Can I use Mailgun as a CLI?

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

Can I expose Mailgun through MCP?

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

Where are Mailgun credentials stored?

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

Can I deny write access for Mailgun MCP tools?

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

Mailgun CLI for Cron Jobs

Schedule repeatable integration workflows from cron while keeping credentials in KosmoKrator config.

Use the headless CLI from cron when an operation should run without an interactive agent session. The Mailgun CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Mailgun CLI for Cron Jobs
kosmokrator integrations:configure mailgun --set api_key="$MAILGUN_API_KEY" --set domain="$MAILGUN_DOMAIN" --enable --read allow --write ask --json
kosmo integrations:call mailgun.mailgun_get_current_user '{}' --json

kosmo integrations:docs mailgun.mailgun_get_current_user --json
kosmo integrations:schema mailgun.mailgun_get_current_user --json
kosmo integrations:search "Mailgun" --json

Automation Notes

Use --json for machine-readable output.

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.
