greet · Server Pdf MCP: Risk & Policy

WHAT IT DOES

What greet does on Server Pdf

AI agents call greet as a supporting operation in Server Pdf workflows.

WHY IT NEEDS A POLICY

Why greet needs a policy

Greeting a user is a purely communicative/presentational action with no data retrieval, modification, execution, or financial implications. It does not read, write, or alter any data. Confidence is slightly reduced because the description is minimal and the tool appears in a PDF server context which is unusual for a greeting tool.

From the tool's definition Tool name is 'greet' and description says 'Greet the user'
