How do I install the MisarMail MCP Server MCP server?

Install it with Smithery, Claude Code, or a manual MCP configuration using `npx -y @misarmail/mcp@latest`. Set `MISARMAIL_API_KEY` for API-key authentication, or start without a key and use the browser login flow. Remote use is also available through the documented Streamable HTTP endpoint.

Does MisarMail MCP Server work with Cursor?

Yes, MisarMail MCP Server works with Cursor. The repository states that it supports Cursor over stdio or Streamable HTTP, and provides ready-made configurations in its `connectors/` directory.

How do I configure MisarMail MCP Server for a self-hosted instance?

Set `MISARMAIL_BASE_URL` to the self-hosted MisarMail address. Authentication can use a MisarMail API key through `MISARMAIL_API_KEY`, while remote deployments can send the key as a bearer token in the Streamable HTTP configuration.

Can MisarMail MCP Server schedule email campaigns?

Yes, it can schedule campaigns. Create a campaign as a draft, then call `send_campaign` with a future `scheduled_at` value; the same tool can send a campaign immediately.

How MisarMail MCP Server works

What MisarMail MCP Server MCP server does

The MisarMail MCP Server MCP server exposes MisarMail email and marketing operations to AI assistants. It supports transactional messages, mailbox access, replies, archiving, and address validation. Marketing workflows include campaign creation and scheduling, contact management, reusable templates, automation workflows, A/B testing, and signup-form data.

Analytics tools report delivery and engagement metrics such as sent, delivered, opened, clicked, bounced, complained, replied, and unsubscribed. The service also provides campaign reporting, revenue attribution, newsletter monetization statistics, deliverability scoring, DNS checks, domain management, and warm-up status. Inbox conversation tools and AI email categorization are available in the documented tool set.

How it works

Agents call MCP tools through either a local process or a remote Streamable HTTP endpoint. Local configuration runs the published npm package with npx; remote configuration points to MisarMail's MCP URL and sends a bearer token. The server can authenticate through a browser consent flow when started without an API key, or through a key created in the MisarMail developer area.

Campaigns can be created as drafts, sent immediately, or scheduled with a future timestamp. Automation workflows are created paused and can then be activated or paused. Contact imports accept up to 5,000 contacts in one call. Template tools can render sample variables into HTML and a subject before sending.

Setup and configuration

The MisarMail MCP Server MCP server supports installation through Smithery, a Claude Code command, or a manual MCP configuration. The local setup uses the @misarmail/mcp npm package and the MISARMAIL_API_KEY environment variable. Browser authentication stores its configuration in ~/.misarmail/config.json, avoiding manual key entry after consent.

For a self-hosted MisarMail instance, set MISARMAIL_BASE_URL. Remote use does not require a local package installation; configure the Streamable HTTP transport at https://api.misar.io/mail/mcp and provide an Authorization bearer header. Ready-made client configurations are available in the repository's connectors/ directory.
