Common questions

Is Vibe Springs safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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](https://www.x402.org) 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).

Network: Base mainnet (eip155:8453)
Asset: USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)
