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 Headless Automation

Use KosmoKrator as a non-interactive integration runtime for local automations and wrappers.

Use headless automation when another tool needs a stable local command surface. 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 Headless Automation
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.
