Local command
uvx crypto-sentiment-x402-mcp==0.2.0Credentials from the publisher
- CDP_API_KEY_ID — Coinbase Developer Platform API key ID (portal.cdp.coinbase.com). Used to sign x402 payments from your own wallet. Only needed for the paid tools (get_sentiment, get_sentiment_history, get_movers); the free tools work without it.
- CDP_API_KEY_SECRET — Coinbase Developer Platform API key secret, paired with CDP_API_KEY_ID. Only needed for the paid tools (get_sentiment, get_sentiment_history, get_movers); the free tools work without it.
- CDP_WALLET_NAME — Name of the CDP wallet to create/reuse for payments. Defaults to "crypto-sentiment-mcp-wallet". Must hold USDC (+ a little ETH for gas) on the configured network.
- SENTIMENT_API_URL — Base URL of the deployed sentiment API. Defaults to https://crypto-sentiment-x402.onrender.com.
- X402_NETWORK — "mainnet" (default, real USDC on Base) or "testnet" (free Base Sepolia USDC).
- SENTIMENT_PAY_TO — payTo address the paid tools expect in the 402; anything else is refused before signing. Defaults to the hosted API's wallet. Set it when SENTIMENT_API_URL points at your own deployment.
- MAX_SPEND_USD_PER_SESSION — Most this server signs for in total per run, in USD. Default 0.50; 0 turns the cap off. A paid call that would go over it is refused and not charged. Resets when the server restarts.
