GBrain upgrades memory-agent fleet: MCP tools grow to 33, multiple security fixes shipped
garrytan · x · 2026-09-30
GBrain has upgraded every workspace to OpenClaw 2026.9.6 and GBrain 0.59.3.
Versions and stack
- OpenClaw 2026.8.2 → 2026.9.6, GBrain 0.48.0 → 0.59.3, Node.js 22 → 24
- MCP server tools grew from 27 to 33, adding skills and write-receipt tools
- ZeroEntropy embedding provider removed; memory now embedded with OpenAI models
- Nightly memory consolidation staggered per workspace (03:00–07:00 UTC) instead of a global 03:00 run
Behavior changes
- Post-upgrade, GBrain rewrites every memory page; search may briefly miss pages, large workspaces take hours
- Overwriting an existing page via MCP or CLI now requires the page's current revision (or force), preventing concurrent write conflicts
Security fixes
- OpenClaw: config reads no longer expose secrets, DNS checks on proxied requests, authorized metrics endpoint, anti-impersonation
- GBrain: stricter memory access, owner consent for OAuth grants, outbound fetch checks, secret redaction
