Passed 2/3 checks · Runs on your computer · ✓ Commands checked Nov 13, 2026

First: which AI do you use?

Pick your app and the steps appear below.

Works with Claude, with some setup first

You need a Mossgate MCP key (create it on the maker’s site) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Mossgate MCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "mossgate": { "command": "npx", "args": [ "-y", "mossgate-mcp" ], "env": { "MOSSGATE_BUYER_PK": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For MOSSGATE_BUYER_PK, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Mossgate MCP tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Sign up and create a Mossgate MCP key

    Open the maker’s site, sign up and create an API key for the next step. Check the maker’s site for pricing and free plans.

    How to get a key is in the maker’s README below

Common questions

Is Mossgate MCP 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: MOSSGATE_BUYER_PK

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (0.1.1) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

mossgate-mcp

a model context protocol (mcp) stdio server that exposes two live paid apis to any mcp-enabled agent:

  • mossgate trust (https://api.mossgate.dev) token and wallet risk checks
  • rue render (https://rue.mossgate.dev) url/html to pdf/png/jpeg

payment is x402 v2, usdc on base. the operator who runs this server funds a wallet, and every tool call spends a little usdc from it. the wallet signs an eip-3009 authorization gaslessly, so it needs only usdc, no eth for gas.

tools

  • token_verdict(address, chain=base) quick risk verdict for a token contract
  • wallet_profile(address, chain=base) behavioural risk profile for a wallet
  • token_report(address, chain=base) full token report
  • render(url|html, format=pdf|png|jpeg) render a page, returns a base64 file

install

cd mcp-server

npm install

node 18+ is required.

fund the wallet

  1. create or reuse an evm wallet (any tool that gives a 0x private key).
  2. send it usdc on base (contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913). a few dollars covers many calls. no eth is needed, gas is sponsored by the facilitator.
  3. export the private key as an env var (never commit it):
export MOSSGATE_BUYER_PK=0xyourprivatekey

optional overrides: MOSSGATE_RPC (base rpc url), MOSSGATE_TRUST_URL, MOSSGATE_RENDER_URL.

run standalone

MOSSGATE_BUYER_PK=0x... node index.js

the server speaks mcp over stdio. it is meant to be launched by an mcp client, not used by hand.

claude desktop / mcp client config

add this to your mcp client config (for claude desktop: ~/.config/Claude/claude_desktop_config.json on linux, or ~/Library/Application Support/Claude/claude_desktop_config.json on macos):

{

"mcpServers": { "mossgate": { "command": "node", "args": ["/absolute/path/to/products/mcp-server/index.js"], "env": { "MOSSGATE_BUYER_PK": "0xyourprivatekey" } } } }

restart the client. the four tools appear and each call is paid automatically from the funded wallet.

verify it starts (no paid calls)

this lists the tools over stdio without touching the apis or spending anything:

printf '%s\n' \

'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"probe","version":"0"}}}' \ '{"jsonrpc":"2.0","method":"notifications/initialized"}' \ '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' \ | node index.js

run without cloning

this package is on npm, so agents and clients can run it via npx with no clone or install. set the command to npx and args to ["-y", "mossgate-mcp"] in the client config:

{

"mcpServers": { "mossgate": { "command": "npx", "args": ["-y", "mossgate-mcp"], "env": { "MOSSGATE_BUYER_PK": "0xyourprivatekey" } } } }
