Can I use Microsoft Outlook as a CLI?

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

Can I expose Microsoft Outlook through MCP?

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

Where are Microsoft Outlook credentials stored?

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

Can I deny write access for Microsoft Outlook MCP tools?

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

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

Command Shape

# Microsoft Outlook CLI for Headless Automation
kosmokrator integrations:configure microsoft-outlook --set access_token="$MICROSOFT_OUTLOOK_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call microsoft-outlook.outlook_list_messages '{"top":1,"filter":"example_filter","orderby":"example_orderby","select":"example_select","skip":1}' --json

Discovery Before Execution

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

kosmo integrations:docs microsoft-outlook --json
kosmo integrations:docs microsoft-outlook.outlook_list_messages --json
kosmo integrations:schema microsoft-outlook.outlook_list_messages --json
kosmo integrations:search "Microsoft Outlook" --json
kosmo integrations:list --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.
