VerifiedStreamable HTTPWeb executableFinanceDeveloper Tools

Overview

AI-generated overview

MCP server for the Coinbase HTTP 402 payment protocol, letting an assistant build payment challenges, verify on-chain settlement and list supported chains.

What you can do
  • List the blockchain networks the server supports for payment settlement
  • Build HTTP 402 payment challenges that an agent can present for a paid call
  • Verify that a payment has been settled on-chain
  • Wrap per-call, pay-per-use access for agents around the x402 protocol
When to use it
Useful when building or testing agent workflows that charge per API call through the HTTP 402 / x402 protocol and need challenge creation and on-chain payment verification.
Requirements
Runs either as a remote endpoint at api.meok.ai or as a local Python process installed from PyPI (pip or uvx, stdio transport). No environment variables or headers are declared.
Before you install
The server is about payments and on-chain settlement, so calls may involve real funds or wallet interactions; review what it signs or verifies before use. The README also pushes paid tiers and Stripe purchase links, which are unrelated to the tool's function.

Installation

In SourceWeft

  1. Open Agent X402 Paywall Mcp 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.github.CSOAI-ORG%2Fagent-x402-paywall-mcp/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

Other MCP clients

Add this to your client's mcpServers config.
