retainful_upsert_contactWRITE: create a contact, or update it when the email or phone already exists. Does not add anyone to a list. email_opt_in is required: it sets marketing consent, so send SUBSCRIBED only with real consent. Needs email or phone. Retainful API: POST /customer/create.

GitHub 仓库最后更新于–,最新版本(1.1.3)于昨天进入注册中心。
支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

Use your Retainful account from Claude, Cursor, or any MCP client. Read contacts and lists, add contacts to lists, and record events. Hosted, no local install: connect with your own credentials.
Live endpoint: https://retainful.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://retainful.usefulapi.io/mcp.claude mcp add --transport http retainful https://retainful.usefulapi.io/mcp, then run /mcp to log in.{
"mcpServers": { "retainful": { "url": "https://retainful.usefulapi.io/mcp" } } }
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 Retainful credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/retainful/
On first connect you provide your Retainful API key, created in Retainful under Integrations → your app → Create API key. The server validates it and stores it per user. No keys go in config files.
