Overview

AI-generated overview

Remote pay-per-call MCP server offering crypto, sanctions, company, domain and utility tools billed in USDC on Base via x402.

What you can do
  • List the paid services on the server, with prices, HTTP paths and OpenAPI documents
  • Run deterministic agent utilities: unit and currency conversion, timezone and date maths, cron expansion, entity extraction, format and JSON Schema validation
  • Read Base and Ethereum chain data: gas, blocks, balances, token metadata, transactions, nonces, contract code and token safety verdicts
  • Screen names, wallet addresses and batches against OFAC, OFSI and EU sanctions lists, and manage a watchlist
  • Check Base token due diligence, reference prices and exit costs, and compare OpenAPI specs for breaking changes
  • Build company dossiers and SEC EDGAR financial briefs, check domain DNS, email auth, WHOIS and…
When to use it
Useful when an agent needs small, exact, on-demand answers it cannot compute locally: chain reads, sanctions screening, company filings, domain trust checks or page-change monitoring, with per-call payment instead of a subscription.
Requirements
A remote streamable HTTP endpoint; no local package or runtime. No account or API key is declared. Each paid call needs an x402 payment payload in params._meta with USDC on Base (eip155:8453), so a funded wallet and x402-capable client are required. Network access to the endpoint.
Before you install
Most tools cost money per call (typically $0.01–$0.02 in USDC on Base) and are paid by signing an x402 payment payload, so a wallet key is involved and spending can accumulate across repeated calls. Tools that write a watchlist change stored data. Queries about names, addresses, domains and companies are sent to a third-party service.

Installation

In SourceWeft

  1. Open Automaton 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/uk.firstmention.api%2Fautomaton/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
