# Security Audit Report — atla-mcp-server - **Report ID:** `fbcfe1ab-8e1c-448e-873f-16f62b4c2f88` - **Generated:** 2026-07-21T22:30:13.143322+00:00 - **Signature:** unsigned (cosign keyless signing runs in CI; Req 22.4) ## 1. Executive Summary **Badge:** Verified (composite) **Security score:** 97.85 | Scanner | Badge | | --- | --- | | agent-audit-kit | Caution | | agentshield | unavailable | | bearer | Verified | | cisco-skill-scanner | Verified | | nerlo-behavioral | Verified | | nerlo-install-instruction | Verified | | osv-scanner | unavailable | | trivy | Verified | | Severity | Findings | | --- | --- | | critical | 0 | | high | 0 | | medium | 3 | | low | 3 | atla-mcp-server meets the registry's verification bar at scan time. Keep monitoring enabled — verification reflects this commit, not future releases. ## 2. Source Provenance - **Repository:** https://github.com/atla-ai/atla-mcp-server - **Commit scanned:** `unknown` - **License:** MIT - **Maintainer:** Atla - **Version:** unknown ## 3. Per-Scanner Detail ### agentshield (v1.4.0) — unavailable / n/a No findings. ### cisco-skill-scanner (v2.0.11) — Verified / 95.5 - **[low] Hidden data file detected** — Hidden file found: .pre-commit-config.yaml. Hidden files may contain concealed configuration or data that should be reviewed. (/repo/.pre-commit-config.yaml:None) - **[low] Vague skill description** — Skill description is too short (16 chars). Provide detailed explanation. (/repo/SKILL.md:None) - **[informational] Skill does not specify a license** — Skill manifest does not include a 'license' field. Specifying a license helps users understand usage terms. (/repo/SKILL.md:None) ### agent-audit-kit (v0.3.26) — Caution / 83.0 - **[medium] No lockfile present** — A package manifest exists but no lockfile was found. Without lockfiles, dependency versions float and can be silently updated. (pyproject.toml:None) - **[low] MCP server repo missing SECURITY.md or security_contact** — A repository whose name or pyproject keywords declare it as an MCP server ships without a top-level SECURITY.md AND without a 'security_contact' entry in marketplace.json / pyproject.toml / package.json. Anthropic's April 2026 SECURITY.md guidance makes this the baseline expectation so researchers have a channel. (SECURITY.md:None) - **[medium] Third-party GitHub Action not pinned by full commit SHA** — A workflow in '.github/workflows/' uses a third-party Action ('owner/action@ref') where 'ref' is a tag or branch name instead of a 40-character commit SHA. A repo-takeover of the Action's publisher can re-point the tag to a malicious revision — the downstream repo consuming it will happily run the new code with 'GITHUB_TOKEN' and write permissions. GitHub's April 2026 Security Roadmap ships Immutable Actions and makes SHA pinning the default policy. (.github/workflows/publish.yaml:15) - **[medium] Third-party GitHub Action not pinned by full commit SHA** — A workflow in '.github/workflows/' uses a third-party Action ('owner/action@ref') where 'ref' is a tag or branch name instead of a 40-character commit SHA. A repo-takeover of the Action's publisher can re-point the tag to a malicious revision — the downstream repo consuming it will happily run the new code with 'GITHUB_TOKEN' and write permissions. GitHub's April 2026 Security Roadmap ships Immutable Actions and makes SHA pinning the default policy. (.github/workflows/publish.yaml:42) ### bearer (v2.0.2) — Verified / 100.0 No findings. ### nerlo-behavioral (v0.1.0) — Verified / 100.0 No findings. ### nerlo-install-instruction (v0.1.0) — Verified / 100.0 No findings. ### trivy (v0.71.0) — Verified / 100.0 No findings. ### osv-scanner (v2.3.8) — unavailable / n/a No findings. ## 4. Threat Model Threat model synthesis has not yet run for this scan. This section is generated by the registry's LLM pipeline (Req 22.3) and will appear in the next regeneration of this report. ## 5.
