Postbot is an MCP server published by postbot.cz. Marketplaces we read that list it: 1 (Official MCP Registry). The last change we recorded was on 2026-10-15. As of our marketplace pass on 2026-11-04.

What it asks for

  • Runs remotely
  • Secrets: 1
  • Settings: 9

Requires: POSTBOT_CP_PASSWD (secret), POSTBOT_CP_USER, POSTBOT_TEST

Only install plugins from developers you trust. We list what marketplaces publish and do not test plugins.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.

Want this mark on your plugin in our catalog?

Prove you maintain it with a file in its repository, a file on your domain or a DNS record, and you can show this mark on the card, with live banners for your site and README. How verification works

You also get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
