Key Capabilities
Manage User Identity with the MCP Server
You can initiate onboarding and identity checks directly using `register_shangqian_user` and `verify_identity_v2`. This ensures your agent confirms user legitimacy before any sensitive document handling begins. Your AI client uses these tools to confirm a user's credentials against ShangQian / 上上签 (BestSign)'s system. It handles the full identity verification flow, making sure the signer is who they claim to be.
Drafting Contracts with Vercel AI SDK
Start by uploading standard agreements using `upload_shangqian_template`. Once a template exists, you call `create_shangqian_contract` to generate the specific contract instance. This gives your user flow immediate access to necessary documentation. The system provides status updates via `get_contract_details`, letting your agent confirm if the document is ready for review or signature. You can then use `get_contract_download` to retrieve the final file.
Executing Signatures with MCP Server
When it's time to sign, you simply call `sign_contract_now`. The agent sends the necessary parameters and the contract is executed via ShangQian / 上上签 (BestSign). It’s a single action that completes the entire signing process. To guarantee authenticity, your client can pull the required cryptographic proof using `get_user_certificate`. This step confirms the signer's identity right at the moment of signature.
