Coinmarket MCP Server: Empowering AI Applications through Universal Data Access

Overview: What is Coinmarket MCP Server?

The Coinmarket MCP Server provides AI applications like Claude Desktop, Continue, and Cursor with seamless access to real-time cryptocurrency data and tools via the Model Context Protocol (MCP). By integrating this server, these applications can utilize a standardized protocol to fetch current market listings, generate currency quotes, and more. This integration enhances their utility and functionality, making them more powerful tools for users engaged in financial and technical analysis.

🔧 Core Features & MCP Capabilities

The Coinmarket MCP Server offers several core capabilities, including:

• Custom URI Scheme: Enables deep linking to specific notes through coinmarket:// URIs.
• Resource Management: Each note resource holds unique identifiers such as name, description, and content type; specifically text/plain.

These features are made possible through a robust implementation of the MCP protocol. The server ensures that AI applications can seamlessly interact with Coinmarket's API endpoints using these standardized interfaces.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Coinmarket MCP Server is designed to support efficient data retrieval and tool invocation within the broader MCP ecosystem. It leverages modern web technologies such as Node.js, ensuring compatibility across various client platforms like macOS and Windows. Environmental variables like COINMARKET_API_KEY are crucial for securing API interactions.

🚀 Getting Started with Installation

To set up the Coinmarket MCP Server on your system, follow these steps:

For Claude Desktop:

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

Edit your configuration file to include an entry for the Coinmarket MCP Server. Here is a sample configuration snippet:

{
  "mcpServers": {
    "coinmarket_service": {
      "command": "uv",
      "args": ["--directory", "/Users/anjor/repos/anjor/coinmarket_service", "run", "coinmarket_service"],
      "env": {"COINMARKET_API_KEY": ""}
    }
  }
}

💡 Key Use Cases in AI Workflows

Real-time Market Analysis

AI applications like Claude Desktop can integrate live market data provided by the Coinmarket MCP Server. For instance, a user could request a summary of current token prices and receive real-time quotes based on user-defined query parameters.

get_quotes("BTC")

This command would trigger the server to fetch the latest Bitcoin (BTC) quote from Coinmarket's API.

Custom Note Creation

Users can create personalized notes with names, descriptions, and plain text content. These notes can be accessed via specific coinmarket:// URIs, enabling quick retrieval by AI applications. For example:

create_note("Bitcoin_History", "Detailed history of the most valuable cryptocurrency", "https://www.bitcoin.org/bitcoin.pdf")

🔌 Integration with MCP Clients

The Coinmarket MCP Server supports integration with various MCP clients, including:

• Claude Desktop: Fully supported.
• Continue: Fully supported.
• Cursor: Limited to tool invocation.

However, prompt generation and resource creation are not currently compatible due to the limitations of Cursor's API protocol.

📊 Performance & Compatibility Matrix

The following table outlines compatibility details between MCP clients and server resources/tools:

MCP Client	Resource	Tool	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

🛠️ Advanced Configuration & Security

Ensure that sensitive information like API keys are stored securely in environment variables. The example configuration snippet above demonstrates how to specify these settings within the server's configuration file.

"env": {"COINMARKET_API_KEY": ""} 

For enhanced security, use secure methods like HTTPS to protect data exchanges between clients and servers.
