AhaSend — Claude Code MCP server: setup and features
AhaSend lets an AI agent send email, inspect delivery issues, and manage domains, templates, contacts, and campaigns through MCP.
claude mcp add --transport http mcp https://mcp.ahasend.com/mcpWhat AhaSend does
AhaSend exposes tools for sending messages, diagnosing failed delivery, and checking deliverability. An agent can also work with domains, templates, contacts, lists, campaigns, webhooks, routes, suppressions, SMTP credentials, and sub-accounts.
The server calls the AhaSend v2 API, while the API key scopes control which tools are available. List operations return pages of 20 items and allow up to 100; the returned cursor fetches the next page. You can use an HTTP MCP endpoint or build the Go module with a stdio transport.
Campaign sends require a person’s confirmation. A one-off send above MaxRecipientsPerSend, whose default is 50 recipients, is refused, so bulk email goes through a campaign instead.
What it helps with
- send an email through AhaSend
- diagnose why a message failed
- check a domain and its DNS records
- create and schedule a campaign
- manage contacts and mailing lists
Example prompts for the agent
- Send an AhaSend email to
[email protected]using the subject fromsubject.txt. - Find out why message
message_idwas not delivered. - List the AhaSend campaigns and schedule the selected one after I confirm the details.
