Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
EVOLUTION_API_URLRequired | Base URL of your Evolution API server, e.g. http://localhost:8080. Use https outside localhost. |
EVOLUTION_API_KEYRequired, secret | Evolution API key, sent as the apikey header. |
EVOLUTION_DEFAULT_INSTANCEOptional | Default instance used when a tool call omits the instance argument. |
EVOLUTION_TIMEOUT_MSOptional | Per-request timeout in milliseconds (default 30000). |
EVOLUTION_READ_ONLYOptional | Set to true to hide every tool that sends or changes state (send_text, send_media, create_instance, disconnect_instance, configure_webhook). |
EVOLUTION_CONFIRM_WRITESOptional | Set to true to require a human confirmation (elicitation dialog) before send_text, send_media, create_instance, disconnect_instance or configure_webhook run. Clients that can show no dialog are refused. Default false; an unrecognised value counts as true and prints a warning. |
EVOLUTION_ALLOWED_NUMBERSOptional | Comma-separated phone numbers that send_text and send_media may reach. Empty means no restriction. |
