How do I find my Submail AppID and AppKey?

Log in to the [Submail Management Console](https://www.mysubmail.com/), navigate to the relevant project type (SMS, Mail, or Voice) and look for the 'AppID' and 'AppKey' in the project settings or credentials section.

Does this server handle MD5 signatures?

Yes! The server automatically calculates the required MD5 signature for every request using your provided AppKey, ensuring secure authorized communication with Submail APIs.

Can I send template-based SMS?

Yes! Use the `send_template_sms` tool. You will need the Project ID of your template and a JSON string containing the variables defined in that template.

About Submail / 赛邮云 MCP Server

Empower your AI agent to orchestrate your multi-channel communications with Submail (赛邮云), the premier cloud communication platform in China. By connecting Submail to your agent, you transform complex SMS broadcasting, HTML email sending, and voice-to-speech notifications into a natural conversation. Your agent can instantly send transactional messages, calculate remaining credit balances, and coordinate verify-by-voice calls without you ever needing to navigate the comprehensive Submail Management Console. Whether you are managing user alerts or coordinating automated verification flows, your agent acts as a real-time communication coordinator, providing accurate and fast results from a single, authorized source.

Pydantic AI validates every Submail / 赛邮云 tool response against typed schemas, catching data inconsistencies at build time. Connect 8 tools through the 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

Multi-Channel Orchestration — Send SMS, HTML emails, and voice notifications from a single agent interface.
Template Automation — Utilize project-based templates (XSend) with custom variables for dynamic messaging.
Verification Management — Trigger voice verification codes and monitor real-time delivery status.
Credit Auditing — Query remaining balances for SMS, Mail, and Voice credits to ensure service continuity.
Operational Monitoring — Verify API connectivity and AppID configurations to maintain system-wide health.

The Submail / 赛邮云 MCP Server exposes 8 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.

Submail / 赛邮云 + Pydantic AI FAQ

Common questions about integrating Submail / 赛邮云 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 Submail / 赛邮云 MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
