Design rules
- Every response includes a disclaimer and
last_verifieddates. - Primary-source links (go.jp / e-Gov) are returned as-is — cite them in answers.
《…》is furigana for the preceding kanji; half-width spaces are wakachi-gaki word breaks (per the Immigration Services Agency × Agency for Cultural Affairs guideline).- yasashii.org is not a government website. If anything differs from an official page, the official page is correct.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
