Sessy MCP Server: Setup for Claude Code, Cursor and Other Apps

• Lists your email sources with 30-day health

  Shows each source (one per app or mail stream) with messages sent in the last 30 days, bounce rate and time of the latest event. Other tools take a source ID from this list.

  Try: “Which of my email sources have the highest bounce rate this month?”

• Finds sends, bounces, complaints, opens and clicks

  Searches email events newest first, by recipient address or subject, event type, bounce subtype and date range. It defaults to the last 30 days and returns up to 100 rows per page.

  Try: “Find all bounces to gmail.com addresses in the last week.”

  Read · search_events

• Shows one email's full delivery timeline

  Looks up a single email by its SES message ID and returns subject, sender, recipients, tags and every event per recipient, including bounce and complaint diagnostics.

  Try: “Show me what happened to message 0100018f-example.”

  Read · get_message

• Counts and rates for a source or the whole account

  Returns totals for sent, delivered, bounced, complaints, opens and clicks, plus rates, a bounce breakdown and an optional day-by-day series for up to 120 days.

  Try: “Give me last month's delivery and complaint rates for the newsletter source.”

• Shows the AWS wiring details for a source

  Returns a source's settings plus what you need on the AWS side: the webhook URL for the SNS subscription, suggested configuration set and topic names, and the remaining setup steps.

  Try: “What do I still need to set up in SES for the billing source?”

  Read · get_source_setup

• Creates a new email source and returns setup steps

  Adds a source with a name and optional badge color, then returns the SES wiring details. Calling it twice with the same name creates two sources.

  Try: “Create a source called 'Mobile app' and tell me how to connect SES.”

  Write · create_source

• Renames a source or changes its color

  Changes only the name or badge color of an existing source. Retention settings and deletion are not available through the server.

  Try: “Rename source 3 to 'Marketing emails'.”

  Write · update_source

Watch out for

• One API key reaches all of the account's email data

  The Sessy docs say a key grants access to all email data in the account and can create and rename sources. Treat it like a password and revoke unused keys. github.com

• It can create and rename sources

  create_source and update_source change source names and colors only. Retention settings and deleting sources are not offered and stay in the web UI. github.com

• Email text comes from other people

  Subjects, recipient addresses and bounce messages are third-party content. The server tells the assistant to treat them as data, but review any source change the assistant proposes. github.com

• Rate limits apply

  The endpoint allows 60 requests a minute per key and 10 a minute for invalid keys. github.com
