Server details

Identifier: dev.mailkite/inbound-email
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Sep 16, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to mailkite.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

MailKite's hosted MCP server that lets an assistant send email, manage domains, search docs, and handle inbound mail as webhooks or agent inboxes.

What you can do: Send email and manage sending domains through MailKite
Receive inbound mail as webhooks: verify, parse, route and store messages
Give an agent its own inbox, with an agent route action that answers, files or escalates
Search the MailKite documentation
Call any MailKite API method, since tools are generated one per API method
When to use it: Useful when a product or agent workflow needs real email: transactional sending over a verified domain, inbound mail turned into structured webhooks, or an agent that reads and replies to its own inbox.
Requirements: Remote streamable HTTP endpoint at mcp.mailkite.dev with OAuth sign-in through the browser. A MailKite account and verified domain are needed for sending. The README also documents a local npm alternative using a MAILKITE_API_KEY environment variable.

Before you install

The server can send mail and change domain settings, so actions have real external effects. The local install path requires a MailKite API key in the environment; the hosted path uses OAuth instead. Inbound messages and routing rules are handled by MailKite's service.

Installation

In SourceWeft

Open Inbound Email in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
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%2Finbound-email/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.

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:

In Claude Code you can also install the plugin:

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_…" } } } }

{ "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.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
