Overview

AI-generated overview

Remote MCP server offering ten pay-per-call tools — text rewriting, writing grading, code lookups, permits, market and trade data — billed in USDC on Base via…

What you can do
  • Rewrite text into named styles and grade drafts for clarity, voice and concision
  • Look up medical billing codes (CPT/HCPCS/ICD-10, CARC/RARC) from bundled public excerpts
  • Estimate likely city permits and inspections for an address or city plus project type
  • Screen stocks or crypto for gainers, losers, volume spikes, RSI extremes and breakouts
  • Read desk trade signals and a scored paper trade log as JSON
  • Check live 402 payment probes for URLs or catalog endpoints and list recent on-chain USDC settles
When to use it
Useful when an assistant needs occasional paid, metered capabilities — writing critique or restyling, medical code lookups, permit hints, or market screening — without subscribing to a separate API. Each call is charged individually, so it suits low-volume or exploratory use rather than heavy bulk workloads.
Requirements
A remote streamable HTTP endpoint; no local install, account or API key is declared. Calls must carry an x402 payment in the request metadata, so the client needs a funded USDC wallet on Base and x402 payment support. Network access to the provider endpoint is required.
Before you install
Every tool except the free listing costs money per call (from $0.005 to $0.09 in USDC on Base); unpaid calls fail with PaymentRequired. Spending is real cryptocurrency, so set limits on the wallet used. Some tools return financial signals and paper-trade data, and permit or medical code results are heuristic lookups, not professional advice.

Installation

In SourceWeft

  1. Open Open Claw x402 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/com.openclawproductions%2Fx402-tools/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
