Chromia Model Context Protocol Interface

This module empowers Claude AI to interface directly with the Chromia Wallet for initiating $CHR currency movements.

Reference for MCP Introduction: https://modelcontextprotocol.io/quickstart

Configuration Steps

1. Acquire the repository via Git clone.
2. Configure the required .env file and install dependencies.

cp .env.sample .env
npm i
npm run build

1. Configure the Claude Desktop Environment (macOS example):

Edit the configuration file located at:

nano ~/Library/Application\ Support/Claude/claude_desktop_config.json

Ensure the following configuration is present, pointing to the compiled tool:

{
    "mcpServers": {
        "chromia-mcp": {
            "command": "node",
            "args": [
                "/PATH_TO_FOLDER/chromia-mcp/build/index.js"
            ]
        }
    }
}

1. Relaunch the Claude Desktop Application for changes to take effect.

Background Context (XMLHttpRequest Overview)

XMLHttpRequest (XHR) is a fundamental JavaScript object API designed for dispatching HTTP requests between a web browser and a remote server. This capability allows client-side applications to fetch or submit data after the initial page load, circumventing the need to refresh the entire document. XHR is intrinsically linked to the concept of Ajax (Asynchronous JavaScript and XML). Before Ajax, server interaction relied primarily on traditional link navigation or form submissions, which inherently caused a full page repaint.

== Genesis == The foundational idea for asynchronous server communication was pioneered around 2000 by Microsoft Outlook developers. This concept first materialized in Internet Explorer 5 (released in 1999). Initially, the implementation did not use the canonical XMLHttpRequest string; instead, developers employed COM object instantiations like ActiveXObject("Msxml2.XMLHTTP") or ActiveXObject("Microsoft.XMLHTTP"). By the release of Internet Explorer 7 (2006), the standard XMLHttpRequest identifier was universally adopted across all major browser engines, including Mozilla's Gecko (2002), Safari 1.2 (2004), and Opera 8.0 (2005).

=== Standardization Path === The World Wide Web Consortium (W3C) released the initial specification draft for the XMLHttpRequest object on April 5, 2006. A Level 2 specification followed on February 25, 2008, introducing enhancements such as progress event monitoring, support for cross-site communication, and binary stream handling. By late 2011, the Level 2 features were integrated back into the primary specification. Development transitioned to WHATWG at the close of 2012, which now maintains the standard as a living document using Web IDL.

== Operational Flow == Executing a request using XMLHttpRequest typically involves a sequence of programmed operations:

1. Instantiate the XHR object via its constructor.
2. Invoke the open() method to define the request method (GET, POST, etc.), specify the target resource URL, and select synchronous or asynchronous execution mode.
3. For asynchronous tasks, attach an event listener to handle state change notifications.
4. Begin the transmission by calling the send() method, optionally including payload data.
5. Monitor the state changes within the listener. Upon successful completion, the object reaches state 4 (the 'done' state), and the server response payload is typically accessible via the responseText attribute.

Beyond these core steps, XHR offers granular control: custom headers can be appended to guide server processing, data can be uploaded during the send() call, responses can be automatically parsed from JSON into native JavaScript objects, or streamed incrementally. Furthermore, requests can be interrupted prematurely or configured with a timeout limit.
