Clojars Dependency Versions MCP server for AI agents

The Clojars MCP Server provides tools for fetching dependency information from Clojars, the Clojure community's artifact repository. It integrates with AI assistants like Claude, Cline, Roo Code, and Cody through the Model Context Protocol (MCP).

Installation Options

Quick Start with npx

The simplest way to use Clojars MCP Server is to run it directly with npx:

npx clojars-deps-server

Global Installation

For regular use, install the server globally:

npm install -g clojars-deps-server

Using Smithery

Install Clojars Dependency Server automatically via Smithery:

npx -y @smithery/cli install clojars-deps-server --client claude

Manual Installation

Follow these steps for a manual installation:

Clone the repository:

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

Install dependencies:
```
npm install
```
Build the server:
```
npm run build
```
Configure in your AI assistant:

For VSCode Claude extension

Add to cline_mcp_settings.json (typically at ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/ on macOS):
```
{
  "mcpServers": {
    "clojars-deps-server": {
      "command": "node",
      "args": ["/path/to/clojars-deps-server/build/index.js"]
    }
  }
}
```
For Claude desktop app

Add to claude_desktop_config.json (typically at ~/Library/Application Support/Claude/ on macOS):
```
{
  "mcpServers": {
    "clojars-deps-server": {
      "command": "node",
      "args": ["/path/to/clojars-deps-server/build/index.js"]
    }
  }
}
```

Usage

Once configured, Claude will automatically detect and connect to the server. The server provides three main tools:

Getting the Latest Version

Use this tool to retrieve the latest version of any Clojars dependency:

{
  "name": "get_clojars_latest_version",
  "dependency": "metosin/reitit"
}

Checking if a Version Exists

Verify if a specific version of a dependency is available:

{
  "name": "check_clojars_version_exists",
  "dependency": "metosin/reitit",
  "version": "0.7.2"
}

Retrieving Version History

Get the version history of a dependency:

{
  "name": "get_clojars_history",
  "dependency": "metosin/reitit",
  "limit": 5
}

The limit parameter is optional (default: 15, max: 100) and controls how many versions to return.

When working with Claude, you don't need to format these requests manually. Claude will recognize when to use these tools based on your questions about Clojars dependencies and will handle the interaction with the MCP server automatically.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "clojars-deps-server" '{"command":"npx","args":["clojars-deps-server"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "clojars-deps-server": {
            "command": "npx",
            "args": [
                "clojars-deps-server"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "clojars-deps-server": {
            "command": "npx",
            "args": [
                "clojars-deps-server"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
