Stdio MCP bridge for the hosted OpenRegistry service
Stdio MCP bridge for the hosted OpenRegistry service. The openregistry mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 8 defined tools rather than through you.
Real-time direct access to unmodified data and raw filings of 30 official government registries via MCP.
Everything the assistant can do here goes through one of these:
Coverage — 30 national registriesAuthentication — OAuth 2.1 + DCRError — ActionChatGPT — Plus / Pro / Business / Enterprise / Education plans only (Free tier doesn't expose Developer Mode)Perplexity — Pro / Max / Enterprise plans only. Settings → Connectors → Add custom remote connector → paste the URL → choose OAuth. Works in regular chat, theCursor — The Cursor tool exposed by this serverCline — Settings → Cline → MCP Servers → Edit settings → paste into cline_mcp_settings.json:Windsurf — Cascade panel → hammer icon (🔨) → Configure opens ~/.codeium/windsurf/mcp_config.json. Add this block (note Windsurf uses serverUrl, not url)Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Plenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Openregistry's toolset — Coverage, Authentication, Error and 5 more — is a fair guide to whether it matches your workflow. It is maintained by sophymarine; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
