Who it is for
Someone organizing a group gathering in Japan who needs to collect availability from several people quickly.
Create shareable attendance polls for group events
Overview
OK Kanji, listed as OK幹事, is a group scheduling tool from Rocketa. Describing an event in the conversation, including its purpose, candidate dates, and start time, produces an attendance poll. The generated link is passed to invitees, who answer without signing up for anything.
Constraints can be stated in the same request, for example restricting options to weekdays or to a window of the next two weeks. Responses flow back into ChatGPT, where the poll shows which dates have drawn the most participants.
All dates and times are handled in Japan Standard Time.

Respondents need no account, and the running tally is readable from the same conversation that created the poll.
Availability
OK幹事 is listed in the ChatGPT apps directory only. Rocketa, Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from OK幹事's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Rocketa, Inc., and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
