notation. The safe path is in-app — Program tab →
Install > Edit mcp.json — then add:
brew install supernovae-st/tap/nika
(other paths).
Where the file lives
LM Studio documents~/.lmstudio/mcp.json (macOS + Linux;
%USERPROFILE%\.lmstudio on Windows) — but on some macOS installs the app
actually keeps it under ~/.cache/lm-studio/ instead
(lmstudio-bug-tracker#1371, open). Writing the documented path there wires
nothing, which is why editing in-app is the safe manual route.
nika wire lmstudio ships in the next release and resolves this for you:
whichever app-created directory exists wins (documented location first);
neither existing falls back to the documented default. Idempotent,
unrelated servers preserved.

LM Studio’s MCP listing showsnika with the nine nika_* tools
(the oracle’s contract: validate, explain, schema,
cost — no execution, no mutation). A fully local pairing: LM Studio serves
the model, Nika runs the workflow —
