發布方自己的服務：Ably MCP by usefulapi
託管的 MCP 伺服器，讓助理讀取 Missive 的郵件與團隊聊天會話、訊息、聯絡人和團隊，並可建立草稿、寄送郵件和更新會話。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。
把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。
閱讀 https://sourceweft.com/mcp/io.usefulapi%2Fmissive/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。把它新增到你客戶端的 mcpServers 設定中。

}Manage Missive collaborative email and chat from Claude, Cursor, or any MCP client — read conversations, messages, comments, drafts and contacts, and create drafts, send email, and update conversations. Hosted, no local install: connect with your Missive API token.
Live endpoint: https://missive.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://missive.usefulapi.io/mcp.claude mcp add --transport http missive https://missive.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Missive credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/missive/
On first connect you'll paste your Missive API token (Missive → Preferences → API → Create a new token; requires a Productive plan). It's validated, stored per-user, and scoped to you — no keys in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with missive_upgrade (it returns a Stripe Checkout link). Cancel any time with missive_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running missive_upgrade before then undoes the cancel. Or write to [email protected].
