Which Catalyst MCP Server should I use, Dynamic or Custom?

Neither server is inherently better than the other. Each is designed for a specific use case, and the right choice depends on the nature of your operation.

The Catalyst Dynamic MCP Server is best suited for exploratory or dynamic workflows where the full scope of required tools is not known in advance. It automatically identifies and loads only the tools needed for your prompt, giving your LLM access to all 100+ Catalyst MCP tools without manual configuration or the risk of tool overload causing hallucinations.

The Catalyst Custom MCP Server is best suited for targeted, well-defined operations where you know exactly which tools are required. By configuring only the necessary tools upfront via the MCP console, you keep the server lean, predictable, and optimized for that specific workflow.

In short, use the Dynamic MCP Server when you need flexibility and broad coverage. Use the Custom MCP Server when you need precision and control. Evaluate your use case first, and let that guide your choice.
