Tools 5

scan_mcp_url
annotations: none low

Fetch a remote MCP server's /tools/list (or any JSON tool listing) and scan every tool's name + description + inputSchema against the canonical 30+ injection-pattern rules. Returns a structured report: per-tool findings, severity counts, score 0-100, verdict, and remediation hints. Free tier: 5 scans/day per key. Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files. Safe to call repeatedly with identical inputs (idempotent). Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool for security assessment, threat detection, or vulnerability analysis. Suitable for automated security scanning and risk evaluation. When NOT to use: Do not rely solely on this tool for production security decisions. Always combine with manual security review. Args: url (str): The url to analyze or process. api_key (str): The api key to analyze or process. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage. Pro/Enterprise tiers require a valid MEOK API key passed via the MEOK_API_KEY environment variable. - Rate Limits: Free tier: 10 calls/day. Pro tier: unlimited. Rate limit headers are included in responses (X-RateLimit-Remaining, X-RateLimit-Reset). - Error Handling: Returns structured error objects with 'error' key on failure. Never raises unhandled exceptions. Invalid inputs return descriptive validation errors. - Idempotency: Fully idempotent — calling with the same inputs always produces the same output. Safe to retry on timeout or transient failure. - Data Privacy: No input data is stored, logged, or transmitted to external services. All processing happens locally within the MCP server process.

url str api_key str
audit_tool_descriptions
annotations: none low

Audit a JSON string containing a tool list (paste from your own MCP server's tools/list output). Same rule catalogue as scan_mcp_url — useful when the server is behind auth or not yet deployed. `tools_json` accepts either: a raw list, or {"tools": [...]}, or {"result": {"tools": [...]}}. Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files. Safe to call repeatedly with identical inputs (idempotent). Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool for security assessment, threat detection, or vulnerability analysis. Suitable for automated security scanning and risk evaluation. When NOT to use: Do not rely solely on this tool for production security decisions. Always combine with manual security review. Args: tools_json (str): The tools json to analyze or process. api_key (str): The api key to analyze or process.

api_key str tools_json str
signed_safety_report
annotations: none low

Issue a cryptographically signed safety report for the scanned MCP server. Returns a cert with a public verify URL anyone can hit to confirm the audit happened on the date claimed. Pro / Enterprise tier only. Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files. Safe to call repeatedly with identical inputs (idempotent). Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool for security assessment, threat detection, or vulnerability analysis. Suitable for automated security scanning and risk evaluation. When NOT to use: Do not rely solely on this tool for production security decisions. Always combine with manual security review. Args: subject (str): The subject to analyze or process. findings_json (str): The findings json to analyze or process. score (int): The score to analyze or process. note (str): The note to analyze or process. api_key (str): The api key to analyze or process. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage. Pro/Enterprise tiers require a valid MEOK API key passed via the MEOK_API_KEY environment variable. - Rate Limits: Free tier: 10 calls/day. Pro tier: unlimited.
