Connect Svix 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.

Svix MCP Config for Claude Code

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

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

Run the Gateway Manually

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