An alpha Qdrant integration for Microsoft Agent Framework. QdrantCollection provides async batch storage and dense-vector search, QdrantStore manages collection clients, and QdrantSettings handles connection configuration.

pip install agent-framework-qdrant --pre

Requires Python 3.10+ and Qdrant server 1.16.2+. The official async qdrant-client SDK is installed automatically.

Set QDRANT_URL to your server URL and optionally QDRANT_API_KEY for authentication. If no URL is supplied, the SDK defaults to localhost.

Both constructors resolve settings from explicit url/api_key arguments, then an optional env_file_path, then environment variables. API keys accept str or AF SecretString and are unwrapped only when creating the SDK client.

You can instead pass a configured AsyncQdrantClient as async_client for advanced SDK options. Supplied clients bypass settings loading and remain caller-owned unless managed_client=True; connector-created clients are closed on async context exit.

This example stores and searches a record using a supplied vector, without an embedding service:

import asyncio
from dataclasses import dataclass
from typing import Annotated

from agent_framework import Filter, VectorStoreField, vectorstoremodel
from agent_framework_qdrant import QdrantStore


@vectorstoremodel
@dataclass
class Document:
    id: Annotated[int, VectorStoreField("key")]
    title: Annotated[str, VectorStoreField("data")]
    embedding: Annotated[
        list[float] | None, VectorStoreField("vector", dimensions=3)
    ] = None


async def main() -> None:
    async with QdrantStore() as store:
        collection = store.get_collection(Document, collection_name="documents")
        await collection.ensure_collection_exists()
        await collection.upsert(
            [Document(1, "Hello Qdrant", [1.0, 0.0, 0.0])],
            generate_vectors=False,
        )
        results = await collection.search(
            vector=[1.0, 0.0, 0.0],
            filter=Filter("title", "eq", "Hello Qdrant"),
            top=3,
        )
        async for result in results:
            print(result["record"].title, result["score"])


asyncio.run(main())

Use get([key], include_vectors=True) to retrieve vectors, or delete([key]) to remove records. Without include_vectors=True, retrieval omits vectors. Batch writes can partially succeed if the server reports an error. Tuple payload values, including nested tuples, are stored as JSON arrays without modifying the input records. Typed models restore tuples through their registered decoder.

Ordered retrieval (order_by) is not supported. Unordered retrieval uses bounded scroll pages without retaining the skipped prefix.

• Keys must be unsigned 64-bit integers or UUIDs (str or uuid.UUID). Arbitrary strings and automatically generated keys are not supported.
• Multiple named dense-vector fields are supported. Binary, sparse, multivector-fusion, and keyword-hybrid search are not supported.
• Vector fields must declare a floating-point element type. Qdrant stores dense vectors as float32; integer-valued inputs remain valid for floating-point fields.
• Scores and thresholds use native Qdrant units. The default is cosine similarity; dot product, Euclidean distance, and Manhattan distance are also supported.
• Portable filters require a server. SDK local mode supports unfiltered storage and dense search, but rejects portable filters and does not build payload indexes.
• Filters support scalar comparisons, collection membership, and AND/OR/NOT. Literal text, nested-path, and array/object-equality filters are unsupported. Numeric range and mixed numeric membership operands are limited to +/- (2**53-1); integer equality supports the full signed 64-bit range.

Start a disposable server using the Qdrant version pinned in CI, then run the integration suite from the python/ directory:

docker run -d --rm --name af-qdrant-test -p 127.0.0.1:16333:6333 qdrant/qdrant:v1.16.2
curl --fail --retry 20 --retry-delay 1 --retry-connrefused http://127.0.0.1:16333/readyz
QDRANT_TEST_URL=http://127.0.0.1:16333 uv run --frozen --directory packages/qdrant poe test-integration -p no:pytest-retry
docker stop af-qdrant-test

Disabling the retry plugin makes failures visible on the first attempt. To run only the concurrent-creation cases, append -k concurrent_collection_creation_validates_winning_schema to the test command. The fixtures create uniquely named collections and delete them after each test.
