+
+## Critical Findings (blocks PASS -- must fix)
+
+### SEC-001 -- 257 false positives from package-lock.json
+
+All 257 "secrets" findings are SHA-512 integrity hashes in `mcp-app/package-lock.json`. These are npm package integrity checksums, not secrets. Example:
+
+```
+"integrity": "sha512-abc123..."
+```
+
+**Why this matters:** The scanner flags any string matching cryptographic hash patterns. With 257 hits, this single file dominates the score and pushes the overall result to FAIL.
+
+**Action needed:**
+- **Option A:** Add `mcp-app/package-lock.json` to `.gitignore`. The lock file is not currently ignored (checked `.gitignore`). Since the container build runs `npm install` from `package.json`, the lock file is regenerated at build time. Removing it from the repo would also reduce noise in diffs.
+- **Option B:** No action from your side -- we have already excluded lock files from scanning on our end. However, Option A is still worth considering for general repo hygiene.
+
+---
+
+### LIC-002 -- 96 source files missing SPDX license headers
+
+The repo is licensed Apache-2.0 but 96 `.py` and `.sh` files are missing SPDX headers. This is a gated category in the audit -- a FAIL here means an automatic overall FAIL regardless of other scores.
+
+**Action needed:** Add the following line to the top of every `.py` and `.sh` file (after the shebang line, if present):
+
+```python
+# SPDX-License-Identifier: Apache-2.0
+```
+
+**Find all files that need updating:**
+
+```bash
+find . -name "*.py" -o -name "*.sh" | xargs grep -L SPDX
+```
+
+**Batch fix (one-liner for .py files without shebangs):**
+
+```bash
+find . -name "*.py" -exec grep -L SPDX {} \; | while read f; do
+  sed -i '1i# SPDX-License-Identifier: Apache-2.0' "$f"
+done
+```
+
+For files with shebangs (`#!/usr/bin/env python3`), insert the SPDX line on line 2 instead of line 1.
+
+---
+
+### PRI-001 -- Real email in test file
+
+- **File:** `tests/connection/ssh/test_timeout.py`, line 111
+- **Value:** `testuser@myhost.example.com`
+
+The domain `example.com` is an IANA-reserved domain (RFC 2606), so this is likely acceptable. However, the scanner flags it because it matches the `user@host` email pattern.
+
+**Action needed:** Confirm this is intentional. If so, no change is required -- we can add a suppression comment for future scans.
+
+---
+
+### CTR-007 -- ENV sets sensitive-looking value in Containerfile
+
+- **File:** `Containerfile`, line 67
+- **Value:** `ENV LINUX_MCP_SEARCH_FOR_SSH_KEY=True`
+
+The scanner flagged this because the variable name contains `SSH_KEY`, which matches patterns for sensitive configuration. On inspection, this is a boolean flag that controls whether the application searches for SSH keys at runtime -- it does not contain a key or secret itself.
+
+**Action needed:** This is a false positive given the actual value is just `True`. Two options:
+1. **No change** -- we can add this to our suppression list.
+2. **Consider renaming** to something less ambiguous, e.g., `LINUX_MCP_ENABLE_SSH_KEY_DISCOVERY=True`, to avoid triggering security scanners. This is optional.
+
+---
+
+## Recommended Findings (improves score, not blocking)
+
+### CTR-003 -- No .containerignore file
+
+The repo has no `.containerignore` file. Without one, `podman build` / `docker build` may copy unnecessary or sensitive files into the build context.
+
+**Action needed:** Create `.containerignore` with:
+
+```
+.env
+.env.*
+.git
+*.token
+__pycache__
+*.pyc
+.pytest_cache
+coverage/
+.venv/
+.vscode/
+.idea/
+*.egg-info/
+```
+
+---
+
+### LIC-005 -- No copyright notices in source files
+
+Source files have no copyright headers. While SPDX identifiers (LIC-002) are the blocker, adding copyright notices is best practice for Apache-2.0 licensed projects.
+
+**Action needed:** Add below the SPDX header in each source file:
+
+```python
+# SPDX-License-Identifier: Apache-2.0
+# Copyright (C) 2026 Red Hat, Inc.
+```
+
+Adjust the year and entity as appropriate for your project.
+
+---
+
+### DEP-002 -- 3 dependencies without upper bounds
+
+Three dependencies in `pyproject.toml` use `>=` without an upper bound:
+
+| Dependency | Current spec |
+|-----------|-------------|
+| `litellm` | `>=1.80.16` |
+| `pydantic-settings` | `>= 2.12.0` |
+| `pydantic` | `>= 2.12.5` |
+
+**Note:** We see the comment in `pyproject.toml` explaining this is intentional due to your Renovate `in-range-only` strategy -- unbounded ranges ensure Renovate notifies you about all new versions, including major bumps with security fixes. This is a valid tradeoff.
+
+**Action needed:** None required if the Renovate strategy is working as intended. The scanner flags this as a general best practice but your documented rationale is sound. For the audit, we can suppress this finding with a note.
+
+---
+
+### SBX-001 -- 5 test files write to absolute paths
+
+Several test files reference absolute paths under `/var/log/`:
+
+| File | Paths referenced |
+|------|-----------------|
+| `tests/test_config.py` | `/var/log/custom`, `/var/log/test`, `/var/log/my-app/2024` |
+| `tests/utils/test_validation.py` | `/var/log/messages`, `/var/log/../../etc/hosts` |
+| `tests/tools/test_logs.py` | `/var/log/test.log`, `/var/log/remote.log` |
+
+These are in test files and appear to be used for config validation and path traversal checks (the `../../etc/hosts` path is a security test, which is good). Risk is low.
+
+**Action needed:** Consider using `tmp_path` pytest fixtures or `/tmp` paths where possible. For path validation tests (like the traversal check), the current approach is fine.
+
+---
+
+## Clean Categories (no findings)
+
+| Category | Grade | Notes |
+|----------|-------|-------|
+| Authentication patterns | A | No hardcoded credentials or auth bypasses |
+| Network boundaries | A | Proper network access controls |
+| Output safety | A | No injection or escape issues |
+
+---
+
+## How to Run the Audit Yourself
+
+```bash
+git clone git@gitlab.cee.redhat.com:afarley/ai-tool-security-check.git
+cd ai-tool-security-check
+python3 bin/skill-audit --fix-hints /path/to/linux-mcp-server/
+```
+
+The `--fix-hints` flag provides actionable fix suggestions for each finding.
+
+---
+
+## Score Breakdown
+
+| Category | Current | After fixes |
+|----------|---------|-------------|
+| Secrets | F (257 false positives) | A (exclude lock files) |
+| Licensing (SPDX) | F (96 files) | A (add headers) |
+| Licensing (copyright) | C | A (add notices) |
+| Privacy | B | A (confirm example.com) |
+| Container | C | A (add .containerignore, review ENV) |
+| Dependencies | B | B (intentional, suppressed) |
+| Sandbox | B | B (test-only, low risk) |
+| Auth patterns | A | A |
+| Network | A | A |
+| Output safety | A | A |
+| **Overall** | **FAIL (62%)** | **PASS (~90%)** |
+
+**The two highest-impact fixes are:**
+1. Exclude `package-lock.json` from the repo or scanning (removes 257 false positives)
+2. Add SPDX headers to all 96 source files (unblocks the licensing gate)
+
+These two changes alone should move the score from FAIL to PASS.
