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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
