OpenAI Codex CLI rust-v0.147.0 adds Agent Plugins and MCP 2026-07-28 support
OpenAI
Codex CLI rust-v0.147.0 adds installable Agent Plugins searchable across local, personal, workspace, and remote catalogs, support for the opt-in MCP 2026-07-28 protocol (paginated discovery, non-blocking server startup), and secret/bearer-token redaction in displayed commands and replayed history. It also removes the deprecated `codex exec --full-auto` flag in favor of `--sandbox workspace-write`, following yesterday's 0.146.1 auto-review hardening.
Why it matters
Agent Plugins and multi-catalog discovery push Codex CLI toward the same extensibility model Claude Code and OpenCode have been building out, while the redaction fix closes a credential-leak risk in session logs.
Importance: 2/5
Notable feature update (Agent Plugins, new MCP protocol support) plus a credential-leak fix, continuing yesterday's patch series.
