Overview

Description from the maker (original English)

Send push to Android, iOS and the web, and ask a trusted phone to approve a login, from your agent.

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: Developer tools
  • 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 signops https://api.signops.dev/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": {
    "signops": {
      "url": "https://api.signops.dev/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": {
    "signops": {
      "type": "http",
      "url": "https://api.signops.dev/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 required HTTP header
    Bearer and your SignOps secret key. Use a test key (sk_test_) while building.

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 7, 2026. The maker wrote them, not us; we show them as plain text.

  • send_push

    Send a push notification to one user (user_id), a list (user_ids, up to 1,000), a topic, or everyone (all: true). Give exactly one target. A push to one user, sent now, answers with its result at once; others answer with status sending or scheduled. With a test key (sk_test_) onl

  • get_push

    One push by id: status, devices, sent and failed, per platform.

  • list_pushes

    Pushes, newest first. On the Free plan only pushes still to go are listed (no delivery logs).

  • cancel_push

    Cancel a push that is scheduled and has not started sending.

  • register_device

    Store a device's push token under your user id. Android and iOS tokens come from the Firebase or Apple SDK; for web, token is the PushSubscription as JSON.

  • list_devices

    The devices registered for one user id, newest first, with platform and whether each is trusted for approvals.

  • remove_device

    Remove one device by id; it gets no more pushes.

  • list_topics

    Topics with how many users each has.

  • subscribe_topic

    Add a user to a topic. The topic exists once it has a user.

  • unsubscribe_topic

    Take a user off a topic.

  • list_templates

    Saved push templates with their fields.

  • get_template

    One template by name.

  • save_template

    Create or replace a template. Put {{field}} where a value goes, or {{field|default}} for one with a fallback.

  • delete_template

    Delete a template by name. Pushes already made from it are not changed.

  • create_approval

    Send an approval request to the user's trusted phone, with number matching. The user must have a phone enrolled through the SignOps SDK.

  • get_approval

    An approval request's status: pending, approved, denied, expired or cancelled.

  • cancel_approval

    Cancel a pending approval request.

  • list_passkeys

    The passkeys registered for one user id.

  • get_authenticator

    Whether a user has an authenticator app (TOTP) confirmed, when it was last used, backup codes left, and whether wrong codes have locked them.

  • remove_authenticator

    Remove a user's authenticator app and backup codes, for a lost phone. They can enrol again.

  • unlock_user

    Clear the lock that five wrong codes in 15 minutes put on a user, and their count of wrong codes.

  • export_user

    Everything SignOps holds on one user id as JSON: devices (tokens shortened), topics, passkeys, authenticator status, approvals of the last 90 days, consent history and pushes sent to them.

  • get_consent

    The latest consent answer per purpose for one user, like marketing_push, and the history.

Common questions

Is SignOps 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 13 days ago.

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: GitHub, Desktop Commander, Cloudflare MCP
