Can I use LINE Messaging as a CLI?

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

Can I expose LINE Messaging through MCP?

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

Where are LINE Messaging credentials stored?

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

Can I deny write access for LINE Messaging MCP tools?

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

LINE Messaging CLI for AI Agents

Use the LINE Messaging CLI from KosmoKrator to call LINE Messaging tools headlessly, return JSON, inspect schemas, and automate workflows from coding agents, scripts, and CI.

LINE Messaging CLI Setup

LINE Messaging can be configured headlessly with `kosmokrator integrations:configure line`.

Install, configure, and verify

# Install KosmoKrator first if it is not available on PATH.
curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash

# Configure and verify this integration.
kosmokrator integrations:configure line --set access_token="$LINE_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmokrator integrations:doctor line --json
kosmokrator integrations:status --json

Credentials

Authentication type: Bearer token bearer_token. Configure credentials once, then reuse the same stored profile from scripts, coding CLIs, Lua, and MCP.

Key	Env var	Type	Required	Label
`access_token`	`LINE_ACCESS_TOKEN`	Secret `secret`	yes	Channel Access Token
`url`	`LINE_URL`	URL `url`	no	API Base URL

Command Patterns

The generic command is stable across every integration. The provider shortcut is shorter for humans.

Generic CLI call

kosmo integrations:call line.line_reply_message '{"reply_token":"example_reply_token","messages":"example_messages","notification_disabled":true}' --json

Provider shortcut

kosmo integrations:line line_reply_message '{"reply_token":"example_reply_token","messages":"example_messages","notification_disabled":true}' --json

Discovery

These commands return structured output for coding agents that need to inspect capabilities before choosing a function.

Discovery commands

kosmo integrations:docs line --json
kosmo integrations:docs line.line_reply_message --json
kosmo integrations:schema line.line_reply_message --json
kosmo integrations:search "LINE Messaging" --json
kosmo integrations:list --json

Automation Contexts

The same configured command surface works in these environments. The command does not change unless the host wrapper, credentials, or permissions change.

CI Run integration calls from CI jobs with JSON output, explicit credentials, and predictable exit status. Cron Jobs Schedule repeatable integration workflows from cron while keeping credentials in KosmoKrator config. Shell Scripts Call integration functions from shell scripts with stable JSON input and output. Headless Automation Use KosmoKrator as a non-interactive integration runtime for local automations and wrappers. Coding Agents Let coding agents discover schemas and execute integration functions through CLI commands or MCP.

Permissions

Headless calls still follow the integration read/write permission policy. Configure read/write defaults with integrations:configure. Add --force only for trusted automation that should bypass that policy.
