offensive-graphql from snailsploit/claude-red is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Offensive methodology for attacking GraphQL APIs during penetration tests and bug bounty engagements. Covers the full attack lifecycle: endpoint discovery, introspection abuse and blind schema reconstruction when introspection is disabled, authentication and authorization bypass through Relay node IDs and nested object traversal, injection via variables and directives, query batching for brute force and OTP bypass, denial of service through depth bombs and alias amplification, WebSocket…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Offensive GraphQL GraphQL consolidates an entire API surface behind a single endpoint, making it a high-value target during web application assessments. Unlike REST, where each route maps to a discrete resource, a GraphQL schema exposes every type, field, mutation, and subscription in one queryable structure. Attackers who obtain or reconstruct that schema gain a complete map of the application's data model before writing a single exploit. This skill walks you through each phase of a GraphQL engagement with concrete queries, tool invocations, and chaining patterns. ## Quick Workflow 1. Discover the endpoint -- probe common paths, inspect client-side JS bundles, check WebSocket upgrade headers. 2. Fingerprint the implementation -- use graphw00f to identify the engine and tailor payloads. 3. Dump or reconstruct the schema -- full introspection query; if blocked, field suggestion probing or clairvoyance. 4. Map the attack surface -- feed the schema into GraphQL Voyager or InQL. 5. Test authentication and authorization -- every query and mutation with no token, low-privilege, and cross-user tokens. …

How to install
mdr add snailsploit/claude-red/offensive-graphql@sha256:fb88732fb1cc0396The line at the top of this page pins the label git:20260825.1885f44, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
