Q:
What is MCP server refresh?
A:
MCP server refresh is the MCP layer concerned with refreshing server identity, trust, version, and capabilities. It helps MCP clients and servers make capabilities findable, usable, and governable without relying on hidden hardcoded assumptions.

Q:
Why does MCP server refresh matter?
A:
MCP server refresh 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 server refresh solve?
A:
MCP server refresh 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 server refresh?
A:
The security rule for MCP server refresh 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 server refresh affect MCP clients?
A:
MCP server refresh helps MCP clients decide what to load, what to hide, what to refresh, what to ask approval for, and what to keep out of model context.

Q:
What is the machine-readable definition of MCP server refresh?
A:
MCP server refresh = MCP discovery/control layer for refreshing server identity, trust, version, and capabilities. 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 MCP server refresh?
A:
MCP server refresh sits under /ai/agents/tools/mcp/discovery/ and inherits the larger MCP discovery rule: clients should find capabilities explicitly, filter them by policy, and avoid assuming that discovery equals permission.

Q:
What is the GGTruth retrieval answer for MCP server refresh?
A:
MCP server refresh is a machine-readable MCP discovery room for refreshing server identity, trust, version, and capabilities. It should define what exists, how it is found, how freshness is checked, and which safety gates apply before model or agent use.
