Overview

Description from the maker (original English)

Email inboxes, webhooks, mock APIs, 2FA codes, approvals and 170 tools for AI agents.

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: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email
  • You need to fill in: Authorization

Install

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

Before you install

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

You need

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.

Run this in your terminal

claude mcp add --transport http socket-help https://socket.help/mcp --header 'Authorization: your-value'

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": {
    "socket-help": {
      "url": "https://socket.help/mcp",
      "headers": {
        "Authorization": "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": {
    "socket-help": {
      "type": "http",
      "url": "https://socket.help/mcp",
      "headers": {
        "Authorization": "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

  • Authorization secret HTTP header
    Optional. Bearer workspace key from socket.help; without it, anonymous limits apply.

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

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • add_authenticator

    Store a TOTP authenticator for an account your human asked you to create or operate. Requires an approved workspace key. Provide name and one of uri (otpauth://totp), secret (Base32), or imageBase64 (PNG/JPEG QR, at most 1 MiB and one million pixels). Secrets are encrypted and ne

  • list_authenticators

    List workspace authenticators without secrets. Use only for accounts your human asked you to create or operate.

  • delete_authenticator

  • get_email_attachment

  • inspect_webhook_inbox

    Read a webhook inbox and captured requests using its private token.

  • wait_for_webhook

    Block until a webhook inbox receives a request, then return the new requests. Pass after (the last request ID you have seen) to wait for newer ones only. Returns timedOut: true after timeoutSeconds (default 25, max 30); call again to keep waiting.

  • create_email_inbox

    Create an owned agent email address. Requires a Free account: one random inbox lasting activeDays (1–7, default 3). Pro allows 10 and Team 50 inboxes that remain active while subscribed; localPart selects a custom address on paid plans. Retired addresses are never reused. Then ca

  • wait_for_email

    Block until the email inbox receives a message, then return new messages with extracted one-time codes and links (verification links first). Pass after (the last message ID seen) to wait for newer ones. Returns timedOut: true after timeoutSeconds (default 25, max 30); call again

  • list_emails

    Read every message in an email inbox (up to 100): sender, subject, text, HTML, extracted codes and links, attachment names.

  • send_email

    Send from an owned socketspace.xyz inbox when operator-enabled. Free requires verified owner email and permits 30 recipient deliveries/month, 3/day (3 recipients/message); Pro 500/month, 50/day and Team 3000/month, 300/day (10/message). Supply a unique idempotencyKey; reuse it on

  • wait_for_event

    Wait once for any of 1–10 webhook, email, human approval, scheduled job or SMS sources. Each source has kind, id, optional token and after cursor. Returns events with per-source cursors, or timedOut. Waits are capped at 30 seconds and share the same per-caller wait limit. Email e

  • start_login

  • finish_login

    Wait (up to 25 seconds per call) for the human to approve the login from start_login. Returns status pending, denied, expired, or approved with the API key and MCP settings to save in your client config.

  • ask_human

    Ask your human before a risky or irreversible step (deploying, paying, deleting, emailing real people). Emails the workspace owner a link; only they can answer, signed in. Returns an id and answerUrl (show it in chat too), then call wait_for_approval. Needs an approved workspace

  • wait_for_approval

    Block until your human answers an ask_human request. Returns status answered (with answer and optional note), expired, or timedOut: true after timeoutSeconds (default 25, max 30); call again to keep waiting. Do not proceed without an answer.

  • memory_set

Common questions

Is socket.help safe?

It passed 2 of 3 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: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry yesterday.

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: Vexa, emailmd, MCP WhatsApp Cloud
