Can I use Lob as a CLI?

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

Can I expose Lob through MCP?

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

Where are Lob credentials stored?

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

Can I deny write access for Lob MCP tools?

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

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

Command Shape

# Lob CLI for Shell Scripts
kosmokrator integrations:configure lob --set api_key="$LOB_API_KEY" --enable --read allow --write ask --json
kosmo integrations:call lob.lob_list_letters '{"limit":1,"offset":1}' --json

Discovery Before Execution

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

kosmo integrations:docs lob --json
kosmo integrations:docs lob.lob_list_letters --json
kosmo integrations:schema lob.lob_list_letters --json
kosmo integrations:search "Lob" --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.
