SAP Security Notes MCP Server

Ask questions about SAP Security Note metadata — Patch Day releases, CVSS scores, CVEs, affected components, and actively-exploited status — via the Model Context Protocol (MCP).

Server URL: https://notes.syntaai.com/mcp

Features

• 10 Tools — Patch Day summaries, note/CVE lookup, component exposure checks, exploited-in-the-wild status, month comparisons (all read-only)
• 4 Resources — Catalog info, latest Patch Day summary, component list, priority definitions
• 4 Prompts — Monthly patch briefing, exposure check, patch backlog prioritizer, CVE investigation
• No authentication required — public read-only data.
• stdio transport — run it locally with Claude Desktop or any MCP client

Example Interactions

Example 1: Patch Day Summary

User prompt: "What came out in July's SAP Patch Day?"

What happens:

• Returns counts by priority for 2026-07, the HotNews list with CVSS scores, top affected components, and new vs. updated notes

Tool used: get_patch_day_summary

---

Example 2: Active Exploitation

User prompt: "Are any SAP vulnerabilities actively exploited right now?"

What happens:

• Cross-references the catalog's CVEs against the CISA Known Exploited Vulnerabilities (KEV) snapshot and returns matches with KEV dates
• A zero-match answer is reported honestly, with what that does and does not mean

Tool used: get_exploited_notes

---

Example 3: Component Exposure

User prompt: "Here is my stack: SAP S/4HANA 2023, SAP_BASIS 758, BC-JAS-WEB — what applies to me?"

What happens:

• Each item is classified: application component (BC-JAS-WEB), software component optionally with a version (SAP_BASIS 758), or product/stack name from Maintenance Planner (SAP S/4HANA 2023)
• Software components match primarily against SAP's own published affected-component/version lists; a curated mapping fills in notes that have no published list. Application components match directly (exact + prefix)
• A pasted version gets a tier per matched note:
  1. Affected version confirmed — the version is in SAP's published list
  2. Component listed, your version not in the published list — not proof of safety, published lists can be summarized
  3. Component affected, version not assessed — no version given, or no published list to check (exact-string match only — never a range or "close enough" inference)
• Returns matching notes grouped by provenance, plus an honest "not assessed" bucket for anything that could not be classified or matched

Tool used: check_component_exposure

Data Sources & Honesty

• Canonical source: SAP's public Patch Day pages. As of v2.1, the catalog is built primarily from SAP's public, no-login Security Patch Day pages (support.sap.com/.../security-notes-news/<month>-<year>.html), not a private export. Each page publishes, per note: title (with CVE prefix), CVE ID(s), priority, CVSS, the affected product name(s), and the affected software-component/version list. Raw pages are cached in data/pages/ for reproducible rebuilds.
• Public metadata only. The catalog never contains SAP note body text or correction instructions — only what SAP already publishes openly: note numbers, titles, CVSS scores/vectors, CVE IDs, priorities, affected software components and their published version lists, dates, and public note URLs.
• Coverage window is stated, not implied. Current catalog: January 2026 – July 2026 (get_catalog_info always tells you exactly).
• Null-evidence rule. Absence from this catalog does not mean absence of vulnerability. Every tool says so on every not-found answer, and no tool ever fabricates a note, CVE, score, date, or version.
• Exploitation data comes from the public CISA KEV feed; the snapshot version and fetch date are recorded in the catalog for reproducibility.
• Public-evidence date policy. Exact release days ship only when publicly evidenced without login: the page's own stated Patch Day date for notes in its main table, or a date matching the CVE's public NVD published date. Everything else ships as null, with release_month retained (a note's presence on its public month page is the evidence for the month).
• Version lists are exact and verbatim. affected[].versions are kept exactly as SAP published them — no numeric coercion, no range expansion, no normalization (758, 75A, 2008_1_700, 10.0 are all real, unmodified formats). A version line SAP publishes in a form the parser can't parse cleanly (a typo, a "< X.Y.Z" threshold instead of a discrete list, a component name containing a space) is kept verbatim in versions_unparsed — never partially guessed.
• Matching behavior & provenance labels. check_component_exposure accepts application components (the legacy per-note header field, e.g. BC-MID-RFC — not published by pages, so it's null for notes added from pages only, never fabricated), software components (System → Status, e.g. SAP_BASIS, optionally versioned like SAP_BASIS 758), and product names (Maintenance Planner, e.g. "SAP S/4HANA 2023"). For a software component, matching is two-tier by provenance: PRIMARY is a direct, exact match against SAP's own published affected-component list (match_type: published_affected_list); FALLBACK is a curated, rationale-documented mapping (data/component_mapping.yaml) to application-component prefixes, used only for notes with no published list (match_type: mapped_software_component). Every match says which it is. When a version is given, each matched note also gets an exact-string-match tier (1 confirmed / 2 listed-but-version-mismatch / 3 not assessed) — never a range or "close enough" inference. Products resolve through the same software-component chain; release years in product names are echoed back only. Which support package level fixes a note always requires the full SAP note.
• Monthly updates on SAP Patch Tuesday: scripts/monthly_update.py <page-url> fetches and caches the new page, rebuilds the catalog fresh from every cached page, re-runs KEV, validates the schema, and runs a CI gate requiring every application component to have an explicit mapping disposition before the build is considered commit-ready.
• Community corrections welcome — open a PR against data/notes_catalog.json or data/component_mapping.yaml.

Quick Start

claude.ai (hosted)

Add a custom connector with URL (no login needed):

https://notes.syntaai.com/mcp

Claude Desktop (local, stdio)

{
  "mcpServers": {
    "sap-security-notes": {
      "command": "/path/to/venv/bin/python",
      "args": ["/path/to/sap-security-notes-mcp/server.py"],
      "env": { "MCP_TRANSPORT": "stdio" }
    }
  }
}

Deployment

git clone https://github.com/SYNTAAI/sap-security-notes-mcp
cd sap-security-notes-mcp
python3 -m venv venv && source venv/bin/activate
pip install -r requirements.txt

# Local stdio
MCP_TRANSPORT=stdio python server.py

# HTTP (this is how the hosted server runs — no authentication,
# the catalog is public read-only data)
MCP_NO_AUTH=1 PORT=8003 python server.py

# HTTP with OAuth (optional, if you self-host and want a login gate)
PORT=8003 SYNTAAI_ISSUER_URL=https://your-host python server.py

Adding a new month once its Patch Day page is live:

pip install -r requirements-dev.txt
python scripts/monthly_update.py \
  https://support.sap.com/en/my-support/knowledge-base/security-notes-news/<month>-<year>.html
pytest

This fetches and caches the page, rebuilds the catalog from every cached page in data/pages/ plus a fresh KEV pull, validates the schema, and runs the CI disposition gate (fails loudly if a new application component has no mapping decision in data/component_mapping.yaml yet).

One-time historical rebuild from all cached pages (used to migrate off the original xlsx-derived catalog in v2.1):

python scripts/backfill_from_pages.py --offline
