Postmark 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 Postmark CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Postmark CLI for Shell Scripts
kosmokrator integrations:configure postmark --set server_token="$POSTMARK_SERVER_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call postmark.postmark_list_messages '{"count":1,"offset":1,"recipient":"example_recipient","fromemail":"example_fromemail","subject":"example_subject","status":"example_status","tag":"example_tag"}' --json

Discovery Before Execution

Agents and scripts can inspect Postmark docs and schemas before choosing a function.

kosmo integrations:docs postmark --json
kosmo integrations:docs postmark.postmark_list_messages --json
kosmo integrations:schema postmark.postmark_list_messages --json
kosmo integrations:search "Postmark" --json
kosmo integrations:list --json

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.
