Specials

Thanks to a certain connection, this is my third year as a member of the Virtual Reality Society of Japan. It is also my third time attending the general meeting and networking event. In the first year, I understood so little that I did nothing, but in the second year I had planned to attend the annual conference. In the end, my schedule did not work out, so in the second year too I only attended the general meeting and networking event. The booklet they send is interesting, and I look forward to every issue.

On Thursday, March 19, Codex Meetup Tokyo #1 was held in a space inside the Mercari office at Roppongi Hills. I also gave an LT titled "Maximizing XR Exploration and Learning by Continuing to Build MCP / Skills for visionOS Development." Thank you to everyone who attended. This time I will write about the materials and some supplementary content.

This is really just a small update, but I added a tool called inspect_xcode_schemes. It improves cases where relying on Codex to specify a scheme nicely would sometimes result in errors because the scheme could not be found.

One week after v0.1.0, which I released last week, I decided to release the next version. When I first started building Seiro MCP, I began from the idea that it would be enough to build only the minimum required pieces. But as I built it, I found new discoveries and came up with new ideas, and the things I wanted to do increased. There is still more to do.

On February 18, 2026, Seiro MCP finally reached version 0.1.0. At first I had so little confidence that I started from 0.0.1. The major topics this time are Skills support and added diagnostic functionality around SDKs. I am a heavy user of Seiro MCP to the point that I use it every day, so I decided that if I am using it this much myself, it is fair to call it 0.1.0. Incidentally, I also added a logo.
