Where Gemini CLI stands · on 2026-06-18 Google ended the consumer
service (AI Pro, Ultra and free tiers) in favor of
Antigravity CLI ·
enterprise access and paid API keys continue, and the
OSS repo stays active. This
guide remains valid for those paths; an Antigravity guide follows once our
wiring is live-proven.
mcpServers in its user-scope ~/.gemini/settings.json. The binary
comes first: brew install supernovae-st/tap/nika
(other paths).
Add the nika entry to ~/.gemini/settings.json:
nika wire gemini writes exactly this · it touches only the mcpServers
key, so every other setting in the shared file survives, and re-running
prints · current (idempotent).
Gemini CLI’s policy parser splits server names on underscores — a server
named
my_server misbehaves upstream. nika is underscore-free, safe
as-is.The repo side
nika init writes the agent-teaching surface (AGENTS.md, rules) plus
the $schema modeline for validation and completion on *.nika.
Verify
/mcp in a Gemini CLI session lists nika with the nine nika_* tools
(the oracle’s contract: validate, explain, schema,
cost — no execution). Then prove the loop end-to-end:
integrate in 10 minutes.
