Overview

An MCP server for WhatsApp enabling message retrieval, contact search, and message sending via the WhatsApp web API, storing data locally in SQLite.

This server offers convenient access to WhatsApp data but requires careful management of tool permissions to mitigate the risk of unintended actions or data exfiltration. It is safer for read-only operations but becomes riskier when message sending and file operations are enabled. Regular security audits and monitoring are recommended.

Performance depends on the size of the WhatsApp message history and the efficiency of the SQLite database queries. Large message histories may result in slower search and retrieval times.

The primary cost consideration is the computational resources required to run the Go bridge and Python server. There are no direct API costs associated with WhatsApp.

Positive

+Message data is stored locally in a SQLite database.
+Access to WhatsApp data is mediated through MCP tools.
+User retains control over which tools the agent can access.
+No external accounts or services are directly exposed.

Risks

-Subject to project injection leading to data exfiltration.
-Requires access to a personal WhatsApp account.
-Has tools to send messages and files, potentially leading to unintended actions.
-Stores message history locally, posing a risk if the system is compromised.
-Relies on third-party libraries (whatsmeow) for WhatsApp API interaction.

Use Cases

Information Retrieval

-Searching for specific messages or contacts.
-Summarizing past conversations.
-Finding information shared in media files.

Communication Automation

-Sending automated reminders or updates.
-Responding to common inquiries.
-Forwarding relevant information to contacts.

Data Analysis

-Analyzing communication patterns.
-Identifying key topics discussed in chats.
-Extracting insights from message content.

Content Management

-Downloading and organizing media files.
-Archiving important conversations.
-Creating backups of message history.

Who Is This For?

Best For

Users who want to access and analyze their WhatsApp data.
Automating simple communication tasks.
Integrating WhatsApp with other applications or services.
Developers who want to build custom WhatsApp integrations.

Not Ideal For

Handling highly sensitive or confidential information.
Applications requiring real-time message processing.
High-volume message sending or automated spamming.

Autonomy & Execution

Default ModeRead and Write enabled

The agent's autonomy depends on the configured tool access. Granting access to send_message and send_file tools enables the agent to initiate actions without explicit user confirmation.

StatelessNo

Retry LogicNot documented

ConcurrencySingle-threaded

Production Tip

Implement robust error handling and logging to monitor the server's behavior and identify potential issues in a production environment.

FAQ

How often do I need to re-authenticate?

You will need to re-authenticate approximately every 20 days by scanning a new QR code.

What happens if I reach the device limit on WhatsApp?

You'll need to remove an existing device from WhatsApp on your phone (Settings > Linked Devices).

Why are my messages not loading after authentication?

It can take several minutes for your message history to load, especially if you have many chats.

What should I do if my WhatsApp messages get out of sync?

Delete both database files (`whatsapp-bridge/store/messages.db` and `whatsapp-bridge/store/whatsapp.db`) and restart the bridge to re-authenticate.

Do I need FFmpeg?

FFmpeg is only needed if you want to send audio files as playable WhatsApp voice messages and the audio files are not already in `.ogg` Opus format.

Is my data secure?

Your messages are stored locally in a SQLite database. Ensure your system is secure to protect this data. Be cautious of project injection risks.

Can I use this with multiple WhatsApp accounts?

No, this is designed to connect to a single personal WhatsApp account at a time.
