MisarMail MCP Server

by Misar-AIversion 5.1.2i★ –iComputer or cloud
Registry nameio.github.Misar-AI/misarmail-mcp

Install

Overview

Description from the maker (original English)

Send transactional email, run campaigns, manage contacts and automations, audit deliverability.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Marketing & social media
  • You need to fill in: MISARMAIL_API_KEY, Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: MISARMAIL_API_KEY, MISARMAIL_BASE_URL, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "misarmail": {
      "command": "npx",
      "args": [
        "-y",
        "@misarmail/mcp"
      ],
      "env": {
        "MISARMAIL_API_KEY": "your-value",
        "MISARMAIL_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http misarmail https://api.misar.io/mail/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add misarmail --env MISARMAIL_API_KEY=your-value --env MISARMAIL_BASE_URL=your-value -- npx -y @misarmail/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "misarmail": {
      "url": "https://api.misar.io/mail/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "misarmail": {
      "command": "npx",
      "args": [
        "-y",
        "@misarmail/mcp"
      ],
      "env": {
        "MISARMAIL_API_KEY": "your-value",
        "MISARMAIL_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "misarmail": {
      "type": "http",
      "url": "https://api.misar.io/mail/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "misarmail": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@misarmail/mcp"
      ],
      "env": {
        "MISARMAIL_API_KEY": "your-value",
        "MISARMAIL_BASE_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • MISARMAIL_API_KEY secret env
    Your MisarMail API key (msk_…). Create one at https://mail.misar.io/developers, or omit it and run the "login" tool to authenticate via browser.
  • MISARMAIL_BASE_URL env
    Override the API base URL. Only needed for self-hosted instances.
  • Authorization secret required HTTP header
    MisarMail API key. Format: Bearer msk_… — create one at https://mail.misar.io/developers

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is MisarMail MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MISARMAIL_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (5.1.2) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: MCP YouTube Transcript, Google Analytics MCP, BibiGPT YouTube Video Summarizer

Install

Smithery (recommended)
npx -y @smithery/cli install misar/misarmail-mcp --client claude
Claude Code
claude mcp add misarmail -- npx -y @misarmail/mcp@latest
Manual (any client)
{

"mcpServers": { "misarmail": { "command": "npx", "args": ["-y", "@misarmail/mcp@latest"], "env": { "MISARMAIL_API_KEY": "msk_your_key_here" } } } }

Ready-made configs for every client live in connectors/.

Remote (no install)
{

"mcpServers": { "misarmail": { "type": "streamable-http", "url": "https://api.misar.io/mail/mcp", "headers": { "Authorization": "Bearer msk_your_key_here" } } } }


Authentication

Two options — no copy-paste needed for the first:

  1. Browser login. Start the server with no key and run the login tool. It opens the MisarMail consent screen, you review the requested permissions, and the key is delivered straight back and saved to ~/.misarmail/config.json.
  2. API key. Create one at https://mail.misar.io/developers and set MISARMAIL_API_KEY.

Self-hosted instances: set MISARMAIL_BASE_URL.

Agent skills

Bundled in skills/ — guidance an agent loads when a task matches.

SkillUse when
ab-test-campaignDesign and run an A/B test on a MisarMail campaign — subject line, content, sender name, or send time. Use for "A/B test", "split test", "which subject works better", or testing email variants.
audit-deliverabilityDiagnose why MisarMail emails land in spam or bounce, and produce a prioritized fix list. Use for "emails going to spam", "not being delivered", "low open rate", "domain reputation", DMARC/SPF/DKIM, or blocklist questions.
build-email-automationDesign and build a MisarMail automation workflow — welcome series, drip sequence, re-engagement, or onboarding. Use for "automate", "drip", "welcome series", "sequence", or trigger-based email.
clean-contact-listAudit and clean a MisarMail contact list — bounced, complained, and unengaged contacts. Use for list hygiene, re-engagement, suppression, or "why is my open rate falling".
email-performance-reportProduce a MisarMail performance report — opens, clicks, deliverability, revenue attribution. Use for "how are my emails doing", weekly/monthly reports, or campaign performance analysis.
run-email-campaignCreate, review, and send a bulk email campaign in MisarMail. Use when the user wants to email a list, newsletter, segment, or announcement to many recipients.
send-transactional-emailSend a one-off or transactional email through MisarMail. Use when the user asks to send, draft-and-send, or reply to an email — including receipts, notifications, welcome messages, and personal outreach.
setup-sending-domainAdd and verify a custom sending domain in MisarMail, including SPF, DKIM, DMARC, and inbound routing. Use for "send from my own domain", DNS setup, domain verification, or inbound email.

Safety

Destructive and irreversible actions are annotated (destructiveHint) so clients can prompt before running them. The skills instruct agents to confirm before anything that sends mail, publishes content, or is otherwise visible to other people.

Discovery (initialize, tools/list, prompts/list, resources/list) never requires credentials, so registries can index the server without one. Every action does.
