Trust infrastructure for AI agents. Check an AI agent or endpoint before invocation using reliability monitoring, endpoint verification, reputation signals, and a machine-readable trustDecision. Includes a read-only MCP trust check by URL with no AgentTrust API key required.
The PropelAuth Integration MCP Server helps you and your favorite AI agent integrate PropelAuth as quickly and easily as possible into your project. Whether you're integrating PropelAuth into your Next.js project or your FastAPI backend, the Integration MCP Server will ensure your AI agent has the best context possible for a successful integration.
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.
Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for 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.
MCP-native Trust Infrastructure for AI Agents. Persistent encrypted memory with Trust Quotient.
Classify data safety before storing or sharing. GDPR, HIPAA, PCI-DSS, CCPA. AI-powered.
Verify photos are real camera captures, not AI: C2PA and RAW+JPEG forensics. OAuth or API key.

Read-only MCP server for turva.dev's published service catalog, pricing and contact details. Five tools return JSON, including dated agent-readiness and security evidence with verification links. Connect over Streamable HTTP without an API key. The server answers questions about turva.dev and does not scan other websites or run audits.
Pay-per-call safety checks for AI agents: screen a crypto address or URL before you transact.
Query OSV.dev for package vulnerabilities and batch-audit dependency lists via MCP.
OCR for images and Korean ID documents
security tools for AI agents: URL safety scanning, prompt injection detection (200+ patterns), email/password breach checks via HIBP, domain & IP reputation analysis, and AI skill supply chain scanning. Free tier (3 calls/day) or pay-per-request with USDC micropayments via x402.
Scans text for personally identifiable information — emails, phone numbers, SSNs, credit card numbers, physical addresses, names — and returns a redacted version. Built for agents sanitizing user content, support tickets, logs, or documents before storage, sharing, or feeding into another LLM call. Pay-per-call via x402 (USDC on Base): $0.01/call, no account or API key. tools/list and /openapi.json are free for discovery.
Deterministic runtime enforcement of step order for AI agents: ALLOW/DENY before a step runs.
Query Microsoft Patch Tuesday security updates (MSRC) with EPSS and CISA KEV enrichment
Query WHOIS/RDAP information for domains, IP addresses, CIDR prefixes and ASNs. Self-hostable.
Free spend report from an agent log, no key. Hosted proxies: caps, audit export, buy calls.
