marvisx-cli v0.2.3 — MCP write-back fix
Fixes write-back via the MCP server. The OSS MCP server now initializes the DB writer at startup, so an agent can persist to the brain over MCP (create_task, update_task, ...) — previously reads worked but every write failed with DB not initialized. Restores the "every result writes back" promise.
Upgrade: uv tool install -U marvisx-cli
