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 Setup

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

# 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 use the same stored profile from scripts, coding CLIs, Lua code mode, and the MCP gateway.

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

Call LINE Messaging Headlessly

Use the generic call form when another coding CLI or script needs a stable universal interface.

kosmo integrations:call line.line_send_message '{
  "to": "example_to",
  "messages": "example_messages",
  "notification_disabled": true
}' --json

Use the provider shortcut form for shorter human-facing commands.

kosmo integrations:line line_send_message '{
  "to": "example_to",
  "messages": "example_messages",
  "notification_disabled": true
}' --json

Agent Discovery Commands

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

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

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.
