Can I use Bubble as a CLI?

Yes. KosmoKrator exposes a Bubble CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Bubble through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Bubble tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Bubble credentials stored?

Bubble credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Bubble MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Connect Bubble to Claude Code

Connect local KosmoKrator integrations to Claude Code through one scoped MCP gateway entry.

Add KosmoKrator as a stdio MCP server in the Claude Code project config and select the integrations that should be visible. The gateway is local, scoped to this integration, and starts with --write=deny so Claude Code can inspect read-capable tools without receiving write access by default.

Bubble MCP Config for Claude Code

Claude Code can launch the local kosmo binary directly from the project MCP config.

{
  "mcpServers": {
    "kosmokrator-bubble": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=bubble",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=bubble --write=deny

Why Use KosmoKrator Here
