yuandian_dsh_plugin

A recurring friction when using AI assistants for legal research is that PRC statutes, court opinions, corporate registry data, and securities-compliance materials live on separate platforms and cannot be queried in a single conversational thread. huayu-yuandian-legal-data bridges the Yuandian (Chineselaw) open-platform aggregated MCP endpoint into DeepSeek Harness, letting you retrieve mainland-China regulations and their validity status, judgment documents and analogous cases, corporate business-registration, risk, litigation and IP details, as well as securities regulatory cases and listed-company announcements—all within one session, without switching browsers or reconciling sources by hand.

The plugin ships four official Yuandian skills for statute search, case search, corporate search, and securities compliance, backed by a full MCP tool bridge with bounded pagination, live tool-list refresh, exponential-backoff reconnection, call timeout and cancellation. Authentication supports both OAuth (Authorization Code + PKCE S256 with dynamic client registration and refresh-token support) and a static API key, switchable at any time from the settings page. Installation and first load stay in an unauthenticated idle state—no browser opens, no network call fires—until you explicitly initiate a connection. Non-loopback endpoints are forced over HTTPS, credentials are written to a local 0600-permission file, and neither API keys nor tokens ever appear in logs.

If you are a mainland-China practicing lawyer, in-house counsel, compliance officer, or legal researcher who wants to fold the Yuandian data source into a daily AI-assisted workflow and drive multi-turn legal research in natural language, this plugin offers a zero-backend, ready-to-use integration path. Retrieved legal data should still be verified against its source, currency, and scope of applicability; it does not constitute formal legal advice.
