Open the source and read safety notes before installing.

Safety notes

Write operations (create/update services, deploy apps) are available but require `AIVEN_READ_ONLY=false` — the server defaults to read-only mode.
Aiven services include managed production databases — confirm before creating or modifying services.

Privacy notes

Service metadata, metrics, application logs, PostgreSQL query stats, Kafka topic configurations, and Schema Registry content from your Aiven account are surfaced in Claude's context.
Your `AIVEN_TOKEN` grants account-level API access — keep it in the MCP config env and never commit it to version control.

Prerequisites

An Aiven account — sign up at aiven.io.
An Aiven API token: User Information → Authentication → Generate Token.
Node.js with `npx` available.
An MCP client such as Claude Code or Claude Desktop.

About this resource

Overview

The Aiven MCP Server is the official Model Context Protocol server from Aiven, the managed cloud database platform. It gives Claude access to your Aiven projects and services — PostgreSQL, Apache Kafka, ClickHouse, Valkey (managed Redis), and OpenSearch — for monitoring, diagnostics, query execution, and configuration management. Two install modes: local npx with an API token, or the hosted remote endpoint at https://mcp.aiven.live/mcp using OAuth. Apache-2.0 licensed.

Key capabilities

Project & service management — list/get/create/update projects and services.
Service metrics & logs — fetch metrics, application logs, service events, and query activity.
Apache Kafka — topic CRUD, produce/consume messages, Kafka Connect lifecycle, Schema Registry.
PostgreSQL — execute SQL queries, query statistics, available extensions, PgBouncer pools, query optimization.
Applications — deploy and redeploy Aiven applications, manage VCS integrations.
Cloud & VPC — list available clouds per project, list project VPCs.
Documentation search — query Aiven knowledge base (hosted server mode).

How it compares

Server	PostgreSQL	Kafka	ClickHouse	OpenSearch	Notes
Aiven MCP	Yes	Yes	Yes	Yes	Official, multi-service
Confluent MCP	No	Yes	No	No	Kafka-only, official
Neon MCP	Yes (Neon)	No	No	No	Serverless Postgres only
Turso MCP	No (SQLite)	No	No	No	Edge SQLite only

Aiven MCP is unique in providing a single interface across multiple managed database types — PostgreSQL, Kafka, ClickHouse, OpenSearch, and Valkey — from one API token.

Installation

Claude Code (stdio with API token)

claude mcp add --scope user aiven-mcp \
  -e AIVEN_TOKEN=<your-token> \
  -- npx -y mcp-aiven

Claude Code (hosted HTTP with OAuth)

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

      "env": {
        "AIVEN_TOKEN": "<your-token>"
      }
    }
  }
}

Generate your API token at User Information → Authentication → Generate Token in the Aiven Console.

Configuration options

Env var	Default	Purpose
`AIVEN_TOKEN`	—	Required (stdio mode). Aiven API token
`AIVEN_READ_ONLY`	`true`	Restrict to read-only operations
`AIVEN_SERVICES_SCOPE`	all	Comma-separated filter: `kafka,pg,clickhouse`

Requirements

An Aiven account with at least one service.
Node.js (for npx), or use the hosted remote endpoint.
An MCP client (Claude Code or Claude Desktop).

Security

Read-only by default — set AIVEN_READ_ONLY=false only when you need write operations.
Use AIVEN_SERVICES_SCOPE to expose only the service types you need.
Keep AIVEN_TOKEN in the MCP config env; treat it as an account-level secret.

Source Verification Notes

Verified on 2026-06-18:

Official repository Aiven-Open/mcp-aiven (Apache-2.0) on npm as mcp-aiven (v1.9.2) documents npx -y mcp-aiven, AIVEN_TOKEN/AIVEN_READ_ONLY/AIVEN_SERVICES_SCOPE configuration, stdio and hosted HTTP modes, all service categories (PostgreSQL, Kafka, ClickHouse, Valkey, OpenSearch), and the hosted endpoint at https://mcp.aiven.live/mcp.
Official Aiven MCP documentation at aiven.io/docs/tools/mcp-server (SSR HTML, HTTP 200) describes the integration setup and credential generation.
Claude Code MCP documentation at code.claude.com/docs/en/mcp describes the stdio connector pattern used above.

Safety notes	✓Write operations (create/update services, deploy apps) are available but require `AIVEN_READ_ONLY=false` — the server defaults to read-only mode. Aiven services include managed production databases — confirm before creating or modifying services.	✓The server is read-only by default — SELECT, EXPLAIN, and schema queries only; no INSERT, UPDATE, or DELETE. Write tools (create_database, create_table, insert_rows) can be enabled with explicit opt-in — only enable if needed. DROP and TRUNCATE operations are not supported even with write opt-in.	✓The Fly.io MCP server runs locally with full access to your authenticated Fly.io account — it can create, delete, and modify apps, machines, and secrets. Fly.io warns that running the server remotely can give others access to run commands on your behalf; keep it bound to localhost unless you intend remote access. Destructive operations (machine deletion, secret updates) are available — review Claude's proposed commands before executing in production environments.	✓This server can create payment sessions, generate payment links, cancel authorized payments, and initiate refunds — these are live financial operations. Use `--env=TEST` during development with Adyen's test API keys to avoid live transactions. Restrict enabled tools to only what is needed via the `--tools` parameter (e.g., `--tools=create_session,list_merchants`).
Privacy notes	✓Service metadata, metrics, application logs, PostgreSQL query stats, Kafka topic configurations, and Schema Registry content from your Aiven account are surfaced in Claude's context. Your `AIVEN_TOKEN` grants account-level API access — keep it in the MCP config env and never commit it to version control.	✓Database schemas, table structures, query results, and running query metadata from your CockroachDB Cloud cluster are surfaced in Claude's context. Authentication uses OAuth (browser flow) or a service account API key — keep the API key in the MCP config headers.	✓App names, machine IDs, secret names (not values unless explicitly requested), and log content may be surfaced into Claude's context. Fly.io API tokens (`FLY_ACCESS_TOKEN`) grant full account access — store them in your environment, not in repositories.	✓Payment session data, merchant account details, terminal configurations, and webhook payloads from your Adyen instance are surfaced in Claude's context. Your Adyen API key is passed as a CLI argument — use environment variable substitution (e.g., `--adyenApiKey=${ADYEN_API_KEY}`) to avoid exposing it in config files.
Prerequisites	An Aiven account — sign up at aiven.io. An Aiven API token: User Information → Authentication → Generate Token. Node.js with `npx` available. An MCP client such as Claude Code or Claude Desktop.	A CockroachDB Cloud account with at least one cluster — sign up at cockroachlabs.com. Your cluster ID (from the Cloud Console URL: cockroachlabs.cloud/cluster/YOUR_CLUSTER_ID). An MCP client such as Claude Code or Claude Desktop. Optional: a CockroachDB Cloud service account API key for non-interactive auth.	flyctl installed — see fly.io/docs/flyctl/install/ (Homebrew: `brew install flyctl`) Logged in to Fly.io: `fly auth login` Or set `FLY_ACCESS_TOKEN` environment variable for headless/CI use. An MCP client such as Claude Code or Claude Desktop.	An Adyen account with a web service API key (customer area → Developers → API credentials). The API key user must have appropriate roles: Checkout Webservice, Management API - Accounts Read, Merchant PAL Webservice, and others depending on tools used (see docs). Node.js with `npx` available. An MCP client such as Claude Code or Claude Desktop.
