Overview

AI-generated overview

Hosted MCP server offering pay-per-call weather, finance, on-chain and market data tools, settled in USDC on Base via x402.

What you can do
Search the catalog and check service health for free, including upstream probes and paid-call reliability stats. Retrieve weather forecasts, historical weather, and weather-and-soil delay risk scores. Get fiat exchange rates, currency conversion, crypto prices, crypto news with sentiment, and DeFi yield scans. Profile wallets, run on-chain risk reports, and check gas prices on Base, Ethereum, Arbitrum and Optimism. Pull composite snapshots combining crypto, FX, gas and yields, or a travel brief with forecast, air quality, holidays and FX. Register and check standing watch conditions on prices, gas, weather, wallets or endpoints, and audit x402 merchant listings and Bazaar trends.
When to use it
Useful when an assistant needs current weather, FX, crypto or on-chain data without managing API keys, and the caller is willing to pay small per-call USDC fees from its own wallet. Also aimed at x402 merchants who want listing health, competitor and visibility audits.
Requirements
A remote Streamable HTTP endpoint; nothing to install. No account or API key is needed to connect, and the free tools work immediately. Paid tools require a wallet that can sign EIP-712 USDC authorizations on Base mainnet, passed as the payment_signature argument, typically via an x402 client library.
Before you install
Most tools cost real money in USDC on Base mainnet, from about $0.001 to $0.75 per call, charged per invocation. The agent's own wallet signs payment authorizations, so spending limits and key handling matter. Watch tools store conditions and send notifications, and audit tools send third-party endpoint details to the provider.

Installation

In SourceWeft

  1. Open Vibe Springs in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/net.vibesprings%2Fx402-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

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.

Connect

Claude Code

bash
claude mcp add -t http vibesprings https://vibesprings.net/mcp

Paying (x402 over MCP)

Paid tools implement a two-step handshake so the agent stays in control of its wallet:

  1. Call the tool without payment_signature → the response is a structured payment_required object with the exact x402 requirements (price, payTo, asset, nonce).
  2. 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).

Parametersurlrequiredpayment_signature

get_listing_intel

Audit your own x402 listings against the live Bazaar catalogue.

Parameterstagdomainpay_topayment_signature

get_market_history

The x402 Bazaar as a time series, reconstructed from our own daily snapshots. Coinbase's discovery API returns only the catalogue as it is right now - it has no archive. This returns per-day ecosystem GMV, merchant and listing counts, price-band distribution and median/P90 pricing; per-merchant lifecycle with first-seen, last-seen and departure; every observed price change with date and magnitude; and the biggest movers ranked by change in unique paying wallets rather than call count, because call volume is trivially inflated by a merchant calling its own endpoint. The free current-snapshot view is at /state-of-x402. [PAID: $25 USDC per call via x402 on Base. First call without payment_signature returns the payment requirements.]

Parametersdaysmerchantpayment_signature

check_listing_health
