Openrpc Mcp Server

What is OpenRPC MPC Server?

OpenRPC MPC Server is a Model Context Protocol (MCP) server that provides JSON-RPC functionality through OpenRPC. It allows developers to create and manage RPC (Remote Procedure Call) services in a structured and standardized way. This server is particularly useful for applications that require a robust and flexible communication protocol between clients and servers.

Features of OpenRPC MPC Server

JSON-RPC Support: The server implements the JSON-RPC protocol, enabling easy communication between clients and servers using JSON format.
Model Context Protocol: It adheres to the Model Context Protocol, which allows for better organization and management of RPC methods and their contexts.
Public Repository: The OpenRPC MPC Server is available as a public repository, allowing developers to contribute, fork, and star the project.
Easy Integration: It can be easily integrated into existing applications, making it a versatile choice for developers looking to implement RPC functionality.
Apache-2.0 License: The project is licensed under the Apache-2.0 license, allowing for both personal and commercial use.

Frequently Asked Questions

What is JSON-RPC?

JSON-RPC is a remote procedure call (RPC) protocol encoded in JSON. It allows for notifications and multiple calls to be sent to the server, which can respond with results or errors.

How does OpenRPC differ from traditional RPC?

OpenRPC provides a standardized way to describe and document RPC APIs, making it easier for developers to understand and use them. It also supports features like versioning and context management.

Can I use OpenRPC MPC Server in production?

Yes, OpenRPC MPC Server is designed to be robust and can be used in production environments. However, it is always recommended to thoroughly test any software before deploying it in a live setting.

Is there support for different programming languages?

While the OpenRPC MPC Server is primarily implemented in JavaScript, the JSON-RPC protocol is language-agnostic, meaning you can interact with it from any programming language that supports HTTP and JSON.

How can I report issues or request features?

You can report issues or request features by opening an issue in the GitHub repository. The maintainers will review your request and respond accordingly.

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.
