security-scanning

security-scanning is a skill for Claude Code, Codex from Tyox-all/Weave_Protocol. It costs 46 tokens per session (468 once invoked), scanned A, original, Apache-2.0.

A scanner for finding secrets, personal information, prompt injection, dangerous patterns, and suspicious MCP servers. MCP servers provide tools that an AI agent can call.

In plain words
What is it for?
Use it to scan content, check strings for secrets or personal information, vet MCP server manifests and permissions, and detect typosquatting such as a fake package name resembling a trusted one.
Why use it?
It helps catch exposed credentials, sensitive data, malicious instructions, and unsafe tool integrations before they are processed or installed.

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.

Security

Grade A, and why

security-scanning 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 4d ago.

The scan reads SKILL.md. This mod also ships 25 executable files (src/analyzers/code-analyzer.ts, src/analyzers/exfiltration-detector.ts, src/analyzers/index.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Security Scanning with Mund

Overview

Mund detects security issues in content and MCP servers. Use it before processing untrusted input or installing MCP servers.

MCP Tools

Tool Purpose
mund_scan Scan content for all security issues
mund_check_secret Check if a string is a secret
mund_check_pii Detect personally identifiable information
mund_scan_mcp_server Vet MCP server manifest before install
mund_check_typosquatting Detect name squatting attacks
mund_audit_mcp_permissions Analyze MCP tool capabilities

Quick Examples

Scan for secrets

mund_scan({ content: "API key: sk-abc123..." })
→ { safe: false, issues: [{ rule_id: "openai_api_key", severity: "critical" }] }

Vet MCP server

mund_scan_mcp_server({ manifest: "<server.json>" })
→ { recommendation: "DO_NOT_INSTALL", issues: [...] }

Check typosquatting

mund_check_typosquatting({ name: "githib-mcp" })
→ { is_suspicious: true, similar_to: ["github"] }

Detection Categories

  • Secrets: API keys, tokens, private keys, database URLs
  • PII: SSN, credit cards, emails, phone numbers
  • Injection: Prompt injection, jailbreak, instruction override
  • MCP Servers: Malicious descriptions, typosquatting, dangerous permissions

When to Use

  1. Before processing any untrusted input
  2. Before adding MCP servers to claude_desktop_config.json
  3. When handling user-provided content
  4. Periodically in long-running conversations

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.
