Use this page for assistants without a native Cekura plugin. The generic pattern is the same: install Cekura guidance, then connect MCP if your assistant supports it. Gemini CLI is an exception — it has a native extension, covered at the end.

Choose the right path

PathUse whenResult
Agent Skills + MCPYour assistant supports Agent Skills and MCPBest non-Claude-Code setup
Behavior preset + MCPYour assistant supports rules/context files and MCPGood fallback when Agent Skills are not loaded automatically
Behavior preset onlyYour assistant has no MCP supportCekura guidance without live workspace actions
MCP onlyYou only want direct Cekura toolsAPI access without Cekura workflow guidance

​
Install Cekura guidance

Try Agent Skills first: 
npx skills add cekura-ai/cekura-skills --all
If your assistant does not load Agent Skills, install the portable behavior preset wherever your assistant reads project rules or agent instructions: 
curl -L https://raw.githubusercontent.com/cekura-ai/cekura-skills/main/codex/AGENTS.md -o AGENTS.md
For assistants with a dedicated rules directory, place the file there instead.

​
Connect MCP

If your assistant supports HTTP MCP, use: 
https://api.cekura.ai/mcp
If your assistant requires a local command shim, use mcp-remote: 
{
  "mcpServers": {
    "cekura": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.cekura.ai/mcp"]
    }
  }
}
For client-specific OAuth and API-key examples, see manual setup.

​
Verify setup

Ask your assistant: 
Use the Cekura skills and MCP. List my Cekura agents, pick one, and propose 3 evaluators I should create first. Do not create anything until I approve.
If the assistant cannot list agents, MCP is not connected. If it lists agents but gives generic testing advice, add the behavior preset or confirm Agent Skills are enabled.

​
Gemini CLI

Gemini CLI has a native Cekura extension that includes the MCP server and the Cekura context file. (Gemini extensions don’t bundle Agent Skills yet, so this ships domain knowledge as context rather than SKILL.md skills.) 
gemini extensions install https://github.com/cekura-ai/cekura-skills
On first use of a Cekura MCP tool, Gemini runs an OAuth browser sign-in — no API key. The extension loads GEMINI.md (metric design, eval design, API reference, anti-patterns) as context. Update it with: 
gemini extensions update cekura

​
When to use Claude Code instead

Use Claude Code if you want the full Cekura plugin experience: Skills, slash commands, MCP auto-configuration, update support, and MCP failure help.
