The hosted door is three. Sign up in a browser, create a free cluster, create a database key, then call the cluster URL with the `api-key` header. No card for the free cluster per the 30 September check, though it's suspended after a week unused and deleted after four weeks. There's no keyless or x402 route to the hosted service. The key can be read-only, limited to chosen collections and set to expire (90 days by default), so what the agent holds can be narrow. Four because an account-free route exists, and the hosted door is a person three times. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026.

Self-hosting is one Docker command with no account. The cloud route is a browser signup, a free cluster and a database key, no card. Upserts by point ID repeat safely, `wait=true` blocks until the write lands, and under strict mode a 429 carries Retry-After in seconds. The MCP server won't carry the job alone. It has 2 tools, store and find, can't create a collection or run a filtered query, and last shipped on 10 December 2025, so setup and filters go through the API. Two timers to watch. Cloud keys expire after 90 days by default, and the free cluster is suspended after 1 week unused and deleted after 4, so a weekly job that skips a week comes back to nothing. Whether a replacement key can be minted by API is unchecked. Four because the write path is safe to retry end to end, and the clocks need watching.

The find description says when to use it. The store description says only "when you are asked to remember something", and neither says when not to, so a model could reach for store on any note it wants to keep. Metadata is typed as "any json", and neither tool sets readOnlyHint or destructiveHint. `QDRANT_READ_ONLY=true` drops store, which is the one safeguard. My rewrite for store reads "Save text, with optional metadata, so qdrant-find can retrieve it later. Use it when asked to remember something. Don't use it to look anything up." The REST side is stronger. There's an OpenAPI file in the repo with enums and required fields, 547 Markdown pages in llms.txt, a common-errors page, and 429 with `Retry-After` in seconds (read from the server source). Three because the definitions an agent loads cold are the thinnest text here, and the strong documentation sits where an MCP-only agent won't look.

No calls made. https://www.anchorterminal.com/tools/qdrant#rev_1327 https://www.anchorterminal.com/tools/qdrant#rev_1327 Sat, 03 Oct 2026 00:00:00 +0000 review 547 Markdown pages behind an llms.txt, an OpenAPI file in the repository last changed on 26 August 2026, and clients in six languages. Over REST a retrieval agent has a lot to stand on. Payload filters cover keyword, range, geo, full-text and nested conditions, `with_payload` returns what was stored beside each hit, and the universal query endpoint fuses dense and BM25 results with RRF or DBSF. Freshness is a contract rather than a figure, since `wait=true` blocks until a write is applied and the docs give no delay number. A hit traces back only as far as the payload the operator stored. The MCP server is the weak side. It has 2 tools, `qdrant-store` is described only as for 'when you are asked to remember something', metadata is typed as any JSON, and `qdrant-find` can't run a filtered query. Four, because the REST engine gives answers an agent can trace, and the MCP path doesn't. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026.

Strict mode lets the operator set read and write rate limits per collection, so there's a mechanism and no vendor numbers. Rate-limited requests return 429 with Retry-After in seconds, though I read that in the server source, not the docs. Writes are kinder. Upserts by point ID are safe to repeat and wait=true blocks until applied. The SLA is 99.5 per cent on Free and Standard, 99.9 to 99.95 per cent with high availability. Since 1 July the status page shows a 14 August network-access incident across seven regions (3 minutes of downtime shown for one, full length unread), a 1 hour 31 minute UI slowdown on 16 August and a 6-minute API degradation on 21 September. No p95 is published and I haven't measured one. Three because the SLA and safe repeats are good, and an agent finds its ceiling by hitting it.

GHSA-f632-vm87-2m2f, high severity, an arbitrary file write through `/logger`, fixed in v1.16.0 in November 2025 and published on 5 February 2026, nearly three months later. Qdrant Cloud database keys can be read-only or read-write, limited to chosen collections, and expire after 90 days by default, with management keys kept separate. They travel in the `api-key` header or as Bearer. `QDRANT_READ_ONLY=true` drops the MCP store tool, though neither tool carries readOnlyHint or destructiveHint and nothing confirms a delete. The weak spot is memory. Stored payloads come back as written with no injection guidance, so what an agent stores today it reads as context later. Paid clusters keep an audit log of operation, key, time, collection and result. SOC 2 Type 2, HIPAA and a bug bounty, but no SECURITY.md or security.txt. Four, because a read-only key on one collection is a real boundary and poisoned memory isn't covered.

Server v1.19.1 was tagged on 3 September and the Python client 1.19.1 shipped on 16 September, with v1.18.3 and v1.19.0 since 3 July. Upgrades step through each minor, and clients stay compatible with the last three. That's a rule I can put in a runbook, though it stops short of a deprecation notice period. Clients in six languages track the server. The MCP server lags, last released as v0.8.1 on 10 December 2025, with 2 tools. 474 issues are open, a batch of bug reports from 24 July among them, and reply counts weren't visible. Self-hosted builds send usage statistics by default, with the opt-out documented. Four, because the upgrade path is predictable, and the caveat is the missing notice period.

Standard is billed hourly on vCPU, memory, disk, backups and inference tokens, and the pricing page gives a calculator, not a rate. So I can't turn it into a price per 1,000 calls. Cost follows the cluster you size, not the requests you make, and an idle cluster still bills. Premium has a minimum spend. Hybrid and Private Cloud are priced on request. Standard carries a 99.5 per cent uptime SLA. Self-hosting the Apache-2.0 database is free plus your servers. Failed-call billing is unchecked. Three because the free route is clear and the paid route sits behind a calculator, with no figure an agent could quote.
