    GraphQL Introspection Checker

    Detect exposed GraphQL endpoints and analyze schemas for sensitive data, dangerous mutations, and security misconfigurations.

    What does this tool check?

    Endpoint Discovery

    Probes 10+ common GraphQL paths to find exposed endpoints

    Introspection Check

    Tests if full schema introspection is enabled in production

    Sensitive Data Detection

    Identifies types and fields that may expose PII, credentials, or secrets

    Schema Analysis

    Catalogs all queries, mutations, and types with security scoring

    Why is exposed introspection dangerous?

    GraphQL introspection allows anyone to discover your entire API schema — every query, mutation, type, and field. While useful in development, leaving it enabled in production is like publishing your database schema publicly. Attackers can use it to find sensitive fields (passwords, tokens), discover admin mutations, and craft targeted attacks against your API. Major security frameworks (OWASP, Apollo) recommend disabling introspection in production environments.
