## Which one, for what

### Qdrant API + MCP (BB)

Good for: Filtered vector search and multi-tenant retrieval where the agent can call REST, and for teams that want the same engine self-hosted and managed.

Ahead on:
- Schema & documentation, 87 against 58
- Agent ergonomics, 87 against 80
- Security & auth, 83 against 75

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

Watch for: The MCP server has 2 tools, can't manage collections or run filtered queries, and last released on 10 December 2025

### Vespa (BB)

Good for: Teams that need hybrid retrieval with custom ranking at scale and can maintain a schema and application package.

Ahead on:
- Payments & pricing, 40 against 30
- Maintenance & community, 91 against 85

Watch for: No OpenAPI file was found in the docs index. The APIs are described in reference pages only

## Verdicts

**Qdrant API + MCP.** Database keys can be read-only, limited to chosen collections and expire after 90 days by default. The MCP server has 2 tools, can't manage collections or run filtered queries, and last released on 10 December 2025.

**Vespa.** Vespa Cloud publishes hourly unit prices, a 99.5% uptime agreement for paying customers and a trial with $300 of credits and no card. Every call needs an application package deployed first, no OpenAPI file was found in the reviewed documentation, and Vespa.ai says it has no official public MCP server.

## Before you call either

### Qdrant API + MCP

1. Create payload indexes on the fields you filter on, or filtered search slows on large collections
2. Use `/points/query` with `prefetch` to fuse dense and BM25 results
3. Pass `wait=true` on upserts when the next step reads its own writes
4. On 429, wait for the `Retry-After` seconds before retrying
5. Set `with_vector=false` unless the task needs vectors, since they dominate response size

### Vespa

1. Deploy an application package with a schema before feeding or querying. Use `vespa deploy` and wait for the endpoint to report ready
2. Send a token as `Authorization: Bearer` only to the endpoint marked Token. The mTLS endpoint needs the client certificate and key
3. Set `hits`, `offset` and `presentation.summary` on queries. `hits` is capped at 400 by default and the query timeout defaults to 0.5s
4. On 429 from `/document/v1` reduce the feed rate and back off. On 507 stop feeding, because the cluster is out of memory or disk
5. Use the `condition` parameter for test-and-set writes and expect 412 when it fails or the document is missing
