Tools & Capabilities Breakdown
Shieldapi MCP Tools (10)
check_url
Check a URL for malware, phishing, and other threats. Uses URLhaus + heuristic analysis.
check_password
Check if a password hash (SHA-1) has been exposed in known data breaches via HIBP.
check_password_range
Look up a SHA-1 hash prefix in the HIBP k-Anonymity database.
Shieldapi MCP is categorized under Security and uses a local stdio subprocess. In contrast, AI Distiller MCP belongs to Security using local stdio subprocess. Select Shieldapi MCP when you need capabilities focused on security and AI Distiller MCP when you require tools for security.
Run all security checks on a target (URL, domain, IP, or email). Most comprehensive scan.
scan_skill
Scan an AI agent skill/plugin for security issues across 8 risk categories (Snyk ToxicSkills taxonomy). Checks for prompt injection, malicious code, suspicious downloads, credential handling, secret detection, third-party content, unverifiable dependencies, and financial access patterns. Static analysis only — no code execution. Returns risk score (0-100), severity-ranked findings with file locations, and human-readable summary.
check_prompt
Detect prompt injection in text. Analyzes across 4 categories (direct injection, encoding tricks, exfiltration, indirect injection) with 200+ detection patterns. Designed for real-time inline usage before processing untrusted user input. Returns boolean verdict, confidence score (0-1), matched patterns with evidence, and decoded content if encoding obfuscation was detected. Response time <100ms p95.
check_mcp_trust
Get a multi-signal trust score for any MCP server endpoint. Analyzes security (domain reputation, SSL, SPF/DMARC), injection risk (tool description scanning), supply chain safety (toxic skill categories), reliability (uptime, latency, protocol compliance), and on-chain reputation (AgentProof ERC-8004). Returns composite trust score (0-100), tier (platinum/gold/silver/bronze/unranked), and detailed per-signal breakdown. Use this to evaluate whether an MCP server is safe to connect to.
AI Distiller MCP Tools (16)
distill_file
Extracts essential code structure from a single file - the core functionality of AI Distiller. Returns clean, structured code signatures optimized for AI context windows.
USAGE: Essential for providing accurate code context to AI assistants. Automatically detects language and extracts API signatures, types, and structure while removing unnecessary implementation details.
distill_directory
Extracts essential code structure from entire directories - the core functionality of AI Distiller. Processes all supported programming languages and returns structured API/code signatures optimized for AI context windows.
