## Which one, for what

### Pinecone API + MCP (BB)

Good for: Teams that want a hosted index with nothing to run, hosted embedding and reranking, and a versioned API agents can rely on.

Ahead on:
- Schema & documentation, 94 against 58
- Agent ergonomics, 93 against 80

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

Watch for: Nine regional incidents between 9 July and 28 September 2026, four lasting more than an hour

### Vespa (BB)

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

Ahead on:
- Reliability, 80 against 75
- Transparency & trust, 85 against 73

Also in its favour:
- Open source

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

## Verdicts

**Pinecone API + MCP.** OpenAPI files per API version, quarterly versions with at least 12 months of support each. Nine regional incidents between 9 July and 28 September 2026, four lasting more than an hour.

**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

### Pinecone API + MCP

1. Send `X-Pinecone-Api-Version: 2026-07` on every call. Without it you get the oldest supported version
2. Queries go to the index host from `describe_index`, not to api.pinecone.io
3. Wait a few seconds and retry when fresh upserts don't show up in search
4. Back off exponentially on 429. There's no `Retry-After` header
5. Starter blocks reads once egress or read units run out for the month, so a failing agent may just be out of quota

### 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
