How do I find my DingTalk App Key and Secret?

Log in to the DingTalk Developer Backend, create or select an 'Internal Enterprise Application', and you will find the App Key and App Secret under the 'Credentials' section.

Where can I find the Yida 'App Code'?

Open your Yida application, go to [Settings] → [Deployment and O&M], and you will find the 'App Code' (Application Code) there. It is required for all Yida API calls.

Can I see the approval history of a record?

Yes. Use the `get_instance_timeline` tool with the form instance ID. It will return the full approval history, including who approved it and at what time.

About Yida MCP Server

Empower your AI agent to orchestrate your enterprise operations with Yida, the premier low-code platform under the DingTalk ecosystem. By connecting Yida to your agent, you transform complex form management and data orchestration into a natural conversation. Your agent can instantly list your forms, retrieve field schemas, manage data records (create, update, delete), and even monitor workflow approval timelines without you needing to navigate the complex DingTalk interface. Whether you are managing administrative approvals, inventory tracking, or customized business processes, your agent acts as a real-time operations assistant, keeping your data accurate and your workflows moving.

Pydantic AI validates every Yida tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

What you can do

Form Orchestration — List all accessible forms and retrieve detailed field schemas for your Yida applications.
Data Operations — Manage form instances (records) with full support for creating, listing, and granular updates.
Workflow Monitoring — Check the current status and approval timeline for any workflow instance.
Schema Auditing — Retrieve internal form schemas to understand data structures and field IDs.
User Coordination — Access application user lists to manage assignments and participation effectively.

The Yida MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Yida + Pydantic AI FAQ

Common questions about integrating Yida MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Yida MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
