LINE Messaging MCP Gateway

Expose LINE Messaging to MCP clients with `kosmokrator mcp:serve --integration=line`.

If the client has never used KosmoKrator before, install it first, then register this integration as a stdio MCP server. The gateway exposes only the selected integration in the example below. 

curl -fsSL https://raw.githubusercontent.com/OpenCompanyApp/kosmokrator/main/install.sh | bash
kosmokrator mcp:gateway:install --integration=line --write=deny --json
{
  "mcpServers": {
    "kosmokrator-line": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=line",
        "--write=deny"
      ]
    }
  }
}

Serve Manually
