Clojars MCP Server: Enhancing AI Application Integration through Model Context Protocol (MCP)

---

Overview: What is Clojars MCP Server?

The Clojars MCP Server is a specialized model context protocol server designed to provide tools for fetching dependency information from Clojars, the central repository for the Clojure programming language. This server enables AI applications like Claude Desktop and other MCP clients to seamlessly integrate with external data sources such as artifact repositories to enhance their capabilities.

🔧 Core Features & MCP Capabilities

The Clojars MCP Server offers two core tools that are essential for managing dependencies in Clojars:

1. get_clojars_latest_version

   • Description: Retrieve the latest version of a specified Clojars dependency.
   • Input Schema:

     {
       "name": "get_clojars_latest_version",
       "description": "Get the latest version of a Clojars dependency (Maven artifact)",
       "inputSchema": {
         "type": "object",
         "properties": {
           "dependency": {
             "type": "string",
             "description": "Clojars dependency name in format 'group/artifact' (e.g., 'metosin/reitit')"
           }
         },
         "required": ["dependency"]
       }
     }
     

2. check_clojars_version_exists

   • Description: Verify the existence of a specific version of a Clojars dependency.
   • Input Schema:

     {
       "name": "check_clojars_version_exists",
       "description": "Check if a specific version of a Clojars dependency exists",
       "inputSchema": {
         "type": "object",
         "properties": {
           "dependency": {
             "type": "string",
             "description": "Clojars dependency name in format 'group/artifact' (e.g., 'metosin/reitit')"
           },
           "version": {
             "type": "string",
             "description": "Version to check (e.g., '0.7.2')"
           }
         },
         "required": ["dependency", "version"]
       }
     }
     

These tools are designed to facilitate the management of dependencies in AI applications, ensuring that the latest and most relevant artifacts are always used.

⚙️ MCP Architecture & Protocol Implementation

The Clojars MCP Server is built using industry-standard practices to ensure seamless integration with MCP clients. The server follows the Model Context Protocol (MCP) architecture, which provides a standardized API for AI applications to connect with external tools and data sources.

🚀 Getting Started with Installation

To get started quickly:

Installing via npx

1. Run the server directly with npx:

   npx clojars-deps-server
   

2. Install globally:

   npm install -g clojars-deps-server
   

For manual installation:

1. Clone the repository and navigate to the project directory:

   git clone https://github.com/yourusername/clojars-deps-server.git
   cd clojars-deps-server
   

2. Install dependencies:

   npm install
   

3. Build the server:

   npm run build
   

4. Add the server to your Claude configuration (VSCode):

{
  "mcpServers": {
    "clojars-deps-server": {
      "command": "node",
      "args": ["/path/to/clojars-deps-server/build/index.js"]
    }
  }
}

For the Claude Desktop app, add to claude_desktop_config.json:

{
  "mcpServers": {
    "clojars-deps-server": {
      "command": "node",
      "args": ["/path/to/clojars-deps-server/build/index.js"]
    }
  }
}

After adding the server configuration, Claude will automatically detect and connect to the server on startup.

💡 Key Use Cases in AI Workflows

1. Dependency Management: Developers can use this tool to ensure that their projects are always up-to-date with the latest stable versions of dependencies.
2. Automated Version Checking: AI applications can automate the process of checking for new or updated versions of required libraries, streamlining development and maintenance.

🔌 Integration with MCP Clients

The Clojars MCP Server is compatible with several popular MCP clients:

• Claude Desktop (✅)
• Continue (✅)
• Cursor (❌)

This compatibility allows developers to integrate the server into their workflows without any additional setup, making dependency management faster and more efficient.

Continue	✅	✅	✅	Full Support
Cursor	❌ (no MCP support)	✅ (tools only)	❌ (prompting not supported)	Tools Only

🛠️ Advanced Configuration & Security

To configure the server, you can customize the mcpServers section in your Claude configuration. Here's an example:

{
  "mcpServers": {
    "clojars-deps-server": {
      "command": "node",
      "args": ["/path/to/clojars-deps-server/build/index.js"]
    }
  }
}

Ensure that you manage the API keys and other sensitive data securely.
