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.

When paired with CrewAI, Submail / 赛邮云 becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Submail / 赛邮云 tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

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.

Why Use CrewAI with the Submail / 赛邮云 MCP Server

CrewAI Multi-Agent Orchestration Framework provides unique advantages when paired with Submail / 赛邮云 through the Model Context Protocol.

Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the `mcps` parameter and agents auto-discover every available tool at runtime

Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Submail / 赛邮云 + CrewAI Use Cases

Practical scenarios where CrewAI combined with the Submail / 赛邮云 MCP Server delivers measurable value.

Automated multi-step research: a reconnaissance agent queries Submail / 赛邮云 for raw data, then a second analyst agent cross-references findings and flags anomalies. all without human handoff

Scheduled intelligence reports: set up a crew that periodically queries Submail / 赛邮云, analyzes trends over time, and generates executive briefings in markdown or PDF format

Multi-source enrichment pipelines: chain Submail / 赛邮云 tools with other MCP servers in the same crew, letting agents correlate data across multiple providers in a single workflow

Compliance and audit automation: a compliance agent queries Submail / 赛邮云 against predefined policy rules, generates deviation reports, and routes findings to the appropriate team

Submail / 赛邮云 + CrewAI FAQ

Common questions about integrating Submail / 赛邮云 MCP Server with CrewAI.

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
