Overview

Description from the maker (original English)

320 AI models + 2,720 pay-per-call APIs. x402 USDC on Base or Solana, no API key.

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

Common questions

Is JarvisClaw — AI Gateway & API Marketplace 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (1.1.0) 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. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

JarvisClaw MCP Server

283 AI models and 2,720 pay-per-call APIs through one MCP server. Settles in USDC on Base or Solana over x402 — no account, no API key, no subscription.

Three ways to reach a service:

  • Models — 283 of them (GPT-5, Claude Opus 5, Gemini 3, DeepSeek) behind one OpenAI-compatible chat tool, or auto to let the router pick.
  • API marketplace — 2,720 individually priced endpoints across 40 categories (search, blockchain, code, DNS, image, document, OCR, email, geo, TTS…), of which 411 are curated. Search it, read the price, then call it.
  • AIP intents — 13 intent types. Say what you need (web_search, image_generation, translation…) and AIP resolves it to a provider, so the caller never has to know the URL layout.

Counts move as the catalogue changes; list_models, search_apis and aip_list_intents are the live answer.

Quick start

Local wallet signing (recommended for x402)

Run this package. It presents itself to your client as a normal stdio MCP server, forwards every request to the gateway, and when a call needs paying it signs the x402 payment on your machine and retries. Your private key is never transmitted — only the signed payment payload is.

JARVISCLAW_WALLET_KEY=0xyourkey npx jarvisclaw-mcp

Claude Desktop / Cursor, Base wallet:

{

"mcpServers": { "jarvisclaw": { "command": "npx", "args": ["-y", "jarvisclaw-mcp"], "env": { "JARVISCLAW_WALLET_KEY": "0xYOUR_BASE_PRIVATE_KEY", "JARVISCLAW_CHAIN": "base" } } } }

Solana wallet:

{

"mcpServers": { "jarvisclaw": { "command": "npx", "args": ["-y", "jarvisclaw-mcp"], "env": { "JARVISCLAW_WALLET_KEY": "YOUR_SOLANA_BS58_SECRET_KEY", "JARVISCLAW_CHAIN": "solana" } } } }

Direct URL (no local process)

For Claude Code, Cursor, or any client with Streamable HTTP transport. One less hop, but there is no wallet in this path: free tools work, and paid tools need a pre-paid API key, because nothing here can sign a payment.

{

"mcpServers": { "jarvisclaw": { "type": "url", "url": "https://api.jarvisclaw.ai/mcp", "headers": { "Authorization": "Bearer sk-your-api-key" } } } }

Without the header the same URL still lists the catalogue for free; paid tools answer with an x402 quote that you would have to sign yourself.

Environment variables

Free tools answer without credentials, so you can list the catalogue before deciding to pay for anything. Protocol methods (initialize, tools/list, resources/list) are free too.

Paying

MethodHeaderWhen
x402 USDCPAYMENT-SIGNATURENo account. Wallet settles on Base or Solana.
API keyAuthorization: Bearer sk-…Pre-paid account.

A paid tool called without either does not fail — it answers with an x402 quote:

tools/call → 402 with payment terms (amount, asset, payTo, network)

→ this proxy signs a USDC authorization locally → retry with PAYMENT-SIGNATURE → result

With JARVISCLAW_WALLET_KEY set, all three steps happen inside this process and your client just sees the result. Without it, the quote is passed through to your client unanswered.

Both chains are live, which most x402 sellers cannot say: settle wherever the agent already holds USDC rather than bridging to reach one gateway. Every paid response carries an EIP-712 signed settlement receipt that a third party can verify offline — recompute the hashes, recover the signer, check the tx on-chain — without trusting us.

Security

  • The wallet key is read from the environment and used only to sign payment authorizations locally. It is never sent to the gateway or anywhere else.
  • A safety cap rejects any single payment above 100 USDC, on both chains.
  • The USDC contract address, mint, chain IDs and decimals are pinned as protocol constants, not configuration — a server cannot talk this proxy into signing a transfer of some other asset.
Dependency advisories

npm audit reports 3 moderate advisories reachable through @solana/web3.js (itself, plus jayson and uuid). 1.98.4 is the latest release and is inside the flagged range, so there is no version to move to; npm's suggested "fix" is a downgrade to 0.0.3, which is not a real option. Tracked, not resolved.

This applies to Base-only users too: @solana/web3.js is a static import in the entry module, so it loads whatever JARVISCLAW_CHAIN is set to (measured: 6 module resolutions on the Base path). Only the signer *object* is constructed lazily.
