How do I find my eSign App ID and Secret?

Log in to the [eSign Open Platform](https://open.esign.cn/), create a new application, and you will find your App ID and App Secret in the application credentials section.

Can I retrieve the signing URL for a participant?

Yes. Use the `get_execute_url` tool with the flow ID and the signer's account ID. Your agent will retrieve the unique URL where the participant can perform the signature.

Is it possible to download the signed documents?

Yes! Once a sign flow is completed, you can use the `download_docs` tool to retrieve temporary download links for all documents included in that flow.

eSign (e签宝) + Cursor FAQ

Common questions about integrating eSign (e签宝) MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
