Pugi is an AI product team in your chat. Describe a business in a few sentences and Pugi plans, designs, builds and checks a real website, shows a live preview, and puts it live on its own address. Ask for changes in plain words. Pugi also draws four whole logos for a business name with a brand kit, checks any public website or GitHub repository for leaked keys, vulnerable dependencies and risky code, and helps you start from public site templates. Sign in with a Pugi account (OAuth).
Scoped credential retrieval for AI agents, with audit events and revocable future access -- https://gazebohq.com
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.
Check before your agent installs, connects or pays. install_check: before installing an npm or PyPI package, a GitHub repo, a skill or an MCP server, it answers allow / hold / block (known malicious packages from OSV, typosquats of official MCP servers, names that do not exist, install scripts, maintainer changes). check_service: live status, real price and payTo vs the catalogue listing for any x402 endpoint or MCP server, OFAC and stablecoin-freeze screening, uptime, tool-set changes, on-chain payers, an open Trust Score. preflight_payment decides allow / hold / block right before an x402 payment is signed; payment_status prevents paying twice; dispute_evidence builds a signed evidence pack. Every answer is signed into a public transparency log. Free, no account. Claude Code plugin: alalanet-guard.
Let your AI agent pay for APIs and data without handing it your money. In ChatGPT, Claude or Grok, the agent finds paid x402 APIs (with each seller's payout record from x402 Doctor) and asks to pay; you approve and sign each payment in your own wallet: MetaMask or Coinbase Wallet (USDC on Base), Phantom (USDC on Solana) or Xaman (RLUSD on the XRP Ledger). Fizzl checks every payment before you sign and every paid answer for hidden instructions. Fizzl never holds your keys. Free to start.
Arsen is a human risk management platform that enables security teams to assess employee exposure through advanced phishing, voice phishing, and deepfake simulations, and strengthen their resilience with adaptive cybersecurity awareness training. Arsen MCP connects your Arsen platform to your preferred AI assistant, including Claude, ChatGPT, and any MCP-compatible assistant. With Arsen MCP, you can: 1. Build and launch campaigns. Let your AI assistant prepare phishing simulation campaigns and cybersecurity awareness programs, then launch them with your approval. 2. Get actionable insights from your data. Ask questions in plain language and get answers based on your organization's actual data, including campaign results, click, compromise and reporting rates, phishing score trends, coverage, and teams that need attention. 3. Manage multiple client organizations. Give MSSPs the ability to query and work across every client organization they manage, from a single AI assistant. Secure by design. Users authenticate with their Arsen account (SSO and MFA supported), and every request is governed by their existing Arsen permissions.
Shared second brain for any AI with agent permissions
CVE with EPSS and CISA KEV, package risk, software EOL, domain and IP reports, pay per call
Deterministic JSON checks with signed evidence and x402-paid execution
Queries IOCs, vulnerabilities, threat actors and malware correlated from thousands of sources, retaining source-attributed evidence. Collection spans feeds, reports and advisories, social and dark-web monitoring, and Mallory's own sandboxing and internet scanning; a free community tier is available with an account and API key.
Bewary is a scam detection API and MCP server for apps and AI agents: phishing, fraud and threat intelligence lookups an agent runs before it opens a link, calls a number, pays or replies. It checks links and domains (phishing, domain age, lookalike brands), IP addresses, phone numbers (FTC and FCC complaints), SMS short codes, email addresses, crypto wallets (scam reports, OFAC sanctions), IBANs, mobile apps and payment handles. Each answer is a typed verdict (scam, suspicious, safe or unknown) with the facts and reason codes behind it, built from evidence rather than a language model. Watches send an event when a watched domain, number, wallet or brand changes. A free key gets 1,000 credits a month with no card; OAuth sign-in is supported.
Read-only WordPress diagnosis for AI: security, performance, forms and downtime, with evidence.
Search and filter public CVEs and read any of them in full, with CVSS scores, CISA KEV and EPSS, and profile vendors. Read-only, free and open source, no API key needed.
Patchwire is a free, read-only MCP server for security advisories on modern JS, AI and web3 stacks. It reads maintainers' own advisories and vendor security posts every hour, often days before they reach the GitHub Advisory Database, and returns vulnerable ranges, fixed versions per release line and the conditions that make each flaw exploitable. Send package names, never versions. No account, no key.
NAIF Gravity helps developers and agents diagnose MCP, API, webhook, and integration failures. Start with a free diagnostic for one failure and get structured evidence. Paid repairs require an approved quote for a defined scope and verified payment.
ViaSocket is integration and AI infrastructure for developers. Connect 2,300+ apps, build and manage automated workflows, embed AI agents with persistent memory, and add authentication, organisations, and embedded integration UIs to your product through a single MCP server.

Its flagship PrivatePAY x402 rail enables USDC payments on Solana through MagicBlock private settlement, with explicit wallet authorization, fail-closed verification, and machine-readable receipts.
Check before money moves. Lorg Check tells an AI agent, or you, whether a token is a trap or an address is unsafe to pay, on Base and Ethereum. In live tests on new launches it blocked traps that GoPlus and Honeypot.is missed. Call check_token before buying or swapping into a token: it simulates a real buy and sell-back through the token’s own pool, reads what the creator can still do, who can pull the liquidity, and whether the creator was paid by a wallet behind earlier rugs. Call check_address before sending funds: sanctions, scam labels, EIP-7702 sweepers and address-poisoning look-alikes. Every answer is signed and says proceed, limit_exposure or do_not_proceed, with a one-line summary to show the user. Free key by GitHub sign-in, or connect with an API key.
