A [Catalyst Dynamic MCP Server](https://docs.catalyst.zoho.com/en/ai-toolkit/catalyst-mcp-server/overview/#catalyst-dynamic-mcp-server) dynamically loads only the tools required to fulfill your prompt, querying its directory at the time of invocation. This means you do not need to manually configure tools beforehand, and all 100+ Catalyst MCP tools remain accessible without hitting LLM tool limits. A [Catalyst Custom MCP Server](https://docs.catalyst.zoho.com/en/ai-toolkit/catalyst-mcp-server/overview/#catalyst-custom-mcp-server), on the other hand, requires you to manually select and configure the exact tools you need via the [MCP console](https://mcp.zoho.in/). Use a Custom MCP server when you have a well-defined, predictable set of operations.
