Aiven MCP Server

A Model Context Protocol (MCP) server for the Aiven cloud data platform.

Manage PostgreSQL, Apache Kafka, applications, and other Aiven services directly from AI assistants like Claude, Cursor, and VS Code Copilot.

[!WARNING] Use with care. This MCP server can create, modify, and delete Aiven services and data on your behalf. AI agents may execute destructive actions (dropping databases, deleting services, producing messages) based on their interpretation of your prompts. You are fully responsible for the actions taken through this tool.

Permissions: Access is governed by the Aiven user permissions associated with the authenticated account. The MCP server can only perform actions that your Aiven user is allowed to do.

AI Agent Security: AI agents may need access credentials (database connection strings, streaming tokens) to act on your behalf. Review what your agent is doing, especially in production environments. Follow your organization's security policies and do a risk assessment before giving AI agents access to sensitive resources.

Quick Start

Option 1: Remote (hosted by Aiven)

The MCP server is hosted at https://mcp.aiven.live/mcp. Your MCP client will prompt you to authorize on Aiven.

Claude Code

claude mcp add --scope user --transport http aiven-mcp "https://mcp.aiven.live/mcp"

Cursor

Or manually add to Cursor MCP settings:

{
  "mcpServers": {
    "aiven-mcp": {
      "url": "https://mcp.aiven.live/mcp"
    }
  }
}

VS Code / Copilot

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "aiven-mcp": {
      "type": "http",
      "url": "https://mcp.aiven.live/mcp"
    }
  }
}

Read-Only Mode (Remote)

Enable read-only mode by adding ?read_only=true to the URL. All write operations will be excluded from the MCP:

{
  "mcpServers": {
    "aiven-mcp": {
      "url": "https://mcp.aiven.live/mcp?read_only=true"
    }
  }
}

Option 2: stdio (local)

Run the server locally as a child process of your MCP client. Requires Node.js 18+.

You must provide your Aiven API token via the AIVEN_TOKEN environment variable. Create a token here.

Claude Code

claude mcp add --scope user aiven-mcp -e AIVEN_TOKEN=your-token-here -- npx -y mcp-aiven

Cursor, VS Code -- add to your MCP client config:

{
  "mcpServers": {
    "aiven-mcp": {
      "command": "npx",
      "args": ["-y", "mcp-aiven"],
      "env": {
        "AIVEN_TOKEN": "your-token-here"
      }
    }
  }
}

Config file locations:

• Cursor: Cursor Settings > MCP Servers
• VS Code: .vscode/mcp.json in your workspace

Environment Variables

Variable	Required	Default	Description
AIVEN_TOKEN	stdio only	--	Aiven API token (create one here)
AIVEN_READ_ONLY	No	false	Set to true to expose only read-only tools

In remote (HTTP) mode, AIVEN_TOKEN is not needed. Your MCP client sends your token as a Bearer token with each request.
