Getting to know Bison.

What is Bison?

Bison is a native MongoDB client for macOS. It brings document browsing and editing, queries, aggregation pipelines, dashboards, and permissioned AI agent access into one Mac app.

Which Macs does Bison support?

Bison requires macOS 15 or later and supports both Apple silicon and Intel Macs. It is built with SwiftUI and AppKit, with support for light and dark appearances, keyboard navigation, and VoiceOver.

Can I connect to MongoDB Atlas or use SSH?

Yes. Connect with a mongodb:// or mongodb+srv:// URI, or use the connection form. Bison supports MongoDB Atlas, SCRAM authentication, custom TLS settings, and built-in SSH tunnels with password or key authentication.

Do I need to use AI to use Bison?

No. All database browsing, editing, queries, pipelines, and dashboards work independently of AI. Agent access is optional and controlled separately for each connection.

How does access for AI agents work?

Bison includes an MCP server for clients such as Claude Code, Claude Desktop, and Cursor. You set the access level for each connection, limit which databases are available, redact fields, and review write requests. Agent requests are recorded in an audit log. Data you allow an agent to read is subject to that agent provider’s data policies.

When can I download it, and what will it cost?

Bison will cost $29.99 USD as a one-time purchase. No subscription. It is still in development, with early access planned through the Mac App Store. A release date has not been announced yet.

A better place for your data.
