Users report that the Postman desktop app automatically installs Codex and Claude plugins

On October 24, 2026, a user filed an issue on GitHub, stating that after opening Postman desktop version 12.33.4, the logs recorded the automatic installation of the Codex plugin 1.1.0 and the Claude Code plugin 2.0.1, and that ~/.codex/config.toml and ~/.claude/settings.json were modified. The user also pointed out that the installed SessionStart hook requires the agent to load the postman:api-engineer skill before handling API engineering tasks, and that the installer source code calls approvePostmanHook in an attempt to write hook trust records on its own. The report also records that the Postman remote MCP failed to start because it requires authentication, and that the Postman CLI appeared in ~/.local/bin. The user said they have uninstalled the local installation and integrations and asked maintainers to handle the matter at critical priority. Currently there is only this one user report, and Postman has not yet issued a public response.
