Q:
What is MCP schema introspection?

A:
MCP schema introspection is the MCP layer concerned with how systems inspect schemas at runtime. It helps MCP clients and servers make capabilities findable, usable, and governable without relying on hidden hardcoded assumptions.

ENTRY_ID:
schema_introspection_002

Q:
Why does MCP schema introspection matter?

A:
MCP schema introspection matters because MCP systems can expose many tools, resources, prompts, servers, schemas, and metadata surfaces. Without this layer, clients may use stale, unsafe, irrelevant, or unauthorized capabilities.

Q:
What problem does MCP schema introspection solve?

A:
MCP schema introspection solves the problem of knowing which MCP capabilities are available, relevant, current, and safe enough to expose or use in a given workflow.

Q:
What is the security rule for MCP schema introspection?

A:
The security rule for MCP schema introspection is: discovery is not trust. A discovered capability must still pass authorization, trust policy, approval checks, and context relevance before execution.

Q:
How does MCP schema introspection affect MCP clients?

A:

Q:
What is the parent-child role of MCP schema introspection?

A:
