Overview

AI-generated overview

Maxwell Directory lets an assistant browse, price and buy data products — ski travel, company, legal, safety and market records — paying per call in USDC via…

What you can do
  • Search and price products: list products, get an exact quote, read charging terms, send feedback
  • Preview data free: fixed sample answers, ski coverage, trip maps, food coverage, model rates
  • Buy ski travel data: lift prices, quotes, resort profiles, operator and inventory details, trip steps and bundles
  • Buy public records: company registers and SEC filings, legislation, open data, sanctions, openFDA, CVEs, patents, court opinions
  • Buy finance and crypto data: macro series, exchange rates, crypto quotes, token safety, domain registration, npm package facts
  • Run chat completions and diagnose x402 payments, or buy any product by id
When to use it
Useful when an assistant needs sourced third-party records (ski travel, company, legal, safety, finance) and the user is willing to pay small per-call fees in USDC. Free tools let you inspect coverage and sample answers before committing to any purchase.
Requirements
Runs as a remote endpoint or as the npm package @maxwellintl/x402-mcp over stdio. Paying requires a wallet: a file with a Base (EVM) private key via MAXWELL_WALLET_KEY_FILE or a Solana secret key file via MAXWELL_SOLANA_KEY_FILE. Budget caps are set with MAXWELL_DAILY_BUDGET_USD and MAXWELL_MAX_PER_CALL_USD. No account or API key is declared.
Before you install
Paid tools spend real USDC from the configured wallet; the wallet key files hold private keys, so protect them and keep the budget caps low. Some products are sold blind (insider tips) or charge even for negative answers (domain registration). Results are third-party data and should not be treated as instructions. Free tools make no payment.

Installation

In SourceWeft

  1. Open Maxwell Directory (x402 + 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/ai.maxwellinternational%2Fdata/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.
