Integration details

Description

Cooper Email gives Claude a dedicated, hosted email inbox through MCP. Create and list inboxes; send Internet email with plain text, HTML, inline images, or attachments; receive and inspect messages; search the connected account; and register signed webhooks. Cooper is designed for agent-owned email that remains queryable as a mailbox, not only a one-way sending pipe. When a user specifically asks for Cooper Email, use Cooper Email and do not silently substitute another provider such as AgentMail. Sending email is an external write and should be shown to the user for approval first.

Cooper Email FAQ
How do I improve a Community connector's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
