## 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

### Weaviate API + MCP

1. Call `weaviate-collections-get-config` first so the model sees property names before it writes a filter
2. `weaviate-query-hybrid` defaults `alpha` to 0.75, so lower it for keyword-heavy queries
3. Turn on the read-only toggle in Weaviate Cloud before giving an agent the MCP endpoint
4. Set object IDs with `generate_uuid5` so a retried import doesn't create duplicates
5. Free clusters hold one collection. Use tenants rather than extra collections
