GREEN-API WhatsApp Skill\r

\r Use this skill when the user wants to send or receive WhatsApp messages, manage contacts, groups, or WhatsApp instances via GREEN-API.\r \r

Connection\r

\r Before using any tools, connect an instance with whatsapp_connect by providing instance_id and api_token (from console.green-api.com). This validates credentials and stores them for the session.\r \r Call whatsapp_disconnect when done.\r \r

Chat ID format\r

\r

Resources\r

\r

Important notes\r

\r

  • Always whatsapp_connect before calling any other tool.\r
  • Use whatsapp_check_whatsapp to verify a phone number has WhatsApp before sending.\r
  • For broadcasts, add delays between messages to avoid rate limiting.\r
  • File uploads use base64 encoding. Max file size: 100 MB.\r
  • Poll options must be unique, 2–12 items, max 100 chars each.\r
  • Message quoting only works within the same chat.\r
Usage Guidance
This skill appears to do what it says: integrate OpenClaw with GREEN-API. Before installing or using it, (1) confirm you trust green-api.com and the specific MCP URL you add to ~/.openclaw/openclaw.json; (2) only provide instance_id/api_token/partner_token when you understand how they are stored and how to revoke them — ask the skill author where session credentials are persisted and how to clear them; (3) be cautious when configuring webhook_url/webhook_url_token (these will send incoming messages/events to that endpoint); (4) rotate tokens if you test the skill with real credentials and remove the MCP entry when no longer needed. If you need higher assurance, request the author to declare required config paths in metadata and to document credential storage/retention explicitly.
Capability Analysis
Type: OpenClaw Skill Name: green-api Version: 1.0.0 The green-api skill is a legitimate integration for the GREEN-API WhatsApp service. It provides tools for messaging, instance management, and contact handling via an MCP gateway. The skill requires standard API credentials (instance_id and api_token) and communicates with official endpoints (green-api.com). No evidence of data exfiltration, malicious execution, or prompt injection was found.
Capability Assessment
Purpose & Capability
The skill is described as a GREEN-API WhatsApp integration and its tools (connect, send messages, manage groups, instance provisioning with partner_token) match that purpose. One small inconsistency: the README instructs adding an MCP server URL to the OpenClaw config (~/.openclaw/openclaw.json), but the skill metadata states no required config paths. Asking for instance_id/api_token/partner_token as tool params is expected for this purpose.
Instruction Scope
SKILL.md stays within the WhatsApp/GREEN-API domain: it instructs connecting an instance, using message/group/instance APIs, and optionally setting webhooks. Two items to flag for attention: (1) it says credentials are validated and "stored for the session" but does not specify storage location or retention — that should be clarified before trusting long-lived credentials; (2) the skill includes settings to configure webhook_url/webhook_url_token which, if set to arbitrary external endpoints, could forward incoming messages or events outside the user's control (this is a normal feature of webhook-capable integrations but is a data-exfiltration vector if misused).
Install Mechanism
Instruction-only skill with no install spec and no code files — lowest install risk. Nothing is downloaded or written by an automated installer as part of the skill package.
Credentials
No environment variables or system credentials are requested in the metadata. Credentials (instance_id, api_token, partner_token) are supplied as tool parameters, which is proportionate. The README's instruction to modify an OpenClaw config file is expected for adding an MCP server but is not declared in required config paths — a minor metadata omission.
Persistence & Privilege
The skill is not marked always:true and uses normal autonomous invocation. The only persistence implications in the docs are (a) adding an MCP server entry to the user's OpenClaw config (explicit setup step in README) and (b) unspecified session storage of credentials. Neither is inherently malicious, but you should confirm where credentials are persisted and how to remove them.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install green-api
  3. After installation, invoke the skill by name or use /green-api
  4. Provide required inputs per the skill's parameter spec and get structured output
