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: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Other
  • You need to fill in: LAYERHOP_API_KEY

Install

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

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: LAYERHOP_API_KEY, LAYERHOP_INTEGRATOR

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

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • LAYERHOP_API_KEY secret env
    Optional LayerHop API key from dashboard.layerhop.com, for higher rate limits

Common questions

Is LayerHop safe?

It passed 1 of 1 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: LAYERHOP_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.0) reached the registry 19 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?

@layerhop/mcp

Model Context Protocol server for LayerHop: AI agents (Claude, ChatGPT, Cursor, …) can list chains and tokens, get best-price cross-chain / same-chain swap quotes with every fee spelled out, and hand the user a prefilled swap link.

The server holds no private keys and never signs or broadcasts. The user's own wallet signs.

Listed in the official MCP Registry as com.layerhop/mcp.
