Can I use Cal.com as a CLI?

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

Can I expose Cal.com through MCP?

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

Where are Cal.com credentials stored?

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

Can I deny write access for Cal.com MCP tools?

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

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

Command Shape

# Cal.com CLI for Headless Automation
kosmokrator integrations:configure cal --set access_token="$CAL_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call cal.cal_list_event_types '{"limit":1,"page":1,"teamId":1}' --json

Discovery Before Execution

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

kosmo integrations:docs cal --json
kosmo integrations:docs cal.cal_list_event_types --json
kosmo integrations:schema cal.cal_list_event_types --json
kosmo integrations:search "Cal.com" --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.
