Postroom AI client compatibility
Which assistants work with Postroom today, which are awaiting directory review and which are unverified.
How to read this list
Confirmed working means a released listing or published plugin you can install. Custom connector means you add Postroom’s MCP endpoint yourself; it works but is not in that assistant’s directory. Pending directory review means an application is submitted; nothing is available yet. Unverified clients have not been tested by Postroom.
ChatGPT · Confirmed working
Postroom is released on ChatGPT. Connect your own workspace to prepare previews, approve schedules and track delivery.
Claude · Custom connector (works; not directory-listed)
Connect a custom remote connector to your authorized Postroom workspace. Follow the setup guide to authorize your own workspace.
Claude Code · Custom connector (works; not directory-listed)
Use Postroom from your terminal through scoped OAuth.
Hermes · Confirmed working
Postroom is available in the Hermes community plugin catalog. Connect your own workspace through OAuth.
OpenClaw · Confirmed working
Create an image and caption in OpenClaw, upload automatically, review the exact preview and approve scheduling. Connect your own workspace and publish to your eligible connected accounts. Image generation uses your configured image tool.
Gemini CLI · Custom connector (works; not directory-listed)
Follow the Antigravity migration guide to set up the terminal integration. This is separate from Google Gemini Connected Apps.
Google Gemini · Pending directory review
Postroom has applied for Google Connected Apps preview access. This does not yet make Postroom available in the Gemini app or Google Search.
Meta AI · Pending directory review
The Meta AI Connectors early-access application has been submitted. Access and public availability are pending.
Microsoft 365 Copilot · Planned
A Microsoft 365 Copilot integration is planned using the authenticated Postroom MCP server. There is no public install link yet.
Other MCP clients · Unverified
Clients such as Cursor, VS Code, Windsurf and Codex can connect to Streamable HTTP MCP servers with OAuth, but Postroom has not tested them. If you try one, use read-only access first and verify that a preview does not create a queue entry.
Every client follows the same rules
Assistants connect through scoped OAuth to your own workspace. They can prepare held previews; scheduling still needs your approval of the exact preview. Provider tokens never leave Postroom.
