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 structured payment_required object with the exact x402 requirements (price, payTo, asset, nonce).
Sign the exact-scheme EIP-712 USDC authorization with your wallet (@x402/fetch for TS, x402 for Python handle this), then call the tool again with the base64 token in the payment_signature argument.

Cheapest way to test the full flow end-to-end: get_delay_risk_demo ($0.002).
