Every MCP-capable client wires the same read-only oracle (what it exposes) with the same two fields — command: nika · args: [mcp]. The binary comes first: brew install supernovae-st/tap/nika (other paths). This page is the matrix; every client has a dedicated page with the exact file, shape, reload behavior and verify step. One-click where the client supports it (binary still required first): Install in VS Code Install MCP Server And in every case, nika init first — the agent-teaching surface (AGENTS.md, rules, the repo skill) is what makes the oracle useful.

​
The client matrix

The anchors below stay for directory deep-links — each points to its dedicated page.

​
Cursor

nika wire cursor → ~/.cursor/mcp.json, plus the one-click deeplink and the auto-attached .cursor/rules/nika.mdc — full page.

​
Claude Code

nika wire claude → ~/.claude.json, plus the first-party plugin (claude plugin install nika@nika) — full page.

​
Codex

nika wire codex → ~/.codex/config.toml (comments preserved), plus the plugin — full page.

​
VS Code / Copilot

nika wire vscode → repo-local .vscode/mcp.json, plus the marketplace extension — full page.

​
Zed

nika wire zed → context_servers in ~/.config/zed/settings.json, with the JSONC-respecting contract — full page.

​
Gemini CLI

The mcpServers stanza in ~/.gemini/settings.json (wire lands next release) — full page.

​
Windsurf

nika wire windsurf → ~/.codeium/windsurf/mcp_config.json — full page.

​
OpenCode

Native AGENTS.md + repo-skill discovery — see the dedicated OpenCode page.

​
Hermes

Tap-installable delegation skill + mcp_servers stanza — see the dedicated Hermes page.

​
Continue

An own-file drop: ~/.continue/mcpServers/nika.json — reload to pick it up — full page.

​
Cline

cline_mcp_settings.json (hot-reloaded; the file’s two possible homes resolved) — full page.

​
LM Studio

Cursor-notation mcp.json, with the real macOS path quirk — full page.

​
goose

A stdio extension stanza + native AGENTS.md reading — full page.

​
Aider

Aider reads repo conventions rather than MCP: nika init’s AGENTS.md covers it (add CONVENTIONS.md: AGENTS.md to .aider.conf.yml if you keep conventions elsewhere). The check loop is the same: nika check <file> after every edit.

​
Verify (any client)

Ask the agent to list its tools — the nine nika_* names should appear. Then prove the loop end-to-end: integrate in 10 minutes.
Client config formats move fast. The stable contract is the stanza (nika + mcp) and the oracle’s read-only surface — if a client’s documented path has moved, the stanza still applies.
