I wrote this JMAP MCP server that adds email management tools to Claude for searching, reading, and sending emails through FastMail and other JMAP providers in Deno!
One of those semi on topic comments about JMAP adoption: I’m still wishing for more providers implementing JMAP :(
An upcoming one is Thundermail, which will be based on Stalwart! A big win for JMAP, especially with Thunderbird planning to implement it. I hope there are some killer features, the platform control will most likely drive adoption.
Still, I would much prefer keeping my current provider (which doesn’t support JMAP). I don’t want to host my own mail, so I’m left wishing for an IMAP <-> JMAP bridge. I’m probably okay hosting stalwart on my infrastructure (still making it a critical component of me receiving e-mail, but I could easily fall back in the case of downtime... a compromise) mirroring my entire inbox. If this was easy to do, I might be developing a JMAP client (or at least toying around with it).
Interesting! I haven't. This MCP was really just about providing raw access to the underlying data (created it in an hour). Might have some interesting results with that.
remember, any search mcp that hits the public web is both an avenue for prompt injection, and a means of data exfiltration. good luck and may your password reset emails stay un-yeeted
