Summary
On August 7, 2026 OpenAI shipped Codex 0.147.0, adding support for portable Agent Plugins: installable plugin manifests, workspace plugin publishing, and search across local, personal, workspace, and remote catalogs, including additional plugin marketplaces for Amazon Bedrock and Claude Code. The release also added a --approve-for-me CLI flag for automatically reviewed approvals and adopted the MCP 2026-07-28 protocol.
What changed
Codex 0.147.0 introduced a portable Agent Plugins system (manifests, workspace publishing, cross-catalog search) with new marketplaces for Amazon Bedrock and Claude Code, plus a --approve-for-me flag for auto-reviewed approvals and MCP 2026-07-28 support.
Why it matters
By making plugins portable and listing them in marketplaces tied to Amazon Bedrock and even a rival like Claude Code, OpenAI pushes coding-agent extensions toward a cross-vendor ecosystem rather than a walled garden, which raises the value of writing one plugin once and lowers lock-in for teams standardizing on a plugin format.
