Frequently asked questions
How is write protection enforced?
The server is designed as read-only by design, and includes safety validation that prevents write operations in aggregation pipelines.
What are the runtime requirements?
Node.js for building and running, network access to the MongoDB server, and appropriate read permissions on target databases.
How do I debug the server?
Use the MCP Inspector by running `npm run inspector`, which provides a URL for debugging tools.
Is authentication supported?
Yes, authentication credentials can be included in the `MONGODB_URI` connection string. It is recommended to use a MongoDB user with read-only permissions.
