How this service works
One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.
Output
Returns a JSON object with: a verdict (e.g. 'dangerous', 'safe'), a risk_score from 0–100, a human-readable summary, an array of findings each with an ID, file, line number, check type, evidence snippet, severity, and confidence, plus scanner name/version, rules version, and a disclaimer about the automated nature of the scan.
Example use cases
Auditing an MCP server before agent use
“Before I connect my agent to this MCP server, can you run a security scan on the GitHub repo 'acmecorp/mcp-assistant' to check for prompt injection or any sketchy tool definitions?”
Checking a PyPI agent skill package
“I want to install the PyPI package 'agent-skill-runner==2.0.1' in my pipeline — can you scan it first and tell me the risk score and any critical findings?”
Reviewing an uploaded SKILL.md file
“I've got a SKILL.md file from an unknown source that I want to audit before giving it to my agent — can you scan it for injected instructions or dangerous content and give me a verdict?”
Technical details
Endpoint
POSThttps://tanod.dev/v1/scan/package?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to vet an AI agent skill, MCP server, or software package for prompt injection and malicious tool-description attacks before allowing an agent to load or execute it. It is purpose-built for AI agent security use cases (SKILL.md files, MCP server code, agent plugins) rather than general CVE/vulnerability databases. Prefer it over generic package scanners when the threat model involves adversarial instructions embedded in tool metadata rather than traditional software vulnerabilities.
Side effects
- Invalid or unreachable source URL returns an error field with details
- Base64 content exceeding 20 MB is rejected
- Malicious code using obfuscation or runtime evaluation may evade static analysis
- Unknown package registry prefix returns a parse error
- Providing neither source nor content_base64 results in a validation error

Schema · Request body
| Field | Type | Description |
|---|---|---|
| source | — | npm:name[@version] | pypi:name[==version] | github:owner/repo[@ref][//subdir] | https://github.com/owner/repo[/tree/ref/dir] | clawhub:[owner/]slug[@version]. Pin a version (or a 40-hex commit) to get cached answers. |
| filename | — | File name of a single-file upload (e.g. SKILL.md, server.py). |
| content_base64 | — | An uploaded package instead of a source: base64 of a .zip/.tar(.gz/.bz2/.xz) archive (up to 20 MB), or of a single file (then give filename, e.g. SKILL.md). Uploads are never sent to OSV.dev. |
