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.\n\n**OpenSearch.** OpenSearch 3.9.0 runs vector, text and hybrid search under Apache-2.0, with an OpenAPI 3.1 description of its REST API and API keys limited by permission and index pattern. The owner runs the cluster, no status page or SLA comes with the software, and no tool in the MCP server sets a read-only or destructive annotation.\n\n## Before you call either\n\n### Cloudflare AI Search\n\n1. Use `/ai-search/namespaces/default/instances/{id}/search`. The un-namespaced and `/autorag/rags/` paths are deprecated\n2. 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\n3. On 429 code 7069 the monthly query quota is spent. Wait or upgrade rather than retry\n4. 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\n5. Filters match only the first 64 bytes of a string. Use a `$gte`/`$lt` range on `folder` to match a folder and its subfolders\n\n### OpenSearch\n\n1. Create the index with `index.knn` set to true and a `knn_vector` field of the right dimension before indexing vectors\n2. Put the `filter` clause inside the `knn` query for filtering during the search. A filter outside it runs afterwards and can return fewer than `k` hits\n3. Ask a security administrator for an API key and send it as `Authorization: ApiKey \u003ctoken\u003e`. The token is shown once and lasts 90 days at most\n4. Use `size`, `_source` and `filter_path` to keep responses small, and `search_after` with a point in time for deep paging\n5. Set `OPENSEARCH_SETTINGS_ALLOW_WRITE=false` on the MCP server unless writes are needed. `GenericOpenSearchApiTool` can call any endpoint\n\n## Questions\n\n### Which is better for AI agents, Cloudflare AI Search or OpenSearch?\n\nCloudflare AI Search scores 73.5 (BB) on agent readiness against OpenSearch's 68 (B), and leads in 3 of 7 scored categories. OpenSearch leads on reliability, payments \u0026 pricing and maintenance \u0026 community.\n\n### Which is cheaper for db hybrid, Cloudflare AI Search or OpenSearch?\n\nOpenSearch, at free against $0.75 per 1,000 requests for Cloudflare AI Search. These are the vendors' published prices for the job.\n\n### Do Cloudflare AI Search and OpenSearch need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Cloudflare AI Search and OpenSearch without installing anything?\n\nNo hosted endpoint is listed for Cloudflare AI Search. OpenSearch runs on your own machine, with no hosted endpoint listed.\n\n### Are Cloudflare AI Search and OpenSearch open source?\n\nNo open-source release is listed for Cloudflare AI Search. OpenSearch is open source (Apache-2.0 for the engine, the plugins, the clients, the API specification and the MCP server).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/cloudflare-ai-search-vs-opensearch.json, and with the fewest tokens: https://www.anchorterminal.com/compare/cloudflare-ai-search-vs-opensearch.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"cloudflare-ai-search\", \"b\": \"opensearch\"}`.
