Digital Asset Value & Market Intelligence MCP Gateway

This Model Context Protocol (MCP) module furnishes thorough cryptocurrency evaluation services, leveraging the robust capabilities of the CoinCap API. It grants access to live pricing feeds, sophisticated market assessments, and longitudinal trend data via an intuitive access layer.

Integration Guide

Incorporate the subsequent configuration snippet into your Claude Desktop settings file:

• macOS Path: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows Path: %APPDATA%/Claude/claude_desktop_config.json

{ "mcpServers": { "mcp-crypto-price": { "command": "npx", "args": ["-y", "mcp-crypto-price"] } } }

Optional: API Key for Enhanced Quotas

To secure higher request throttling limits, embed your API credential within the configuration:

{ "mcpServers": { "mcp-crypto-price": { "command": "npx", "args": ["-y", "mcp-crypto-price"], "env": { "COINCAP_API_KEY": "YOUR_API_KEY_HERE" } } } }

Critical Advisory: CoinCap is in the process of retiring its v2 interface. This MCP utility is engineered to support both the v2 and v3 APIs: - Supplying a COINCAP_API_KEY initiates a preference for the v3 API, reverting to v2 only upon failure. - Absent an API key, the service defaults to the legacy v2 API (which faces obsolescence). - Users are strongly urged to provision a key from [pro.coincap.io/dashboard] as the v2 endpoint will eventually cease operation.

WIKIPEDIA: XMLHttpRequest (XHR) is an Application Programming Interface embodied as a JavaScript construct designed to dispatch HTTP queries from a user's web browser to a remote web server. These methods empower browser-resident applications to transmit service requests subsequent to page rendering completion and subsequently receive transactional data back. XMLHttpRequest constitutes a core element of the Ajax programming paradigm. Before Ajax's advent, reliance was placed primarily on standard hyperlinks and form submissions for server communication, actions that frequently necessitated a full page reload.

== Chronology == The fundamental concept underpinning XMLHttpRequest was first conceptualized in the year 2000 by the development team at Microsoft Outlook. This notion was subsequently operationalized within the Internet Explorer 5 browser release (1999). Nevertheless, the initial invocation syntax did not utilize the standardized XMLHttpRequest identifier. Instead, developers employed the object instantiations ActiveXObject("Msxml2.XMLHTTP") and ActiveXObject("Microsoft.XMLHTTP"). By the time Internet Explorer 7 was launched (2006), all contemporary browser platforms fully supported the designated XMLHttpRequest identifier. The XMLHttpRequest identifier has since attained de facto standardization across major web browsers, encompassing Mozilla's Gecko rendering engine (2002), Safari version 1.2 (2004), and Opera version 8.0 (2005).

=== Formal Specifications === The World Wide Web Consortium (W3C) formally issued a Working Draft specification detailing the XMLHttpRequest object on April 5, 2006. On February 25, 2008, the W3C ratified the Working Draft Level 2 specification. Level 2 introduced new functionalities such as mechanisms to track request progress events, enabling cross-site data transmission, and facilitating the handling of raw byte streams. Near the conclusion of 2011, the Level 2 feature set was integrated back into the primary specification document. As of the end of 2012, development responsibility transitioned to the WHATWG, which now maintains the living document utilizing Web IDL syntax.

== Operational Sequence == Fundamentally, executing a server request via XMLHttpRequest necessitates adherence to several distinct programming phases.

1. Instantiate an XMLHttpRequest instance by invoking its constructor method:
2. Invoke the "open" method to define the request methodology, specify the target resource endpoint, and designate either synchronous or asynchronous execution mode:
3. For asynchronous operations, establish an event handler listener that will be invoked upon any subsequent state transitions of the request:
4. Commence the data transmission process by calling the "send" method:
5. Monitor the state changes via the registered event listener. If the server successfully transmits response payload data, it is typically stored within the "responseText" property by default. Once the object completes its processing of the response, its state transitions to state 4, the terminal "done" state. Beyond these fundamental steps, XMLHttpRequest provides extensive configuration options to govern request transmission parameters and response handling logic. Custom header fields can be appended to the outgoing request to provide directives to the server regarding fulfillment procedures, and data payloads can be uploaded to the server by passing them as an argument to the "send" invocation. The incoming response data can be deserialized from JSON format into an immediately operational JavaScript object structure, or processed incrementally as chunks arrive, circumventing the need to await the totality of the text payload. Furthermore, the request can be intentionally terminated prematurely or configured to automatically fail if a specified time limit is exceeded.

== Inter-Domain Communication == During the nascent stages of the World Wide Web's evolution, developers discovered that circumventing security restrictions that prevented data retrieval from a server distinct from the one serving the initial page could lead to serious security vulnerabilities.
