Connect Claude

Claude connects to anymail as a custom connector. You give it the URL, sign in to anymail in the browser and pick what Claude may do. No API key is involved.

You need a Claude plan with custom connectors: Pro, Max, Team or Enterprise.

Pro and Max#

  1. In Claude, open Customize, then Connectors.
  2. Select + Add, then Add custom connector.
  3. Enter the name anymail and the URL:

https://app.anymail.watch/api/mcp

  1. Continue. Claude detects the OAuth settings of anymail. Leave Authentication on a sign-in option and add no request headers.
  2. Select Add, then Connect. A browser window opens anymail.
  3. Sign in to anymail. On the consent screen pick the Workspace and the Access, then select Allow.

The connector shows as connected. Claude can now use the anymail tools in any chat where the connector is turned on.

Team and Enterprise#

An Owner adds the connector once for the organisation:

  1. Open Organization settings, then Connectors.
  2. Select Add, then Custom, then Web.
  3. Enter the name anymail and the URL https://app.anymail.watch/api/mcp, keep the detected OAuth settings and select Add.

Each member then opens Customize, Connectors, finds anymail and selects Connect. Every member signs in with their own anymail account, so each person reaches only the workspaces they belong to.

Choose the access#

Access on the consent screen What Claude can do
Read only Read campaigns, statistics, prospects, companies, replies, mailboxes and domains. Every write tool fails with insufficient_scope.
Read and write Everything above, and create campaigns, write steps, enrol prospects, start and stop campaigns, answer replies.

Start with Read only if you want reports and answers first. Connect again to change it.

The anymail tools carry annotations that mark reads, writes and destructive calls, so Claude can ask for your approval before a change. start_campaign and reply_to_message are also marked as reaching outside anymail, because they send email.

Try it#

Ask Claude:

  • "Which of my anymail campaigns has the best reply rate this month?"
  • "Show me unread interested replies and draft answers."
  • "Build a three-step campaign for the prospects at example.com, but do not start it."

The prompts of the server appear in the prompt menu of Claude as well.

Disconnect#

Remove or disconnect the connector in Customize, Connectors. Removing a person from the anymail workspace also ends their access at once.
