## Which one, for what

### Meilisearch (A)

Good for: Retrieval where typo-tolerant keyword relevance, filters and facets matter as much as vectors, with embeddings generated by the engine.

Ahead on:
- Reliability, 90 against 75
- Maintenance & community, 93 against 87

Also in its favour:
- Open source

Watch for: The `/mcp` route is an experimental feature that must be switched on, and its four tools carry no read-only annotations

### 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:
- Agent ergonomics, 93 against 87
- Security & auth, 79 against 67

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

## Verdicts

**Meilisearch.** Keyword, vector and hybrid search share one request, behind keys scoped by action and index and a published OpenAPI 3.1 file with 143 operations. The built-in MCP server is experimental and read-only, and Cloud access starts with a browser sign-up and a 14-day trial.

**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.

## Before you call either

### Meilisearch

1. Create a key with only `search`, `documents.get` and `indexes.get` on the indexes needed. The default search key fails `listIndexes` and `describeIndex` over MCP
2. Enable the `mcpRoute` experimental feature first. Until then `/mcp` answers `feature_not_enabled`
3. For hybrid search send `hybrid` with an `embedder` name configured in the index settings and a `semanticRatio` from 0 to 1
4. Writes return a `taskUid` and run asynchronously. Poll the task before searching for the new documents
5. On 503 `too_many_search_requests`, wait for the `Retry-After` header (10 seconds) before retrying

### 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
