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.

Telnyx CLI for Coding Agents

Let coding agents discover schemas and execute integration functions through CLI commands or MCP.

Use this pattern when another coding agent needs exact commands and schema discovery. The Telnyx CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Telnyx CLI for Coding Agents
kosmokrator integrations:configure telnyx --set api_key="$TELNYX_API_KEY" --enable --read allow --write ask --json
kosmo integrations:call telnyx.telnyx_list_phone_numbers '{"page_size":1,"page_number":1,"filter_phone_number":"example_filter_phone_number","filter_status":"example_filter_status"}' --json

Discovery Before Execution

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

kosmo integrations:docs telnyx --json
kosmo integrations:docs telnyx.telnyx_list_phone_numbers --json
kosmo integrations:schema telnyx.telnyx_list_phone_numbers --json
kosmo integrations:search "Telnyx" --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.
