Cursor

  1. Download and install Cursor from cursor.sh
  2. Open Cursor and open the project you wish to add the MCP server to
  3. Create a .cursor directory in the root of your workspace (if not present already)
  4. Create a mcp.json file inside the .cursor directory
  5. Add the MCP configuration to mcp.json based on the server deployment method you chose earlier

MCP configurations

Python (Local)

{
  "mcpServers": {
    "Atlan MCP": {
      "command": "uv",
      "args": [
        "run",
        "/path/to/your/agent-toolkit/modelcontextprotocol/.venv/bin/atlan-mcp-server"
      ],
      "env": {
        "ATLAN_API_KEY": "your_api_key",
        "ATLAN_BASE_URL": "https://your-instance.atlan.com",
        "ATLAN_AGENT_ID": "your_agent_id"
      }
    }
  }
}

Note:

  • Make sure to replace /path/to/your/agent-toolkit with the actual path to your cloned repository
  • Replace your_api_key, your_instance, and your_agent_id with your actual Atlan API key, instance URL, and agent ID(optional) respectively

Container (Local)

{
  "mcpServers": {
    "atlan": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "ATLAN_API_KEY=your_api_key",
        "-e",
        "ATLAN_BASE_URL=https://your-instance.atlan.com",
        "-e",
        "ATLAN_AGENT_ID=your_agent_id",
        "atlan-mcp-server:latest"
      ]
    }
  }
}

Note:

  • Make sure to replace your_api_key, your_instance, and your_agent_id with your actual Atlan API key, instance URL, and agent ID(optional) respectively

Production Deployment

  • Host the Atlan MCP container image on the cloud/platform of your choice
  • Make sure you add all the required environment variables
  • Make sure you start the server in the SSE transport mode -e MCP_TRANSPORT=sse

MCP configuration

Even though Claude Desktop/Cursor don't yet support remote MCP clients, you can use the mcp-remote local proxy to connect it to your remote MCP server. This lets you to test what an interaction with your remote MCP server will be like with a real-world MCP client.

{
  "mcpServers": {
    "math": {
      "command": "npx",
      "args": ["mcp-remote", "https://hosted-domain"]
    }
  }
}

Troubleshooting

  1. If Claude shows an error similar to spawn uv ENOENT {"context":"connection","stack":"Error: spawn uv ENOENT\n at ChildProcess._handle.onexit, it is most likely this issue where Claude is unable to find uv. To fix it:
    • Make sure uv is installed and available in your PATH
    • Run which uv to verify the installation path
    • Update Claude's configuration to point to the exact uv path by running whereis uv and use that path
