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.

Connect this server

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 1 min ago.

run in your terminal
claude mcp add mcp-server --transport http https://mcp.e2a.dev/mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-server": {
      "url": "https://mcp.e2a.dev/mcp"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp-server]
url = "https://mcp.e2a.dev/mcp"
.cursor/mcp.json
{
  "mcpServers": {
    "mcp-server": {
      "url": "https://mcp.e2a.dev/mcp"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "mcp-server": {
      "url": "https://mcp.e2a.dev/mcp"
    }
  }
}

This one needs environment variables set before it will start: E2A_API_KEY (e2a API key from https://e2a.dev), E2A_AGENT_EMAIL (Default agent inbox (e.g. [email protected]). Optional — single-agent accounts auto-resolve.), E2A_BASE_URL (Self-hosted e2a backend URL. Defaults to https://e2a.dev.). The author declared them in the registry entry; get the values from the project itself.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

e2a — email for AI agents — questions

Answers built from our own checks of this server.

Why is there no tool list for e2a — email for AI agents?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 97.8% of checks in the last 24 hours got a reply.
Is e2a — email for AI agents working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 92 checks got a reply (97.8%), average response time 549 ms. The bar chart above shows every period we have measured.
How do I connect e2a — email for AI agents?
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 sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.
How do you sign in to e2a — email for AI agents?
No API key is involved. e2a — email for AI agents answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.
How fast is e2a — email for AI agents?
It answers our handshake in 549 ms on average, which is faster than 25% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use e2a — email for AI agents?
The npm package @e2a/mcp-server was installed 53 times in the last week. Week over week that is +40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is e2a — email for AI agents open source?
Yes — it is published under the Apache-2.0 licence, written in Go, 190 stars on GitHub and 26 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
