github_list_prs
AI agents call github_list_prs to retrieve information from Integrations MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Listing pull requests is a non-destructive retrieval operation. It queries existing data from GitHub without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker could only view PR information already accessible to the authenticated account.
From the tool's definition Tool name 'github_list_prs' indicates listing pull requests from GitHub. The 'list' action is a read operation that retrieves data without modification or side effects. No description is provided, but the name strongly suggests a query operation.
