47620 Multichain Data API — onchain, crypto, utilities, x402 stats MCP server

47620 Data — MCP server (multichain)

Give any MCP-capable AI agent (Claude, Cursor, Windsurf, OpenClaw, …) native access to 47620 pay-per-call on-chain data, settled over x402 (HTTP 402) in USDC — non-custodial, no signup, no API key.

Multichain (v1.1+). The remote server 47620-multichain serves Solana, Base and Polygon

from one endpoint. Every neutral tool takes an explicit chain param (solana | base | polygon)

and resolves an explicit per-chain path, e.g.

health → /x/solana/health · /x/base-fac/health · /x/polygon-fac/health.

The chain you pay on is independent of the chain you query (pay USDC on any of the three).

Legacy solana_* tool names keep working as aliases.

Remote (streamable HTTP): https://47620.xyz/mcp/multichain (also /mcp).

Multichain tools (v1.1)

Solana tools (native)

Give any MCP-capable AI agent (Claude, Cursor, Windsurf, OpenClaw, …) native access to 47620 pay-per-call Solana data, settled over x402 (HTTP 402) in USDC on Solana — non-custodial, no signup, no API key.

Tools

Each tool call is an x402 paid request: the server gets a 402, pays USDC to the merchant wallet on Solana, and retries with the payment header. Funds go directly to the seller's wallet; a 1% platform fee is a second on-chain transfer.

Install

From npm (published as 47620-solana-mcp):

npx -y 47620-solana-mcp

Or clone and run:

git clone https://github.com/fito311/solana-data-mcp
cd solana-data-mcp && npm install && node src/index.js

Configure (Claude Desktop / Cursor / any MCP client)
