OneSource MCP server

@one-source/mcp

Unified MCP server for OneSource — 83 tools for blockchain data, live chain queries, Deepstate market data, The Standard Reserve, and REST API documentation in a single server.

What is MCP? The Model Context Protocol lets AI assistants call tools and access data sources. This server exposes both the OneSource blockchain API and its documentation as tools.

Quick Start

Claude Code

Claude Desktop / Cursor

Add to your MCP config:

{
  "mcpServers": {
    "onesource": {
      "command": "npx",
      "args": ["-y", "@one-source/mcp@latest"]
    }
  }
}

Any MCP Client (stdio)

npx -y @one-source/mcp@latest

HTTP Server (self-hosted)

npx -y @one-source/mcp@latest --http
npx -y @one-source/mcp@latest --http --port=8080

Then connect your MCP client to http://localhost:3000/ (or your --port value, e.g. 8080 in the second example above).

Health check: GET http://localhost:3000/health (substitute your port).
