README
# wa-chat-reader <!-- mcp-name: io.github.NabheetCloud/wa-chat-reader --> **Unofficial, read-only [MCP](https://modelcontextprotocol.io) server for your local WhatsApp chat history.** `wa-chat-reader` reads the WhatsApp `ChatStorage.sqlite` database that the WhatsApp desktop app keeps on your machine and exposes two tools to any MCP client (Claude Code, Claude Desktop, etc.) so you can summarize, search, and reason over your own messages. Everything runs locally — **no data ever leaves your computer.** > ⚠️ **Not affiliated with, endorsed by, or connected to WhatsApp or Meta.** > "WhatsApp" is a trademark of Meta Platforms, Inc. This is an independent, > unofficial tool that only reads a database WhatsApp already stores on your device. --- ## Privacy & security This tool touches highly sensitive data — your private conversations. Read this first. - **Read-only.** The database is opened with SQLite `mode=ro&immutable=1`; the server never writes to, modifies, or deletes anything. - **Local-only.** There is no network code. Messages are returned to your MCP client and nowhere else. Whatever LLM/client you connect will, of course, see the message text you ask it to read — you control that by choosing which client to run. - **Your consent, your data.** Only run this against your own device and your own chats. Do not use it to access anyone else's messages. - **macOS access.** The WhatsApp database lives in a protected group container. The process running this server needs **Full Disk Access** (System Settings → Privacy & Security → Full Disk Access), or point `WHATSAPP_DB_PATHS` at a readable copy you export yourself. - **Scope control.** `WHATSAPP_MAX_DAYS` (default 30) caps how far back any single call can read. --- ## Install Requires Python ≥ 3.10. Recommended: [`uv`](https://docs.astral.sh/uv/) so the server runs in an isolated environment. ```bash # one-shot run (no install) uvx wa-chat-reader # or install with pip pip install wa-chat-reader wa-chat-reader ``` ## Use in Claude Code ```bash claude mcp add wa-chat-reader -- uvx wa-chat-reader ``` Or install as a plugin (see the marketplace section below), then ask Claude things like: - "Summarize my unread WhatsApp group chats from the last 3 days." - "List the WhatsApp chats I've been active in this week." ## Configuration All configuration is via environment variables (all optional): | Variable | Default | Description | |---|---|---| | `WHATSAPP_DB_PATHS` | platform default | `;`-separated candidate paths to `ChatStorage.sqlite` (first readable wins) | | `WHATSAPP_BACKUP_PATHS` | — | `;`-separated fallback paths, tried after the primary paths | | `WHATSAPP_MAX_DAYS` | `30` | Max look-back window (days) a caller may request | | `WHATSAPP_DEBUG` | `false` | `true` for verbose logging to stderr | | `WHATSAPP_LOG_FILE` | — | Optional path to also write logs to a file | Default database locations: | OS | Path | |---|---| | macOS | `~/Library/Group Containers/group.net.whatsapp.WhatsApp.shared/ChatStorage.sqlite` | | Windows | `~/AppData/Roaming/WhatsApp/Databases/ChatStorage.sqlite` | | Linux | `~/.local/share/whatsapp/ChatStorage.sqlite` | ## Tools | Tool | Description | |---|---| | `get_whatsapp_messages` | Concatenated message text from group and personal chats within a look-back window. Params: `days` (1–max), `chat_type` (`all`/`groups`/`personal`). Read-only. | | `get_whatsapp_chat_list` | Active chat names (no message bodies) within a look-back window. Param: `days`. Read-only. | Both tools are annotated `readOnlyHint: true`. ## Bonus: activity dashboard `whatsapp_dashboard.py` renders a self-contained, offline HTML dashboard of your messaging activity (volume over time, daily/weekly rhythm, top chats) straight from the same database: ```bash python3 whatsapp_dashboard.py # -> whatsapp_dashboard.html ``` The generated HTML contains real contact names — it is git-ignored and meant to stay local. ## Develop ```bash git clone https://github.com/NabheetCloud/wa-chat-reader cd wa-chat-reader pip install -e . python3 simple_whatsapp_mcp.py # run from source without installing ``` ## License [MIT](./LICENSE) © 2026 Nabheet Madan
