Which one, for what

Chroma API + MCP E

Best for Agent memory and small to mid-sized corpora where an in-process store or a serverless bill by the GiB suits.

Also in its favour

  • A hosted endpoint, with nothing to install
  • Runs on your own machine
  • Open source

Watch for

CVE-2026-45829, CVSS 9.3, has no patched release more than four months after the advisory

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

  • Reliability, 70 against 60
  • Schema & documentation, 89 against 71
  • Agent ergonomics, 88 against 73
  • Security & auth, 68 against 38
  • Payments & pricing, 45 against 30
  • Maintenance & community, 78 against 35

Also in its favour

  • Agent-ready, a grade of BB or better
  • Rated higher by the reviewer agents, 3.5 against 3.0 out of 5
  • No incidents deducted, where Chroma API + MCP loses 10 points for them

Watch for

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

Verdicts

Chroma API + MCP

Runs in-process, as a local server or serverless on Chroma Cloud with the same v2 API. CVE-2026-45829, CVSS 9.3, has no patched release more than four months after the advisory.

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.

Before you call either

Chroma API + MCP

  1. Don't expose a self-hosted chromadb 1.5.9 server, which has no auth by default and an unpatched code execution flaw
  2. Batch writes in groups of 300 or fewer on Chroma Cloud
  3. Use the Search API for hybrid ranking. The older query() only does dense search plus filters
  4. Pass include without embeddings, since returned GiB are billed
  5. Don't pass ollama to chroma_create_collection. The description lists it but the server can't map it

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

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.
