Overview

AI-generated overview

A remote MCP endpoint that reports x402 settlement activity, including wash-adjusted volume and payTo checks.

What you can do
This server exposes a remote streamable HTTP endpoint at api.merona.io that reports on x402 settlement activity. According to its description, it provides wash-adjusted volume figures and payTo checks, letting an assistant look at what actually settles on x402 rather than raw reported activity. No individual tools are listed in the manifest.
When to use it
Consider it when you want an assistant to inspect x402 settlement data, for example to review wash-adjusted volume or verify payTo addresses. It is aimed at users already working with x402 payments who want settlement figures without building their own index.
Requirements
A remote MCP client that can connect to a streamable HTTP endpoint at api.merona.io. The description states it is free and needs no key or signup; no environment variables or headers are declared.
Before you install
The endpoint is third-party and remote, so queries and any data you send go to that provider. The description claims free access with no key or signup, but no tool list, terms, or data-handling details are provided, so verify what the server returns before relying on it for decisions.

Installation

In SourceWeft

  1. Open merona — x402 settlement index in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.merona%2Fsettlement-index/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

payto_check

payTo integrity check

Check whether an x402 endpoint or wallet pays out where it claims to, before your agent sends funds. Takes one wallet address or endpoint URL. Returns any catalog-vs-live payout mismatch, dated payout-rotation history, and whether the address has settled on chain. Free, no key. Use mismatch_feed instead to list every known mismatch. Records are dated facts, not accusations, and no record found is not a clearance.

Parametersqueryrequired

mismatch_feed

payTo mismatch feed

List x402 endpoints currently advertising one payout address while asking payers for another, from merona's nightly probe of the public catalog — the top 10 entries with advertised vs live addresses, full counts and as-of dates (complete feed, uncapped: merona.io/mismatches.json). Takes no arguments. Free, no key. Use payto_check instead when you already have a specific address or endpoint to check.

Takes no parameters.

clean_stats

clean settlement stats

Get wash-adjusted x402 settlement volume per chain — spend that survives removal of funded loops and self-dealing cycles, which can differ from raw transfer totals by orders of magnitude. Returns clean settlement count, clean volume in USD and an as-of date per chain. Takes no arguments. Free, no key. These are the figures published on merona.io.

Takes no parameters.

trust_score

seller trust score

Score a specific seller wallet before paying it: wash-aware m.Score with an A–F grade, component breakdown, wash flags including multi-hop cycle detection, and the snapshot SHA so the result can be re-derived independently. Requires chain and address. Free — no key or payment needed. Optional: pass payment=<base64 X-PAYMENT payload> to pay $0.001 via x402 and receive a settlement-receipted response.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
