Can I use Mailer Send as a CLI?

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

Can I expose Mailer Send through MCP?

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

Where are Mailer Send credentials stored?

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

Can I deny write access for Mailer Send MCP tools?

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

Mailer Send CLI for Shell Scripts

Call integration functions from shell scripts with stable JSON input and output.

Use shell scripts for small local automations that need one or more integration calls. The Mailer Send CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
