Navigate your Aiven projects and interact with the PostgreSQL®, Apache Kafka®, ClickHouse® and OpenSearch® services
Aiven mcp server lets Claude, Cursor and other MCP clients work with Aiven directly. Navigate your Aiven projects and interact with the PostgreSQL®, Apache Kafka®, ClickHouse® and OpenSearch® services.
A Model Context Protocol (MCP) server for the Aiven cloud data platform.
Once connected, the assistant can call these 5 tools directly:
Core — The Core tool exposed by this serverKafka — The Kafka tool exposed by this serverPostgreSQL — The PostgreSQL tool exposed by this serverApplications — The Applications tool exposed by this serverDocumentation — The Documentation tool exposed by this serverThe server is distributed via npm as mcp-aiven, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Before the server will start you need to supply 3 environment variables: AIVEN_TOKEN, YOUR_TOKEN, MCP_EDGE_AUTH_SECRET. Keep credentials in your client's env block or a secrets manager rather than committing them.
Database servers turn schema archaeology and ad-hoc reporting into conversation, which is why they tend to be the second or third server people install. Aiven sits in that group, and the shape of its toolset — Core, Kafka, PostgreSQL among others — tells you what it is really for. Worth comparing against the other databases servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
