graphql-pentest SKILL.md skillA
graphql-pentest from dreadnode/capabilities is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dreadnode/capabilities/graphql-pentest@git:20260605.f6eaa61Pins git:20260605.f6eaa61 in mdr.lock. Pin the fingerprint instead.

GraphQL endpoint discovery, resource abuse (batching, alias amplification, circular fragments, deep nesting), introspection exploitation, backend fingerprinting (Apollo vs graphql-java vs Yoga vs Hasura), and CSRF via content-type differentials. Use when target has GraphQL endpoints, JS source references /graphql paths, or introspection schema is available.
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
# GraphQL Pentesting
Systematic GraphQL security testing from endpoint discovery through resource abuse, auth bypass, and information disclosure. Covers the full attack surface: batching DoS, alias amplification, circular fragment crashes (CWE-674), deep nesting, introspection mining, content-type CSRF, and persisted query abuse.
## When to Use
- JS source contains `fetch`/`axios`/`gql` calls to `/graphql` paths
- Proxy sitemap shows `application/json` POST to GraphQL-shaped endpoints
- Static analysis matches flag GraphQL operations, mutations, or schema fragments
- Target uses known GraphQL frameworks (Apollo, graphql-java, Hasura, Yoga, Strawberry)
- Error responses contain `extensions.code`, `GRAPHQL_VALIDATION_FAILED`, or `PersistedQueryNotFound`
## Base Request
All GraphQL requests use this template (abbreviated as `GQL` in examples below):
```bash
curl -sk -X POST "https://TARGET/graphql" \
-H "Content-Type: application/json"
```
## Phase 1: Endpoint Discovery
### Common Paths
Probe these paths with `POST {"query":"{__typename}"}` and `Content-Type: application/json`:
```
/graphql /api/graphql /v1/graphql

How to install
mdr add dreadnode/capabilities/graphql-pentest@sha256:19a3295ec305858eThe line at the top of this page pins the label git:20260605.f6eaa61, 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.
