What problem does it solve?
WhatsApp Channel Capabilities enables agents to communicate with users via WhatsApp, including file sharing, media handling, and multi-agent coordination, all within the chat context.
Core Features & Use Cases
- Sending files: You can send files to the user using mcp__nanoclaw__send_file, save the file to your workspace (under /workspace/), and call the tool with the absolute path. Supported: images (jpg, png, gif, webp), videos (mp4, webm), audio (mp3, ogg, wav), documents (pdf, doc, txt, csv, json, zip). Maximum 64 MB.
- Receiving media: When users send images, voice notes, videos, or documents, they appear as [type: /workspace/group/media/filename] in the message. The file is available at that path for reading or processing.
- Reactions and Agent Teams: You can react to messages with emoji using mcp__nanoclaw__react; pass a sender parameter in mcp__nanoclaw__send_message to identify which agent is speaking, enabling bold prefixes like TARS: Research Specialist.
