Overview

Description from the maker (original English)

8 CIPHER tools — Solana scan, breach check, Jito, FRED, Drift, repo health, more. x402-paid on Base.

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: Clinics & health

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.
  • The registry lists no key to fill in.

Common questions

Is CIPHER x402 — Paid Solana & Crypto Tools 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?

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 (0.1.0) reached the registry 7 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?

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.

cipher-x402-mcp

An MCP server that exposes 8 Solana / crypto / macro tools to any MCP-aware client (Claude Desktop, Cursor, Cline, Continue, etc.). Seven of the tools are gated behind the x402 payment protocol — agents auto-pay in USDC on Base, $0.005 – $0.25 per tool call. One tool is free (educational).

The server is a forward-only relay: when an agent calls a paid tool

without an X-PAYMENT header, we surface the upstream HTTP 402 +

accept-list verbatim so the agent's own wallet signs the payment. We

never custody caller funds.

Free + MIT-licensed. Fork it, ship your own, no strings.


Hosted Plans (MCPize)

Prefer not to self-host? A managed listing is live on MCPize with gateway proxying, rate limiting, API-key auth, and consolidated billing:

Base network, USDC asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. The current x402 payout recipient is exposed via the root / JSON manifest at runtime — agents discover it automatically, you don't configure it by hand.

Install (Claude Desktop)

Add this to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{

"mcpServers": { "cipher-x402": { "command": "npx", "args": ["-y", "cipher-x402-mcp"] } } }

Restart Claude Desktop. The 8 tools show up in the tool tray.

Install (Cursor / Cline / Continue)

Any MCP-over-stdio client works the same way — the launcher is npx -y cipher-x402-mcp.

Install (Smithery)

npx -y @smithery/cli install cipher-x402-mcp --client claude

Remote HTTP transport

Deployed at https://cipher-x402-mcp.vercel.app/mcp (streamable HTTP). Probe the manifest at the root URL.

How payment works

  1. Agent calls (e.g.) solana_wallet_scan({ "address": "..." }) without a payment.
  2. Server returns a structured result starting with HTTP 402 Payment Required — upstream returned an x402 accept-list. followed by the JSON accept-list (price, network, payTo, asset, etc.).
  3. Agent's wallet signs an EIP-3009 authorization for the advertised maxAmountRequired.
  4. Agent re-invokes the same tool with { "address": "...", "_payment": " " }.
  5. Server forwards the X-PAYMENT header upstream, upstream's facilitator verifies + settles on Base, and the content is returned to the agent.

The server itself is stateless — no API keys, no user session, no funds.


🏃 Run it yourself

Prerequisites
  • Node.js 20+ (22 recommended)
  • npm 10+
  • A Vercel account (free tier) if you want to deploy the HTTP transport
  • No API keys required for local stdio use — the server is a pass-through to public upstream endpoints
Clone + build
git clone https://github.com/cryptomotifs/cipher-x402-mcp

cd cipher-x402-mcp npm install npm run build npm run smoke # tool-registry smoke test npm start # stdio transport npm run start:http # HTTP transport on :8080

Configure your own upstream endpoints (optional)

All upstream base URLs are overridable via env — useful if you fork the upstream endpoints to your own Vercel project and want the MCP server to route to them:

CIPHER_SCAN_API_URL=https://your-scan.example.com \

CIPHER_PWNED_URL=https://your-pwned.example.com \ CIPHER_JITO_TIP_URL=https://your-jito.example.com \ CIPHER_REPO_HEALTH_URL=https://your-repo-health.example.com \ CIPHER_FRED_URL=https://your-fred.example.com \ CIPHER_DRIFT_URL=https://your-drift.example.com \ CIPHER_X402_URL=https://your-x402.example.com \ npx cipher-x402-mcp

Deploy to Vercel
vercel link

vercel --prod

The /mcp route serves MCP JSON-RPC messages; / serves a lightweight JSON manifest used by registries.
