Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`CDP_API_KEY_ID` Optional, secret	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` Optional, 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` Optional	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` Optional	Base URL of the deployed sentiment API. Defaults to https://crypto-sentiment-x402.onrender.com.
`X402_NETWORK` Optional	"mainnet" (default, real USDC on Base) or "testnet" (free Base Sepolia USDC).
`SENTIMENT_PAY_TO` Optional	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` Optional	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.
