Check before your agent installs, connects or pays. install_check: before installing an npm or PyPI package, a GitHub repo, a skill, an editor extension 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_repo_config: before opening a repository someone sent you, it reads its agent configuration (MCP servers, hooks, editor tasks, instruction files) and runs nothing. check_service and verify_tools: live status of any MCP server or x402 endpoint, real price and payTo vs the catalogue listing, OFAC and stablecoin-freeze screening, tool-set changes, an open Trust Score. find_service finds working services. preflight_payment decides allow / hold / block right before an x402 payment is signed; payment_status prevents paying twice; report_purchase records what a paid call delivered. Verdicts are signed into a public transparency log. Free, no account.
