The whatsapp_search_messages tool lets your AI assistant run an offline, full-text search across all of your WhatsApp chats directly on your Mac. It only reads locally-cached messages, so there is no network call and nothing leaves your machine. You just ask in plain English and the AI finds the thread you half-remember.

For example, type: "Search my WhatsApp for the apartment address my landlord sent me last month." The AI calls whatsapp_search_messages, scans every cached conversation, and surfaces the exact message with its sender and date — no scrolling through months of chats.

Download LMCP to give your AI assistant access to WhatsApp and 150+ other local Mac tools.

Which AI agents work?

LMCP works with every major MCP-capable assistant. Desktop clients auto-configure over local stdio; web AIs connect through the LMCP Cloud Relay connector.

  • Desktop (local stdio, auto-configured): Claude Desktop, Cursor, VS Code (GitHub Copilot), Windsurf and Zed.
  • Web (via LMCP Cloud Relay connector): ChatGPT, Claude.ai (web), Grok and Perplexity.

The same whatsapp_search_messages tool is exposed to all of them, so your search experience is identical no matter which assistant you prefer.

Automation

Search is most powerful when it chains with other tools. Because LMCP exposes 150+ tools to one assistant, you can stitch workflows together in a single prompt:

  • Find a WhatsApp message about a meeting, then create a Calendar event from the details.
  • Search a chat for a phone number or address and save it straight to Contacts.
  • Pull a discussion thread from WhatsApp and draft a follow-up email summarizing the decision.
  • Locate a forwarded link and add it to Reminders or Notes for later.

The AI orchestrates these steps for you — search becomes the entry point to real action, not just a lookup.

Context

Unlike a generic chatbot, your assistant is working with your actual WhatsApp history on your Mac. It reads the real cached messages, the real names, and the real timestamps. That means answers are grounded in your conversations instead of guesses, and the AI can reason about who said what and when across every chat you have.

Productivity

Manually searching WhatsApp means switching apps, scrolling endlessly, and trying to remember exact wording. With whatsapp_search_messages, you describe what you're looking for and get the answer in seconds — without leaving your AI conversation. Finding a shared address, an order confirmation, a quoted price, or a date someone mentioned drops from minutes of digging to a single sentence. Over a busy week that adds up to real time back.

Privacy & GDPR

Everything runs locally on your Mac. The search reads only your locally-cached WhatsApp messages, never sends them to a server, and stores nothing in the cloud. There are no API keys and no third-party data processors involved. This local-first design makes LMCP GDPR-compliant by architecture — your messages stay on your machine, fully under your control.
