v2.2.0 — August 31, 2026

Release notes for installer and public skills plugin v2.2.0 — Kiro support, durable capture, and safer memory guidance.

This release covers version 2.2.0 of the @yugabytedb/meko-mcp installer and the public Meko agent skills plugin. The installer, public plugin, and Meko MCP server now release independently, so client wiring and agent guidance no longer wait for a server release.

Published skill versions: meko-mcp-tools 3.1.0, meko-mcp-tools-desktop 2.8.0, meko-select-datapack 1.1.2, and meko-select-datapack-desktop 1.2.1.

Install or upgrade

npx @yugabytedb/meko-mcp@2.2.0

Claude Code users can also update the skills plugin directly.

See the installer 2.2.0 release for the Desktop extension and release audit evidence. The public plugin source is in yugabyte/meko-skills.

Changes

New features

  • Kiro IDE and CLI support — --client kiro configures the shared Kiro MCP and skills locations, installs durable hooks for both Kiro hook formats, and supports $KIRO_HOME. The kiro-cli and kiro-ide aliases select the same client.
  • Durable capture with visible status — Claude Code, Cursor, Codex, and Kiro keep failed exchanges in a local outbox and retry them without marking the transcript as saved. Run npx @yugabytedb/meko-mcp@2.2.0 --capture-status or add --json for machine-readable health.

Improvements

  • Independent release versions — the npm installer and Desktop extension advance together. The public skills plugin and Meko MCP server keep their own versions.
  • Safer agent guidance — the skills distinguish failed searches from empty results, treat memory_get_all as a recent window instead of an export, limit the evidence passed into model context, and verify writes before reporting success.
  • Production-safe retrieval guidance — agents use memory_search for personal memory and knowledgebase_search for shared datapack knowledge. The published skills don't direct agents to unreleased retrieval tools.
  • Current memory contracts — memory_search uses semantic, keyword, and entity signals. run_id filters memory reads and deletes by conversation; writes still use conversation_id for trace scope.
  • Working Codex capture and migration — Codex transcripts now use the codex:<repo> agent ID, hold incomplete turns for retry, and migrate historical rollout files.

Fixes

  • Backspace works in the API-key prompt — interactive entry now treats both terminal erase byte forms as Backspace instead of saving them in the key.
  • Claude Desktop startup — automated installs require Node.js 20.18.1 or newer and pin mcp-remote@0.1.38 to prevent “Server disconnected” failures.
  • Migration dry runs stay read-only — --migrate --dry-run no longer creates migration progress or run state.
  • Claude Desktop uninstall instructions — config-file installs, OAuth connectors, and imported Desktop skills now have separate removal steps.

Known limitations

  • Kiro hooks expose the user prompt and final assistant response. Kiro doesn't expose tool calls or hidden reasoning through these hooks, so Meko can't capture them automatically.
  • Claude Desktop has no session hooks. Automatic capture still depends on the selected model following the installed skill and profile instructions.
  • memory_get_all returns a recent window and a total count. MCP doesn't currently provide a complete memory export.
