Overview

AI-generated overview

Gives an assistant crypto market data tools: prices, conversion, indicators, yields, gas, transaction status, balances, and ENS lookups.

What you can do
This local MCP server exposes crypto-related tools to an assistant. According to its registry description, it covers market prices, currency conversion, technical indicators, yields, gas estimates, transaction status, wallet balances, and ENS name resolution. It is described as obtaining this data via x402, a payment-oriented data access scheme.
When to use it
Worth adding when an assistant needs to answer questions about crypto markets, check a transaction or balance, estimate gas, or resolve ENS names during a session. It is a desktop-only local process, so it suits individual workstation use rather than shared or hosted deployments.
Requirements
Runs as a local process over stdio, installed from the npm package x402-crypto-mcp, so Node.js and npm are needed. The manifest declares no authentication, environment variables, or headers, but the x402 data access described may involve payment handling not detailed in the available information.
Before you install
The description mentions x402, a payment-based data access protocol, so using the server may involve spending funds or configuring payment credentials; the manifest declares no such variables, so the exact mechanism is unclear. Balance and transaction lookups may expose wallet-related information to third-party data providers. Verify what is sent and whether any payment is triggered before relying on it.

Installation

In SourceWeft

  1. Open X402 Crypto Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
