Built-in capabilities (10)
The template must be approved before it can be used. Template content should include variable placeholders like {1}, {2} for dynamic content. Approval typically takes a few minutes to hours. Create a new SMS template in Chuanglan 253

Use this to monitor available messaging capacity before sending campaigns. Check SMS account balance on Chuanglan 253
This is useful for checking the status of bulk SMS campaigns where multiple messages were sent with the same tracking identifier. Query delivery status for a batch of SMS messages
Returns whether the message was delivered, is pending, or failed, along with timestamps. Query delivery status of a specific SMS message
Templates are pre-approved message formats that can be used for sending. Each template has an ID, name, content, and approval status. List all SMS templates in your Chuanglan account
The phone number must include the country code without 00 prefix (e.g., 5511999999999 for Brazil). This endpoint uses the international gateway and requires proper permissions. Send an international SMS message via Chuanglan 253
The phone number must include the country code (e.g., 86 for China, 55 for Brazil). For Chinese domestic SMS, the message content must start with a signature in brackets like [YourBrand]. Returns submission status and message ID. Send an SMS message via Chuanglan 253 platform
This is commonly used for 1-click login flows, phone number verification, and two-factor authentication. The message format should follow the template registered in your account. Phone number must include country code. Send a verification code SMS (1-click login style)
This is an alternative to SMS verification, useful when SMS delivery fails or for enhanced security. The code will be spoken in the call. Send a voice verification call with a code
Why CrewAI?
When paired with CrewAI, Chuanglan 253 becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Chuanglan 253 tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
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
mcpsparameter 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

Frequently asked questions
How do I format phone numbers for sending SMS?
Phone numbers must include the country code without the 00 prefix. For example: China uses 86 (e.g., 8615800000000), Brazil uses 55 (e.g., 5511999999999), US uses 1 (e.g., 12025551234). The number should be 5-20 digits total. For Chinese domestic SMS, the message must start with a registered signature like [YourBrand].
What's the difference between send_sms and send_international_sms tools?
The send_sms tool uses the standard SMS gateway (smssh.253.com) optimized for Chinese domestic messages and requires pre-registered templates and signatures. The send_international_sms tool uses the international gateway (intapi.253.com) for global delivery outside China, which supports SenderId and doesn't require Chinese-style signatures. International SMS permissions must be separately enabled in your account.
How does the MD5 signature authentication work?
The Chuanglan API uses MD5 signature authentication for security. Your password is NEVER sent in the request body. Instead, it's combined with the request parameters and timestamp (nonce), then hashed with MD5 to generate a sign header. The server validates this signature to ensure request integrity. The framework handles all signature generation automatically — you only need to provide your account and password.
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.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
