A remote MCP server giving assistants crypto market and on-chain data — prices, candles, token details, DeFi TVL, wallet balances — paid per call in USDC on the

What you can do
List the catalog of available data calls and their prices, plus the equivalent HTTP routes, free of charge. Probe the public data sources for status and latency before spending on a paid call. Get a median USD price across venues with its spread, and recent candles for a trading pair from 1 minute to 1 day. Look up token details (name, symbol, decimals, supply, contract address, price) and overall market context such as total market cap, Bitcoin dominance and top movers. Check a DeFi protocol's total value locked with 24-hour and 7-day change, and read native or ERC-20 balances for an address.
When to use it
Useful when an assistant needs crypto prices, charts, token or protocol facts, or wallet balances without holding exchange API keys, and when per-call micro-payments are acceptable. The free catalog and source-status tools help decide whether a paid call is worth it.
Requirements
Remote endpoint at mcp.santyvv.com, or a local process from the npm package santyvv-data-mcp over stdio. No authentication, environment variables or headers are declared. Paid calls require USDC on Base settled through the x402 protocol.
Before you install
Most data tools cost money per call in USDC on Base (0.01 to 0.03 USD each), so repeated or automated use spends funds; only the catalog and source-status tools are free. Prices are aggregated medians, not a single exchange's last trade. No credentials are requested, but payment is made from a wallet on Base.

Installation

In SourceWeft

  1. Open santyvv-data — market & on-chain data 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/com.santyvv%2Ftienda/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

estado_fuentes

Upstream source status

Live probe of every public source behind the data (response, HTTP status and latency). Free: use it to decide whether a paid call is worth it, and to see where a number came from.

Takes no parameters.

precio

Market price

What an asset is worth right now, in USD, as a MEDIAN across several venues with its spread - not a single exchange's last trade. Use it to quote, to compare venues or to spot a dislocated market. Cuesta $0.02 por llamada, en USDC sobre Base (protocolo x402).

Parameterssymbols

ficha_token

Token profile and price

What a token is and what it is worth: name, symbol, decimals, supply, contract address and price per token. Use it to confirm that an address is a real contract and what it represents. Cuesta $0.03 por llamada, en USDC sobre Base (protocolo x402).

Parameterschaintokensrequired

velas

OHLC candles

Recent candles for a trading pair at the interval you ask for (1m to 1d). What you need to compute trend or volatility, or to draw a chart without an exchange API key. Cuesta $0.01 por llamada, en USDC sobre Base (protocolo x402).

Parameterslimitesymbolrequiredinterval

mercado

Market overview

The big picture: total market cap, Bitcoin dominance, 24 h change, the coins by market cap and the top movers. This is the context question, not the one about a single asset. Cuesta $0.03 por llamada, en USDC sobre Base (protocolo x402).

Parametersvslimite

tvl_protocolo

DeFi protocol TVL

How much money is deposited in a DeFi protocol (TVL in USD) with its 24 h and 7 day change. The measure of a protocol's size and health before you interact with it. Cuesta $0.01 por llamada, en USDC sobre Base (protocolo x402).

Parametersprotocol

saldo

Wallet balance

What an address holds: the native balance of the network and, if you pass a token, that ERC-20 balance with its decimals. Use it to verify a payment or a holding without opening a block explorer. Cuesta $0.03 por llamada, en USDC sobre Base (protocolo x402).
