Gets details about a specific GitHub repository connected to Jules.
AI agents call jules_get_source to retrieve information from Jules MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about a GitHub repository—a read-only operation with no side effects. It does not create, modify, delete, or execute any changes. The severity is low because repository metadata disclosure has minimal risk unless the repository is private and contains sensitive code, but the tool itself performs only data retrieval.
From the tool's definition Tool name 'jules_get_source' and description 'Gets details about a specific GitHub repository connected to Jules' indicate retrieval of repository metadata without modification or execution.
