What is sast-mcp-server GEMINI.md?

A code-security scanning service that checks source code, dependencies, configuration, and Git history with available security scanners.

Use it to run vulnerability scans, scan Git history for secrets, perform baseline web scans, list installed scanners, suppress known findings, and export results in SARIF for automated pipelines.

It helps find vulnerabilities, leaked secrets, unsafe settings, and infrastructure problems before they reach production.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01416	$0.01416
Opus 5	$0.00708	$0.00708
Sonnet 5	$0.00283	$0.00283
Haiku 4.5	$0.00142	$0.00142

Security

Grade A, and why

sast-mcp-server GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Tool Purpose

This extension provides SAST (Static Application Security Testing) scanning capabilities. It can scan codebases for security vulnerabilities using industry-standard tools: Bandit (Python), njsscan (JavaScript/Node.js), Bearer (multi-language with data-flow analysis), Semgrep (30+ languages with community rule registry), Trivy (vulnerabilities, secrets, IaC), CodeQL (deep semantic analysis with taint tracking), Checkov (Infrastructure-as-Code policies), Gitleaks (deep secret scanning in git history), OSV-Scanner (Software Composition Analysis), and OWASP ZAP (Dynamic Application Security Testing via Docker orchestration).

Available Tools

scan_vulnerabilities — Scan a directory for security vulnerabilities (SAST)
scan_all — Run ALL installed scanners in parallel with deduplication
scan_git_history — Scan the entire .git history for leaked secrets (Gitleaks)
run_active_scan — Run a dynamic (DAST) baseline scan by orchestrating Docker Compose (ZAP)
export_sarif — Export scan results in SARIF 2.1.0 format for CI/CD
list_scanners — Check which scanners are installed and available
ignore_vulnerability — Suppress a known false positive
unignore_vulnerability — Re-enable a previously ignored finding
list_ignored_vulnerabilities — Show all currently suppressed findings
save_baseline — Save a scan result as a baseline for future comparison
compare_baseline — Compare current codebase against a saved baseline
upload_to_defectdojo — Import a SARIF export into a DefectDojo engagement
upload_to_github — Upload a SARIF report to GitHub Code Scanning
generate_fix_prompt — Build an LLM prompt to fix a finding as a unified diff
apply_patch — Apply an agent-generated unified diff to disk (via git apply)

Usage Patterns

Initial Setup

Always start by calling list_scanners to verify which tools are available on the user's system.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
