Connect cubic to your IDE

Connect cubic’s MCP server to your coding agent so it can read PR review issues, use codebase wikis, inspect scan results, triage scan issues, and read team review learnings while you work.

Use the exact endpoint https://www.cubic.dev/api/mcp. Some OAuth clients reject https://cubic.dev/api/mcp because the protected resource origin does not match.

Open settings

Open Cursor Settings.

Open Tools and MCP

Go to Tools and MCP.

Choose MCP section

In MCP, use Home MCP Servers or your project-specific MCP section.

Create a server

Click New MCP server.

Save the config

Add this to the config and save:

"cubic": {
  "type": "http",
  "url": "https://www.cubic.dev/api/mcp"
}

Connect

Click Connect.

Add the MCP server

Add this to ~/.cursor/mcp.json or project .cursor/mcp.json:

{
  "mcpServers": {
    "cubic": {
      "type": "http",
      "url": "https://www.cubic.dev/api/mcp"
    }
  }
}

Run these commands from the project where you use Cursor Agent:

cursor-agent mcp enable cubic
cursor-agent mcp login cubic

Verify

cursor-agent mcp list-tools cubic

Add the MCP server

claude mcp add --transport http --scope user cubic https://www.cubic.dev/api/mcp

Open Claude Code and run:

/mcp

Choose cubic and complete the browser OAuth flow.

Verify

claude mcp list

Optional skills and slash commands

Install cubic’s Claude Code skills separately:

/plugin marketplace add mrge-io/skills
/plugin install cubic@cubic

Add the MCP server

codex mcp add cubic --url https://www.cubic.dev/api/mcp

codex mcp login cubic

Verify

codex mcp list

Add the MCP server

gemini mcp add --transport http --scope user cubic https://www.cubic.dev/api/mcp

Open Gemini CLI and run:

/mcp auth cubic

Verify

/mcp

Add the MCP server

Add this to ~/.config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "cubic": {
      "type": "remote",
      "url": "https://www.cubic.dev/api/mcp",
      "enabled": true
    }
  }
}

opencode mcp auth cubic

Verify

opencode mcp list

Add the MCP server

droid mcp add cubic https://www.cubic.dev/api/mcp --type http

Open Droid, run /mcp, choose cubic, and complete the browser OAuth flow.

Verify

The /mcp panel should show cubic as connected.

Install cubic's Pi target

npx @cubic-plugin/cubic-plugin install --to pi

The installer writes Pi’s MCP config to ~/.config/mcp/mcp.json.

Install the MCP adapter (if needed)

pi install npm:pi-mcp-adapter

Skip this step if pi-mcp-adapter is already installed.

Initialize and verify the MCP server

Run Pi’s guided setup:

pi-mcp-adapter init

Confirm the MCP config contains:

{
  "mcpServers": {
    "cubic": {
      "auth": "oauth",
      "url": "https://www.cubic.dev/api/mcp"
    }
  }
}

/mcp-auth cubic

Verify

/mcp reconnect cubic

Add the MCP server

Open the Command Palette, run MCP: Add Server, choose HTTP, and enter:

https://www.cubic.dev/api/mcp

Follow VS Code’s OAuth prompt for the cubic MCP server.

Verify

Run MCP: List Servers and confirm cubic is running.
