AI agents call vitour_read_snippet to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It is a straightforward read operation with no capability to alter system state or trigger external actions. The explicit 'read-only' designation and absence of any write/execute/delete language confirm the Read category.
