What is A Model Context Protocol (MCP) server that provides JSON-RPC functionality through OpenRPC.?

OpenRPC MCP Server is a Model Context Protocol (MCP) server that provides JSON-RPC functionality through OpenRPC. It includes tools for calling arbitrary JSON-RPC methods and discovering available methods. The server can be installed and configured for use with Claude Desktop, and debugging tools are available through the MCP Inspector.

Features# Tools

  • rpc_call - Call arbitrary JSON-RPC methods
  • Specify server URL, method name, and parameters
  • Returns JSON-formatted results
  • rpc_discover - Discover available JSON-RPC methods
  • Uses OpenRPC's rpc.discover specification
  • Lists all methods on a given server

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "openrpc": {
      "command": "npx",
      "args": ["-y", "openrpc-mcp-server"]
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
