FlickDirect Inc’s free, read-only movie MCP server. Live service 1.5.11 provides movie and TV facts, cast, available country-specific dates and ratings, production trivia, brief quote excerpts, site-wide news and reviews, CinemaCon reporting, interviews and eligible stored transcripts. Cinema United association and year-round exhibition reporting use articles; CinemaCon remains its separate annual convention. FlickDirect’s independent guide is https://flickdirect.com/cinema-united/; the official association site is https://cinemaunited.org/. Find published podcast shows and episodes, including bounded FlickRadio archive matching. Recent uploads from three verified FlickDirect channels retain healthy-feed results when another feed times out, with incomplete coverage explicitly reported. Streaming, soundtrack/player and published Amazon and Apple destinations remain supported. Retailer listings and daily deals are no longer supported. Longer-title recovery preserves original title words and requested year/media filters. The tools are search_flickdirect_content and get_flickdirect_movie_details. Cached search_fdmd and get_fdmd_movie calls remain compatible at the unchanged endpoint. Results retain canonical source links and distinguish missing matches, unavailable sources and ambiguity. Fetch time does not prove upstream currentness. No full articles, reviews, transcripts, scripts or photographs. Playback and tool selection depend on the AI host. Private request diagnostics expire within seven days. No FlickDirect account or API key is required.
WHOIS, RDAP, DNS, IP / ASN / CIDR and Web3 name (ENS, Unstoppable, Handshake) lookups. No API key.
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.
