WHAT IT DOES

What get_wal_archive_status does on Mcpg

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

RISK

Why get_wal_archive_status is rated Low

The 'get_' prefix and 'status' suffix strongly indicate this is a read-only query tool that retrieves information about PostgreSQL WAL archive status. While the description is empty, the tool naming convention and context (a PostgreSQL MCP server with other analytical tools) support classification as Read.

From the tool's definition Tool name 'get_wal_archive_status' contains 'get', which indicates a retrieval operation. The name pattern suggests querying the status of WAL (Write-Ahead Logging) archives without modification.
