Open-source WhatsApp MCP server connects chat data to AI coding assistants

X postIshay TentserTool

Ishay Tentser has announced an MIT-licensed WhatsApp MCP server. The tool enables environments like Claude Code, Cursor, and Codex to connect to WhatsApp conversations via OAuth without requiring manual API key configuration.

Key points

  1. Provides 18 tools for querying and managing conversation data.
  2. Connects via OAuth, removing the need for manual API key handling.
  3. Compatible with Claude Code, Cursor, and Codex.
  4. Supports use cases such as identifying quiet leads and drafting follow-up messages.
  5. Released as open-source software under the MIT licence.

Why it matters

As the Model Context Protocol (MCP) expands, connecting core communication channels like WhatsApp directly to agentic coding tools allows developers to build and test automated sales or support interactions directly from their workflow.

Analysis

The release focuses on seamless onboarding and practical automation. By offering 18 discrete tools and eliminating API key management via OAuth, it provides coding assistants with direct, safe context to inspect messaging history and draft responses.

We shipped a WhatsApp MCP server. One command in Claude Code, sign in with OAuth, then just ask: "which leads went quiet for 5+ days? draft follow-ups, don't send." 18 tools. MIT licensed. No API keys to manage. Works in Cursor and Codex too.
