Whether MCP can support grouping/namespace.

Scenario:
I have a complex system with many existing interfaces. These interfaces belong to different business domains.
For example, business A has 20 interfaces, business B has 30 interfaces, and business C has 50 interfaces.
I want to implement an MCP service to publish these interfaces through grouping.
For example, group_a would represent the 20 interfaces of business A, group_b would represent the 30 interfaces of business B, and group_c would represent the 50 interfaces of business C.
