What is the dev.true402/mcp-server MCP server?
Pay-per-call AI + web + on-chain tools over x402 (USDC on Base): LLM, SEO, extract, token safety.
How to install dev.true402/mcp-server
Copy-paste configuration for popular MCP clients.
WALLET_PRIVATE_KEYsecretFunded Base wallet private key for x402 payment signing (optional; without it, paid tools return the 402 requirements).
SERVER_URLtrue402 API base (default https://true402.dev/api). Must be https (or localhost) — the signer refuses to send a payment over cleartext.
MAX_PAYMENT_USDCClient-side per-call spend ceiling in USDC (default 0.10). The signer refuses to auto-pay a 402 whose amount exceeds this — protects the wallet from a hostile endpoint.
