Use Nika with Claude Desktop - Nika

Claude Desktop is a different app with a different config file than Claude Code’s ~/.claude.json — it reads claude_desktop_config.json from the platform app-config dir. The binary comes first: brew install supernovae-st/tap/nika (other paths). Add the nika server under mcpServers:

{ "mcpServers": { "nika": { "command": "nika", "args": ["mcp"] } } }

The file lives at:

Platform	Path
macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Windows	`%APPDATA%\Claude\claude_desktop_config.json`
Linux	`~/.config/Claude/claude_desktop_config.json` (community builds — same dir the app uses)

nika wire claude-desktop ships in the next release and writes exactly this — idempotent, every unrelated server preserved.

Each engine release also ships one-click .mcpb bundles (macOS arm64 · Linux x64, with checksums) if you prefer not to touch JSON at all.

Verify

Restart Claude Desktop, then check its tools list — the nine nika_* tools appear (the oracle’s contract: validate, explain, schema, cost — no execution, no mutation). The config-file convention is the MCP quickstart’s own (modelcontextprotocol.io). Then prove the loop end-to-end: integrate in 10 minutes.
