Best for
  • Developers and ops teams already on Aiven who want AI-assisted resource management
  • Teams managing both PostgreSQL and Kafka
  • Security-conscious users who want a reduced tool surface (read-only, scoped)
  • Teams already using ClickHouse who want AI assistants to access data directly.
  • Scenarios requiring fast, read-only data queries and schema exploration.
Not for
  • Users not on the Aiven platform
  • Production environments where AI agents must not perform destructive actions (dropping databases, deleting services)
  • Self-hosted/local deployments, which cannot use the aiven_docs_search tool
  • Scenarios requiring write access to the database without explicit opt-in.
  • Production environments with stringent security requirements that avoid default permission settings.
Required permissions
  • Local stdio mode requires an Aiven API token (AIVEN_TOKEN)
  • Remote mode uses OAuth authorization; access is governed by the Aiven user permissions of the authenticated account
  • The server can only perform actions the Aiven user is allowed to do
  • Requires read-only access to ClickHouse database (default).
  • Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
  • Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
Risks and side effects
  • AI agents may execute destructive actions (dropping databases, deleting services, producing messages) based on their interpretation of prompts
  • With AIVEN_ALLOW_SECRETS enabled, the connection-info tool returns live credentials (passwords, connection URIs, certs) into the conversation
  • Review agent behavior, perform a risk assessment, and follow your organization's security policies before using in production
  • If write access is enabled, AI might make unintended modifications.
  • If DROP access is enabled, data deletion could occur accidentally.
  • Credentials may be exposed via environment variables.
