Overview

AI-generated overview

A remote MCP server that lets an assistant verify a Base (Ethereum L2) transaction and report every USDC Transfer event in it.

What you can do
Verify a Base transaction: given a transaction hash, report each USDC Transfer event with sender, recipient, amount, block number, on-chain success and confirmation age.
When to use it
Useful when you need to confirm that a Base USDC transfer or x402 settlement actually landed on-chain before acting on it.
Requirements
A remote streamable HTTP endpoint; no account, API key or headers are declared. It reads Base's public JSON-RPC live, so network access to that endpoint is needed.
Before you install
It only reads public chain data and does not sign or send transactions. Results depend on the public JSON-RPC source and current chain state, so treat confirmation age as a snapshot.

Installation

In SourceWeft

  1. Open Tools 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/dev.workers.sebastiaan-ba3.payverify%2Ftools/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
