Overview

AI-generated overview

Gives an assistant pay-per-call access to Base and Polygon onchain data through an x402 payment flow.

What you can do
This server exposes Base and Polygon blockchain data to an assistant, with each call paid for individually over x402 rather than through a subscription or API key. It can run as a remote HTTP endpoint or as a local npm package over stdio. The manifest does not list individual tools, so the exact queries available are not documented here.
When to use it
Worth considering when an assistant needs onchain data from Base or Polygon and a per-call payment model suits the workflow better than a fixed API plan. It is less useful if you need documented tool names or predictable flat-rate pricing before committing.
Requirements
Either a remote streamable HTTP endpoint or a local Node.js runtime for the npm package 47620-evm-mcp over stdio. No authentication, environment variables, or headers are declared, but the x402 pay-per-call model implies a funded payment method.
Before you install
Calls are billed individually through x402, so usage can spend money, and the manifest declares no credentials or spending limits. The tool list is not published, so capabilities cannot be verified in advance. Treat any payment setup as sensitive and confirm costs before running many calls.

Installation

In SourceWeft

  1. Open 47620 Base + Polygon Data API 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/xyz.47620%2Fevm-data/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
