What is the Misarmail MCP MCP server?

Misarmail MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Misarmail MCP directly instead of describing what you should do. MisarMail MCP server — send email, run campaigns, manage contacts and automations, A/B test, and audit deliverability from Claude, Cursor, VS Code, Windsurf, and any MCP client.

What you get

Works with Claude (Desktop, Code, and web), Cursor, VS Code, Windsurf, Cline, Zed, Gemini CLI, ChatGPT, and any other MCP-compatible client — over stdio or Streamable HTTP.

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once Misarmail MCP is connected, these are the calls the assistant has available:

  • send_email — Send a transactional email from a verified MisarMail account
  • list_emails — List emails from a mailbox folder with optional full-text search across subject and body
  • get_email — Read the full content of a single email by ID, including headers, body, and attachments metadata
  • reply_to_email — Reply to an existing email thread
  • archive_email — Move an email to the archive folder
  • validate_email — Validate an email address before sending: syntax, MX records, disposable-domain and role-account detection
  • list_campaigns — List email marketing campaigns with their status, audience size, and headline metrics
  • get_campaign — Get full details for one campaign: content, audience segment, schedule, and delivery statistics (sent, opened, clicked, bounced, complained).
  • create_campaign — Create a new email marketing campaign as a draft
  • send_campaign — Send a campaign now, or schedule it for a future time by passing scheduled_at
  • list_contacts — List contacts with their subscription status and engagement metrics
  • create_contact — Add a single contact

Configuration and credentials

You will need 2 environment variables: MISARMAIL_API_KEY, MISARMAIL_BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Misarmail MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the misarmail mcp mcp server does with a few real requests.

Choosing this one

Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Misarmail MCP's toolset — send_email, list_emails, get_email and 11 more — is a fair guide to whether it matches your workflow. It is maintained by mrgulshanyadav; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
