Audit MCP configs and skill files for over-broad scope and injection risk. 6 of 8 free.
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.
Incident-reporting deadlines from the law: CRA, NIS2, DORA, GDPR, HIPAA, SEC 8-K. 6 of 9 tools free.
Built for human creators. Register a timestamp on Polygon proving you made something, the moment you did. Your file is never uploaded, watermarked, or altered: only its cryptographic fingerprint ever reaches spArxx.io, zero-knowledge by design. A human still provisions the account behind the connection. This is deliberate, since this registration only means something with a human behind it.
Pre-send EVM address checks: free pre-check, $0.01 check, $0.05 deep scan. x402: payment is auth.
Free website privacy scanner for pre-consent cookies, trackers, consent, policy, and HTTPS/TLS.
Persistent knowledge graph for AI-augmented teams. Store decisions, findings, and standing rules across agent sessions with semantic search and typed connections. Includes cross-session memory, audit trail, workspace isolation, and secret detection. Built for teams running agents that need to remember. Free until launch with team tier as default, anon trial available.
Discover Agents and MCP capabilities with versions, permissions, and real-work trust context.
Hextrap's MCP Connector protects your LLM coding sessions from installing malicious dependencies, typosquats, unpopular packages, and enforces your strict allow and deny lists. No setup means your LLM uses MCP to configure itself to use Hextrap's proxy's automatically, enforcing your firewall rules immediately. Manage your allow and deny lists right from your favorite LLM.
DNS and email security: check SPF, DKIM, DMARC, DNSSEC, DANE and build the records. 45 tools.
Pay-per-call x402 tools for AI agents: web, onchain, risk, finance & prediction data on Base.
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.
Verifies which domain officially belongs to a software product, AI tool, or company, so the agent stops handing users lookalike download sites. Ownership only, never safety. Every verdict is backed by reproducible evidence. Tools: get_official_url(name), verify_url(url). No auth required.
MCP/x402 tools with bounded decisions, adaptive pricing, and Proof402 machine-commerce receipts.
