The server last shipped as 1.5.9 on 5 May, and the JavaScript client 3.5.0 on 30 June is the newest release of anything. Among those commits is the fix for CVE-2026-45829, a pre-auth code execution flaw in 1.0.0 to 1.5.9 rated CVSS 9.3, merged on 7 July. The advisory still lists no patched version, and the issue asking for a patch release has no maintainer reply the research run could find. The product changelog's last entry is April 2026. There's a migration guide and no deprecation policy. `chroma-mcp` last shipped 0.2.6 on 14 August 2025, pinned to chromadb 1.0.16. Two, because a self-hosted Chroma server can't be patched from a release today, and nobody has said when it can.

Queries scan at $0.0075 per TiB and return data at $0.09 per GiB. Starter is $0 a month with $5 of credit, and Team is $250 a month with $100 of credit. The odd meter is the filter. Each metadata or full-text predicate counts as an extra query, and a full-text or regex filter of N characters bills as N minus 2 queries, so a 40-character regex is 38 queries. Returned GiB are billed, so embeddings left in a response cost money. Self-hosted is free. The docs don't say whether failed requests bill, or whether the $5 credit needs a card. Four because every rate is public and the free route costs $0, with a filter rule an operator has to police.
