Vibe Springs — Hosted MCP Server
Pay-per-use data & intelligence tools for AI agents. No API keys, no accounts — paid tools settle per call in USDC on Base via the x402 protocol.
This repository is the public manifest for the hosted Vibe Springs MCP server. The server runs at
https://vibesprings.net/mcp— there is nothing to install or build. Connect directly over Streamable HTTP.
- 🌐 Endpoint:
https://vibesprings.net/mcp(Streamable HTTP, stateless) - 🧰 22 tools — 2 free, 20 pay-per-call
- 💸 Payment: x402 on Base mainnet (USDC), signed per call by the agent's own wallet

Paying (x402 over MCP)
Paid tools implement a two-step handshake so the agent stays in control of its wallet:
- Call the tool without
payment_signature→ the response is a structuredpayment_requiredobject with the exact x402 requirements (price,payTo, asset, nonce). - Sign the exact-scheme EIP-712 USDC authorization with your wallet
(
@x402/fetchfor TS,x402for Python handle this), then call the tool again with the base64 token in thepayment_signatureargument.
Cheapest way to test the full flow end-to-end: get_delay_risk_demo ($0.002).
