Overview

AI-generated overview

Remote MCP endpoint offering 174 pay-per-call crypto, DeFi, on-chain and finance data tools, paid with x402 stablecoin micropayments.

What you can do
  • Query crypto, DeFi and finance data from public and official sources
  • Look up on-chain data for Bitcoin, Kaspa and Bittensor
  • Call any of 174 tools; an unpaid call returns an x402 PaymentRequired object listing payment options
  • Repeat the call with a signed payment payload in params._meta to get the data
  • Retry after a 503 from an upstream source, which is described as temporary
When to use it
Useful when an assistant needs crypto, DeFi or on-chain market data without signing up for an API key, and you are willing to pay per call in stablecoin from a wallet.
Requirements
Remote streamable HTTP endpoint; no signup or API key. A crypto wallet able to sign x402 payments in USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. Network access to the endpoint.
Before you install
Every successful tool call costs money, settled in stablecoin from your wallet; failed calls are stated not to be charged. The assistant must sign payment payloads with a wallet, so wallet access and spending limits matter. Data comes from third-party public sources and may be incomplete or delayed.

Installation

In SourceWeft

  1. Open SiteCheck Crypto & Finance 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/io.github.bck-stack%2Fsitecheck-crypto-finance/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

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
