Which one, for what

Cloudflare AI Search BB

Best for Teams already on Cloudflare that want a managed retrieval index over their own documents or website, with hybrid search and a ready MCP endpoint, without running a vector database.

Ahead on

  • Payments & pricing, 45 against 40

Watch for

Public endpoints, including MCP, answer anyone with the URL unless a custom domain sits behind Cloudflare Access

Pinecone API + MCP BB

Best 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

  • Reliability, 75 against 70
  • Schema & documentation, 94 against 89
  • Agent ergonomics, 93 against 88
  • Security & auth, 79 against 68
  • Maintenance & community, 87 against 78
  • Transparency & trust, 81 against 73

Also in its favour

  • A hosted endpoint, with nothing to install

  • Free to start without a card

Verdicts

Cloudflare AI Search

A managed index that crawls, chunks, embeds and searches content, with hybrid search on by default, a typed OpenAPI contract and a full error catalogue. Generally available since 1 October 2026, with billing from 1 November. Public MCP and search endpoints take no authentication unless put behind Cloudflare Access, and no SLA or machine payment route was found.

Pinecone API + MCP

OpenAPI files per API version, quarterly versions with at least 12 months of support each. Nine regional incidents between 20 July and 14 October 2026, four lasting more than an hour.

Before you call either

Cloudflare AI Search

  1. Use /ai-search/namespaces/default/instances/{id}/search. The un-namespaced and /autorag/rags/ paths are deprecated
  2. Set ai_search_options.retrieval.max_num_results (1 to 50, default 10) and match_threshold (default 0.4) to bound the context you read
  3. On 429 code 7069 the monthly query quota is spent. Wait or upgrade rather than retry
  4. Expect up to six hours before website or R2 changes are searchable. Trigger a sync job, at most once every 30 seconds, after you write
  5. Filters match only the first 64 bytes of a string. Use a $gte/$lt range on folder to match a folder and its subfolders

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. Pinecone Local is gone, so test against a separate project
