Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Dead Simple Email — questions

Answers built from our own checks of this server.

What can Dead Simple Email do?
It exposes 14 tools, read directly from the server on our last check. Among them: create_inbox, delete_inbox, forward_message, get_usage, get_verification_code, get_verification_link and 8 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Dead Simple Email mostly used for?
Its tools cluster around inbox and verification. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Dead Simple Email working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 472 ms. The bar chart above shows every period we have measured.
How do I connect Dead Simple Email?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own key or an OAuth login: it refuses anonymous clients.
Does Dead Simple Email need an API key?
Yes. Every time we knock, Dead Simple Email answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Dead Simple Email?
It answers our handshake in 472 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Dead Simple Email?
The pypi package deadsimple-email was installed 1 104 times in the last week. Week over week that is +272%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Dead Simple Email open source?
Yes — it is published under the MIT licence, written in Python, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
