Noir is a SAST tool that reads source code and extracts the endpoints an application exposes — paths, methods, parameters, headers, cookies, and the source files behind them. Shadow APIs, deprecated routes, and undocumented handlers come out as part of the same inventory; they aren't a separate mode.
The inventory feeds three audiences:
Human reviewers. Security engineers and code auditors get a focused list of attacker-reachable entrypoints — paths, parameters, source files, tags — instead of skimming the whole repo.
AI auditors. LLM-based SAST agents get the same focused list, plus per-endpoint review context (--include callee for 1-hop callees, --ai-context for guards, sinks, validators, and signals).
DAST tools. ZAP, Burp Suite, Caido and Gori get a real route list to scan, including paths they would never have reached by crawling.
What Noir does
Endpoint extraction. Static analysis across 50+ frameworks. Returns endpoints, parameters, headers, cookies, and the source files they came from.
LLM fallback. Hand unsupported frameworks (or one-off custom routing) to OpenAI / Ollama / etc. when static rules don't apply.
Output for the next stage. JSON, YAML, OpenAPI, SARIF, cURL, Postman, HTML — whichever format the next tool in the pipeline reads.
DAST integration. Pipe directly into ZAP, Burp Suite, Caido or Gori as a proxy target, or export OpenAPI for them to import.
AI SAST context. The endpoint inventory (and, with --include callee, the 1-hop functions each handler invokes) is the focused context an LLM auditor needs to find attacker-reachable bugs. --ai-context goes further and attaches aggregated review context per endpoint — guards, callees, sinks, validators, and signals — so the LLM doesn't have to rediscover them.
CI/CD. GitHub Action, SARIF output, exit codes — fits the pipeline you already have.

Roadmap
Noir started as a WhiteBox testing aid: extract endpoints from source so DAST can scan them more accurately. The job has grown — the same inventory now feeds human auditors and AI SAST agents too. The goal from here is to serve all three consumers equally well: humans reviewing the code, LLMs auditing it, and DAST tools scanning it.
From here:
Broaden language and framework coverage; keep accuracy honest with per-framework fixtures.
Lean harder on LLMs for the cases static analysis can't reach.
Enrich the per-endpoint review context (guards, callees, sinks, validators, signals) so human reviewers and AI auditors share the same focused view of each handler.
Keep DAST integration first-class — OpenAPI, proxy targets, and direct hand-offs to ZAP / Burp / Caido.
