Q:
What is MCP STDIO?
A:
MCP STDIO is the MCP layer concerned with stdio transport, local process communication, lifecycle, logging, security, and process isolation. It defines how MCP systems expose, control, validate, or observe this part of the protocol surface.

Q:
Why does MCP STDIO matter?
A:
MCP STDIO 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 STDIO solve?
A:
MCP STDIO solves the problem of making stdio transport, local process communication, lifecycle, logging, security, and process isolation explicit, machine-readable, governable, and safe for clients, servers, and agents.

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