OAuth website audits: security, SEO, AI visibility, integrations, accessibility and performance.
Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Threat intel for AI agents: IOCs, CVEs (EPSS/KEV), wallet sanctions and age, domain and URL checks.
Scan, fix, verify and monitor DNS: SPF, DMARC, DKIM, propagation, health, expiry. Validated fixes.
Signed third-party verdict on what an npm package or file does when run. No key, no signup.
Lead validation over MCP: KVK/KBO register, EU VAT, sanctions and email checks with sources.
Smart contract security screening for Base. Check any contract or token for risk before interacting with it: Solidity source verification, upgradeable proxies and admin or mint powers, holder concentration, dangerous selectors, and B20 issuer powers. It surfaces the usual rug pull and scam indicators. The free tool needs no wallet and no API key; the paid Flash Audit (3.49 USDC over x402) returns a report with an anchored SHA-256. Payment is the only gate.
Agent permissions for the files your team shares
Verify identities, screen for AML/PEP risk, and detect fraud across Africa, Asia, Europe, and the Americas — directly from your AI assistant, with no custom integration code required.
Domain exposures: breaches, infostealers, ULP heap, cookies. Counts and samples, free.
Auth, billing, plans, feature flags and roles for your SaaS, set up from your coding agent.
Honeypot probe data: IP reputation, scanners, CVE probing, TLS and SSH fingerprints.
Verify claims, resolve FIGI identity, extract claims, and sign x402 delivery receipts over MCP.
Check an npm/PyPI package before an AI agent installs it: 5 focused supply-chain tools.
Collision-first MCP diagnostics for MCP, API, webhook and agent failures. Returns structured evidence, bounded repair guidance, agent compatibility checks and safe recovery routing.
Audit MCP configs and skill files for over-broad scope and injection risk. 6 of 8 free.
Website monitoring: add sites, configure and run monitors, read health, review results, apply fixes.
Incident-reporting deadlines from the law: CRA, NIS2, DORA, GDPR, HIPAA, SEC 8-K. 6 of 9 tools free.
Free MCP server of security & dev API tools -- supply-chain, CVE, DNS, WHOIS, OFAC, Cosmos SDK.
Test and debug your AI agent's Web Bot Auth (RFC 9421) signature: is it valid, and what to fix?
