Skill Spector

Inspired by NVIDIA SkillSpector

AI Skill Scanner Online

Free security review for agent skills and MCP tool bundles. Inspect commands, files, network behavior, secrets, and attack chains before a local agent gets authority to run them.

What SkillSpector changes

Agent skills deserve the same security review as code that runs on your laptop.

NVIDIA SkillSpector frames skills and MCP servers as executable supply-chain artifacts: they can ship prompts, scripts, config, tool declarations, package installs, and data access. Skill Spector turns that model into a practical web workflow: collect the source, preserve the version, surface evidence, and make the risk easy to review.

Analysis pipeline

From skill source to reviewable findings.

01

Collect

Accept repositories, local folders, archives, SKILL.md files, MCP configuration, or pasted skill text.

02

Normalize

Inventory Markdown, Python, JavaScript, shell scripts, package metadata, and remote references.

03

Detect

Look for command execution, network access, credential handling, persistence, exfiltration, and prompt-injection risk.

04

Explain

Group evidence into findings, severity, risk score, recommendations, and reproducible source metadata.

Command execution

Flags shell execution, dynamic code patterns, install scripts, and other instructions that can run commands on a user machine.

Suspicious source files

Summarizes Markdown, scripts, archives, and executable files so reviewers can see what belongs in the skill package.

Secrets and downloads

Highlights credential-like strings, remote download commands, network access, and patterns that deserve manual inspection.

GitHub commit tracking

Public GitHub reports store the repository, source path, and scanned commit so future readers know exactly what was reviewed.

Detection map

Checks shaped around how agent skills actually gain power.

Instead of treating a skill as plain documentation, the scanner looks at the trust boundary it creates: what it asks the agent to do, which tools it exposes, where data can move, and whether the package can alter the local environment.

Arbitrary execution

Shell calls, subprocess use, install hooks, unsafe eval, and instructions that ask an agent to execute untrusted code.

Network and exfiltration

Downloads, callbacks, remote payload loading, webhook-style endpoints, and unusual outbound access patterns.

Secrets and local files

Credential-like strings, environment variable access, SSH keys, token handling, and broad filesystem reads.

Attack-chain context

Findings are written as reviewable chains so a maintainer can see how a harmless-looking step becomes risky.

MCP configuration

Reviews server definitions, tool surfaces, local command launchers, and configuration that expands an agent's authority.

Severity scoring

Risk scores separate informational review notes from high-risk behavior that needs manual inspection before installation.

For maintainers and teams

Reports that are useful after the first scan.

SkillSpector-style review is strongest when it becomes repeatable. Keep an auditable report for each source version, compare later changes, and give reviewers enough context to decide whether a finding is a blocker, a warning, or accepted risk.

JSON reports

Structured output for CI, dashboards, public report libraries, or downstream review workflows.

HTML summaries

Readable findings with evidence, severity, confidence, remediation, and source traceability.

Baseline suppression

Known findings can be baselined so teams can focus on new risk introduced by later changes.

Latest public reports

Open-source GitHub scans become crawlable reports with risk scores, findings, component lists, and source version history.

FAQ

AI skill scanner questions

What inputs can I scan?

Git repositories, SKILL.md URLs, zip URLs, local Markdown files, zip uploads, and pasted SKILL.md text.

Are GitHub reports public?

Public GitHub skills can be added to the report library automatically after scanning, including the scanned commit for traceability.

Is this a malware verdict?

No. The report is a security review aid. Treat high-risk findings as review prompts before trusting a skill with local tools or credentials.

How does this relate to NVIDIA SkillSpector?

The page follows SkillSpector's public project model: inspect agent skills and MCP surfaces as executable artifacts, then report risky behaviors with evidence.

Can teams use results in CI?

Yes. Structured reports and baselines make it possible to track new findings over time instead of re-reviewing every known warning by hand.
