Overview

Description from the maker (original English)

Verify XRP payments on Flare FDC. Agents subscribe or pay per attestation via x402 on XRPL.

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.

Install

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

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 4 things (tools) verify_xrp_payment, get_attestation_status, lookup_attestation_by_tx, get_server_info
  • The registry lists no key to fill in.

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.

  • verify_xrp_payment

    Submit a native XRP Payment hash for FDC attestation on Flare. Only Payments from the last 14 days can be proven. Subscription API keys inside quota are not charged extra (Paid: 20 mainnet attestations per billing period; Pro: 100). Failed prepares do not consume quota. Without a

  • get_attestation_status

    Get the current status of an attestation by its UUID. Unauthenticated callers receive the public receipt subset. The owning API key receives the full proof.

  • lookup_attestation_by_tx

    Look up an attestation by its original XRP transaction hash. Unauthenticated callers receive the public receipt subset. The owning API key receives the full proof.

  • get_server_info

    Get XRPLink server information, network details, contract addresses, and white-label branding.

Common questions

Is XRPLink safe?

It passed 3 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?

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 (0.3.0) reached the registry 12 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: Spec Driven Development, Remote Desktop Commander, NexusWindows

Architecture

┌───────────────────────┐

│ User dApp │ (Flare EVM) │ (PaymentVerifier.sol)│ └────────┬──────────────┘ │ verifyXRPPayment(proof) ▼ ┌───────────────────────┐ │ FdcVerification │ (enshrined FDC protocol contract) │ (via ContractRegistry)│ └────────┬──────────────┘ │ ┌────┴────┐ │ DA Layer│──── Proof + response └────┬────┘ │ ┌────┴────┐ │ Verifier│──── ABI-encoded request with MIC └────┬────┘ │ XRP Testnet / Mainnet

Lookback: Flare's XRPPayment attestation (IXRPPayment lutlimit 0x127500) can only prove native XRP Payments from the last 14 days. Older hashes still exist on XRPL, but the hosted verifier returns INVALID: TRANSACTION DOES NOT EXIST. XRPLink preflights the ledger and returns TX_TOO_OLD instead of a misleading FdcHub error. Failed prepares do not consume monthly quota.

Key data flow:

  1. XRP tx happens on XRP Ledger
  2. Verifier API fetches tx details, computes MIC, returns ABI-encoded request
  3. Request submitted to FdcHub on Flare with FLR fee
  4. FDC providers independently verify the XRP tx, reach consensus (90s round)
  5. Merkle root stored onchain via Relay contract
  6. DA Layer serves attestation response + Merkle proof
  7. Smart contract verifies proof against onchain Merkle root via FdcVerification
