Overview

AI-generated overview

MailKite's official MCP server lets an assistant send email, manage domains, DNS, webhooks, templates and inbound routing through the MailKite API.

What you can do
Send email over a verified domain and receive inbound mail as webhooks or routed inboxes, including an inbox agent that answers, files or escalates on its own. Manage sending domains and their DNS records. Configure webhooks, templates and inbound routing rules. Search the MailKite documentation. Each MailKite API method is exposed as one tool generated from the shared API contract.
When to use it
Use it when you want an assistant to operate a MailKite account directly: sending transactional or product email, setting up domains and DNS, wiring inbound mail to an agent inbox, or managing templates and webhooks from a chat or coding agent.
Requirements
Either the hosted remote endpoint with one-click OAuth, or the local npm package run with npx, which needs Node.js and a MailKite API key supplied in the MAILKITE_API_KEY environment variable. A MailKite account and a verified sending domain are needed to send mail.
Before you install
The API key (MAILKITE_API_KEY) is a live credential that grants access to the account; keep it out of shared configuration. Tools can send real email, change DNS records, and create or alter webhooks, templates and routing rules, so actions affect live mail delivery. Inbound routing can hand incoming mail to an agent that replies or escalates automatically.

Installation

In SourceWeft

  1. Open Mailkite in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.mailkite%2Fmailkite/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

[npm] [MailKite MCP server – quality and maintenance score on Glama]

Read-only mirror. This repo is a generated, release-time mirror of the MailKite monorepo (the private source of truth) — development doesn't happen here. Install from npm and open issues against the MailKite docs.

Install

{  "mcpServers": {    "mailkite": {      "command": "npx",      "args": ["-y", "@mailkite/mcp"],      "env": { "MAILKITE_API_KEY": "mk_live_…" }    }  }}

Tools

One tool per MailKite API method, generated from the shared contract. Full list + schemas: https://mailkite.dev/docs/libraries#mcp.

Use it from an AI agent — MCP + Agent connectors

MailKite speaks the Model Context Protocol: every API method is a tool your AI assistant (Claude, Cursor, …) can call — send mail, manage domains, search the docs, and give an agent its own inbox. Full guide: https://mailkite.dev/docs/ai-agents.

Hosted (recommended) — one-click OAuth, no key to copy:

bash
claude mcp add --transport http mailkite https://mcp.mailkite.dev/mcp

In Claude Code you can also install the plugin:

text
/plugin marketplace add mailkite/claude-code/plugin install mailkite@mailkite

Any chat/UI agent: "Add the MCP server at https://mcp.mailkite.dev/mcp and authenticate in the browser when prompted."

Local (static key, offline / CI):

json
{ "mcpServers": { "mailkite": { "command": "npx", "args": ["-y", "@mailkite/mcp"], "env": { "MAILKITE_API_KEY": "mk_live_…" } } } }

Give an agent its own inbox. Route inbound mail to a built-in inbox agent (the agent route action) and it answers, files, or escalates on its own — see https://mailkite.dev/docs/ai-agents.
