Get webhook config for a repository webhook
AI agents call get_repository_webhook_config to retrieve information from Mcp Github without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves webhook configuration information from a GitHub repository. It performs no mutations, deletions, or side effects—it only reads and returns existing data. The blast radius of misuse is minimal; an attacker would only gain visibility into webhook endpoints and settings already configured on the repository, which does not enable unauthorized actions beyond information disclosure.
From the tool's definition Tool name 'get_repository_webhook_config' with description 'Get webhook config for a repository webhook' indicates a retrieval operation. The 'get_' prefix and verb 'Get' confirm it retrieves existing webhook configuration data without modification.
