Frequently Asked Questions

What is Whatsapp MCP?

An MCP server for searching your personal WhatsApp messages, contacts and sending messages to individuals or groups

What tools does Whatsapp MCP provide?

Whatsapp MCP provides 12 tools including search_contacts, list_messages, list_chats, get_chat. Each tool can be called by AI agents to perform specific operations.

Is Whatsapp MCP safe to use?

We cannot tell you that, and nobody scanning at this scale can. What we did in March 2026 was shallow-clone Whatsapp MCP and run five keyword searches over its source: auth identifiers, CORS configuration, rate-limit identifiers, the dependency manifest against a hardcoded list of 18 known-vulnerable packages, and unguarded eval/exec calls. At least one matched — the specific finding is in the scan report on this page. A text search cannot follow a variable, judge intent, or tell you what a server does once it is running, so "nothing matched" is not "safe". What the scan does and does not cover is written out at /mcp/security.
