Aiven MCP server

This MCP server provides access to Aiven services (PostgreSQL, Kafka, ClickHouse, Valkey, and OpenSearch) through the Model Context Protocol, enabling large language models to interact with and build solutions using your Aiven infrastructure.

Installation & Configuration

Setting Up with Claude Desktop

1. Open the Claude Desktop configuration file:

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

2. Add the following configuration:

{
  "mcpServers": {
    "mcp-aiven": {
      "command": "uv",
      "args": [
        "--directory",
        "$REPOSITORY_DIRECTORY",
        "run",
        "--with-editable",
        "$REPOSITORY_DIRECTORY",
        "--python",
        "3.13",
        "mcp-aiven"
      ],
      "env": {
        "AIVEN_BASE_URL": "https://api.aiven.io",
        "AIVEN_TOKEN": "$AIVEN_TOKEN"
      }
    }
  }
}

3. Replace the placeholders:

   • $REPOSITORY_DIRECTORY: Path to the folder containing the repository
   • $AIVEN_TOKEN: Your Aiven authentication token

4. Find the absolute path to your uv executable (use which uv on macOS) and update the command entry accordingly.

5. Restart Claude Desktop to apply the changes.

Setting Up with Cursor

1. Navigate to Cursor → Settings → Cursor Settings

2. Select "MCP Servers"

3. Add a new server with:

   • Name: mcp-aiven
   • Type: command
   • Command: uv --directory $REPOSITORY_DIRECTORY run --with-editable $REPOSITORY_DIRECTORY --python 3.13 mcp-aiven

4. Replace $REPOSITORY_DIRECTORY with the path to the repository

5. Add the required environment variables:

   • AIVEN_BASE_URL
   • AIVEN_TOKEN

Using the MCP Server

Available Tools

The server provides the following tools for interacting with your Aiven services:

• list_projects: View all projects in your Aiven account
• list_services: See all services within a specific Aiven project
• get_service_details: Retrieve detailed information about a specific service

Required Environment Variables

To use the MCP server, ensure you've set these environment variables:

• AIVEN_BASE_URL: The Aiven API URL (typically https://api.aiven.io)
• AIVEN_TOKEN: Your authentication token for accessing Aiven services

Testing the Server

For quick testing, you can run:

mcp dev mcp_aiven/mcp_server.py

Security Considerations

When using this MCP server:

• The server runs in your local environment, not hosted by Aiven
• AI agent access is limited by the permissions of your API token
• Follow the principle of least privilege when creating API tokens
• Be cautious when providing credentials to AI agents
• Regularly rotate your API tokens

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 "mcp-aiven" '{"command":"uv","args":["--directory","$REPOSITORY_DIRECTORY","run","--with-editable","$REPOSITORY_DIRECTORY","--python","3.13","mcp-aiven"],"env":{"AIVEN_BASE_URL":"https://api.aiven.io","AIVEN_TOKEN":"$AIVEN_TOKEN"}}'

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": {
        "mcp-aiven": {
            "command": "uv",
            "args": [
                "--directory",
                "$REPOSITORY_DIRECTORY",
                "run",
                "--with-editable",
                "$REPOSITORY_DIRECTORY",
                "--python",
                "3.13",
                "mcp-aiven"
            ],
            "env": {
                "AIVEN_BASE_URL": "https://api.aiven.io",
                "AIVEN_TOKEN": "$AIVEN_TOKEN"
            }
        }
    }
}

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": {
        "mcp-aiven": {
            "command": "uv",
            "args": [
                "--directory",
                "$REPOSITORY_DIRECTORY",
                "run",
                "--with-editable",
                "$REPOSITORY_DIRECTORY",
                "--python",
                "3.13",
                "mcp-aiven"
            ],
            "env": {
                "AIVEN_BASE_URL": "https://api.aiven.io",
                "AIVEN_TOKEN": "$AIVEN_TOKEN"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
