Can I use Telnyx as a CLI?

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

Can I expose Telnyx through MCP?

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

Where are Telnyx credentials stored?

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

Can I deny write access for Telnyx MCP tools?

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