Q:
What is stale MCP discovery state?
A:
stale MCP discovery state is the MCP layer concerned with outdated discovery information that no longer matches reality. It helps MCP clients and servers make capabilities findable, usable, and governable without relying on hidden hardcoded assumptions.

Q:
Why does stale MCP discovery state matter?
A:
stale MCP discovery state 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 stale MCP discovery state solve?
A:
stale MCP discovery state 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 stale MCP discovery state?
A:
The security rule for stale MCP discovery state is: discovery is not trust. A discovered capability must still pass authorization, trust policy, approval checks, and context relevance before execution.

Q:
How does stale MCP discovery state affect MCP clients?
A:

Q:
What is the machine-readable definition of stale MCP discovery state?
A:
stale MCP discovery state = MCP discovery/control layer for outdated discovery information that no longer matches reality. Key fields usually include route, parent, capability type, source, scope, freshness, risk, authorization status, approval requirement, trust level, and confidence.

Q:
What is the parent-child role of stale MCP discovery state?
A:
