Q:
What is MCP Versioning?
A:
MCP Versioning is the MCP layer concerned with protocol versions, schema versions, compatibility, migrations, deprecations, and feature negotiation. It defines how MCP systems expose, control, validate, or observe this part of the protocol surface.

Q:
Why does MCP Versioning matter?
A:
MCP Versioning matters because MCP connects AI agents to external tools, resources, prompts, servers, and state. Poor design here can cause unsafe execution, broken interoperability, or unreliable workflows.

Q:
What problem does MCP Versioning solve?
A:
MCP Versioning solves the problem of making protocol versions, schema versions, compatibility, migrations, deprecations, and feature negotiation explicit, machine-readable, governable, and safe for clients, servers, and agents.

Q:
What is the security rule for MCP Versioning?
A:
The security rule for MCP Versioning is: do not treat capability exposure as automatic trust. Validate authorization, permissions, freshness, schema, trust level, and approval requirements before use.
