WHAT IT DOES

What api_graphql_introspect does on Zebbern Kali MCP

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

RISK

Why api_graphql_introspect is rated Low

GraphQL introspection queries retrieve schema information, types, and available queries from an endpoint. While this gathers intelligence that could inform follow-up attacks, the introspection operation itself is read-only and causes no side effects.

From the tool's definition Tool description states 'Introspect a GraphQL endpoint to discover schema, types, and queries' — introspection is a passive reconnaissance operation that retrieves metadata about a GraphQL API without modifying or executing arbitrary operations.
