AI Summary

This major feature release introduces the `triage_cve` orchestrator for concurrent analysis of CVE data and implements significant security hardening measures. It adds new data sources, MCP resources, and prompts while maintaining additive compatibility with existing tools.

Key Highlights

  • Introduction of the `triage_cve` orchestrator for concurrent analysis of NVD, EPSS, and CISA KEV data with composite scoring.
  • CISA KEV hard override ensuring listed CVEs are always scored as CRITICAL regardless of other metrics.
  • Security hardening including SSRF defense, removal of sampling handlers, and centralized secrets management.
  • New data sources: VulnCheck NVD++, CIRCL hashlookup, and HIBP Pwned Passwords range API.
  • Support for Streamable-HTTP transport via `MCP_TRANSPORT=http` and expanded MCP resources and prompts.

New Features

  • `triage_cve` orchestrator with depth levels (quick, standard, deep) and SSVC v2 decision support.
  • VulnCheck NVD++ fallback mechanism for when NIST NVD is unreachable.
  • New MCP resources: `kev://catalog`, `epss://scores/{cve_id}`, and `manifest://tool-hash`.
  • New MCP prompts: `patch_decision`, `compare_and_prioritize`, and `dependency_triage`.
  • HIBP Pwned Passwords range API integration.
  • CIRCL hashlookup integration for known-good allowlists.
  • Streamable-HTTP transport support (`MCP_TRANSPORT=http`).

Full Release Notes

## CVE MCP Server v0.2.0

A major feature release. **Additive** — all existing tools remain registered; the new `triage_cve` orchestrator is the recommended entry point.

### ⭐ Orchestration
- **`triage_cve`** — one tool call fans out NVD + EPSS + CISA KEV (+ public PoC discovery) concurrently, computes the composite risk score, and returns a clean report. `depth` = `quick` / `standard` / `deep`; **`deep`** also emits an SSVC v2 gated decision (CISA Deployer model → `Act` / `Attend` / `Track*` / `Track`).
- Transparent **VulnCheck NVD++ fallback** used automatically when NIST NVD is unreachable or throttled.

### 🎯 Scoring
- **CISA KEV hard override** — a KEV-listed CVE is always **CRITICAL** (score clamped ≥ 76), regardless of CVSS/EPSS.
- **`scoring_version`** stamped into `triage_cve`, `calculate_risk_score`, and `health_check`.
- CVSS reframed as a **severity** signal (not exploitation-likelihood), per Allodi & Massacci 2014.

### 🔌 New data sources
- **VulnCheck NVD++** (NVD-schema fallback), **CIRCL hashlookup** (known-good allowlist), **HIBP Pwned Passwords** range API (keyless k-anonymity).

### 🧩 MCP enhancements
- **Resources**: `kev://catalog`, `epss://scores/{cve_id}`, `manifest://tool-hash` (SHA-256 over the registered tool surface).
- **Prompts**: `patch_decision`, `compare_and_prioritize`, `dependency_triage`.
- **Streamable-HTTP transport** via `MCP_TRANSPORT=http` (stdio remains the default).
- Expanded `health_check` (scoring version, manifest hash, configured-key status).

### 🔐 Security hardening
- Server **never** registers a sampling handler / never issues `sampling/createMessage` (Unit 42 MCP-sampling attack vector).
- **SSRF** defense: scheme allowlist + resolve-then-validate (rejects private/reserved IPs).
- Secrets centralized as Pydantic `SecretStr`.

### 🏗️ Infrastructure
- Multi-stage non-root **Dockerfile** + `.dockerignore`.
- SQLite **WAL** pragmas for concurrent reads; null-object rate limiter; fixed-interval deterministic retry; async fan-out helper; static Admiralty source-trust table.

**Verified:** ruff clean, 30/30 tests passing.
