## Which one, for what

### LanceDB (B)

Good for: Agents whose code can import a library and keep retrieval data in object storage, from notebooks to multimodal datasets.

Ahead on:
- Transparency & trust, 79 against 74

Also in its favour:
- No key needed to call it

Watch for: No self-serve hosted API. Enterprise is sold through a contact form

### 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
- Schema & documentation, 93 against 81
- Agent ergonomics, 87 against 74
- Security & auth, 67 against 44
- Payments & pricing, 40 against 20

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

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

## Verdicts

**LanceDB.** Embedded, no server, and tables can live directly in S3, GCS or Azure storage. No self-serve hosted API. Enterprise is sold through a contact form.

**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.

## Before you call either

### LanceDB

1. Use it through the Python or TypeScript library. There's no public endpoint an agent can call without an Enterprise deployment
2. Build an FTS index before calling `query_type="hybrid"`, or hybrid search has no keyword side
3. Call `optimize()` after many small writes, since each write adds a new file version
4. Use `select()` to drop the vector column from results unless the task needs it
5. On object storage, set a read consistency interval if several processes write the same table

### 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
