Can I use Mailjet as a CLI?

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

Can I expose Mailjet through MCP?

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

Where are Mailjet credentials stored?

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

Can I deny write access for Mailjet MCP tools?

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

Mailjet MCP Gateway

Expose Mailjet to MCP clients with `kosmokrator mcp:serve --integration=mailjet`.

If the client has never used KosmoKrator before, install it first, then register this integration as a stdio MCP server. The gateway exposes only the selected integration in the example below.

curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

kosmokrator mcp:gateway:install --integration=mailjet --write=deny --json

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

Serve Manually
