# kx-mcp-kdbai — KDB.AI backend The KDB.AI backend extension (bundle) for the [KX MCP composition container](https://github.com/KxSystems/kx-mcp-server-container). It exposes database/table introspection, structured query, and vector + hybrid search over a KDB.AI service via the [`kdbai-client`](https://pypi.org/project/kdbai-client/) SDK, and is packaged as a standard container bundle: a package exposing `build_server() -> FastMCP`, mounted under the `kdbai` namespace. It is **mount-only**: the composition container (`kx-mcp-core`) owns transport/host/port, so the bundle has no standalone server of its own — `build_server()` just returns a configured FastMCP to `mount()`. Run it via the container: `uv run kx-mcp --bundles kdbai`. > The bundle connects to a **KDB.AI** service. Unlike the kdb-x backend, it does **not** require a > PyKX license — `kdbai-client` owns connectivity (qIPC or REST). ## Table of contents - [Prerequisites](#prerequisites) - [KDB.AI setup](#kdbai-setup) - [Configuration](#configuration) - [Configure embeddings](#configure-embeddings) - [Capabilities](#capabilities) - [Running the backend](#running-the-backend) - [Troubleshooting](#troubleshooting) ## Prerequisites - **A reachable KDB.AI Server** on a host and port the MCP server can reach. The bundle's default is **`127.0.0.1:8082`** in **`qipc`** mode; selecting `rest` without an explicit port uses **`127.0.0.1:8081`**. See the [KDB.AI documentation](https://code.kx.com/kdbai/latest/) to install / run a server. - **[UV](https://docs.astral.sh/uv/getting-started/installation/)** to run the server. - **`kdbai-client>=2.0.0`** (pulled in automatically with this bundle). The MCP host needs no `QLIC` / PyKX license; the KDB.AI Server deployment owns its own licensing. ## KDB.AI setup Start (or point at) a KDB.AI Server, then configure the endpoint via `KDBAI_DB_*` (below); running the container with this bundle performs its eager mount-time pre-flight.
