Kerno MCP (Claude Code + Cursor + Codex plugin)

Markdown-only plugin: slash commands, skills, and rules that guide use of the Kerno MCP tools. The agent runtime is not included here — install and start it with @kerno/cli.

Source: github.com/kernoio/kerno-mcp-plugin

Give this repo to your coding tool

Quick install (Skills CLI)

From your project root (or use -g for a user-wide install), install the plugin skills into the agents the CLI detects (Cursor, Claude Code, Codex, and others):

npx skills add kernoio/kerno-mcp-plugin

Then run /install-kerno (or @install-kerno in Codex) in that workspace to install @kerno/cli, start the agent with kerno mcp -w, and register MCP.

To refresh after upstream changes:

npx skills update kernoio/kerno-mcp-plugin

Useful flags: -g / --global, -a cursor (or claude-code, codex, …), -y to skip prompts. See vercel-labs/skills.

Marketplace install is not available yet — use the GitHub repo directly (npx skills add or clone). This path installs skills (procedures). Slash commands, Cursor rules, and full plugin manifests still use the per-client install steps below if you need them.

Or: paste a prompt into your assistant

Paste one prompt below into your assistant (Agent chat, Claude Code, Codex, etc.). It installs skills from the GitHub repo, then runs install-kerno to install the CLI, start the agent, and connect MCP for your workspace. Do not use plugin marketplaces.

Tool	Copy-paste prompt
Claude Code	prompts/install-claude.md
Cursor	prompts/install-cursor.md
Codex	prompts/install-codex.md

Claude Code

Install and set up Kerno MCP for this workspace using https://github.com/kernoio/kerno-mcp-plugin.

Do not use any plugin marketplace — Kerno is not published to marketplaces yet.

1. Run `npx skills add kernoio/kerno-mcp-plugin -y` from the project root to install Kerno skills on this machine.
   For slash commands too: clone the repo to ~/.kerno/mcp-plugin and restart Claude with `claude --plugin-dir ~/.kerno/mcp-plugin` (see claude/README.md). Do not use `/plugin marketplace`.
2. Run the install-kerno skill (/install-kerno) to install @kerno/cli, log in, start the agent with kerno mcp -w on this project, and register MCP.
3. Verify kerno_get_applications works for this workspace path.

Work in this repository root unless I specify another path.

Cursor

Open in Cursor: use the link under the prompt block, or copy the text below.

Install and set up Kerno MCP for this project using https://github.com/kernoio/kerno-mcp-plugin.

Do not use any plugin marketplace — Kerno is not published to marketplaces yet.

1. Run `npx skills add kernoio/kerno-mcp-plugin -y` from the project root to install Kerno skills.
   For slash commands, rules, and full plugin: clone to ~/.kerno/mcp-plugin and symlink into ~/.cursor/plugins/local/kerno, then reload Cursor (see cursor/README.md).
2. Run /install-kerno to install @kerno/cli, bind the agent to this workspace with kerno mcp -w, and register MCP with the URL from CLI output.
3. Confirm Kerno MCP tools are available in this project folder.

Work in this repository root unless I specify another path.
