How to Use the Chuanglan 253 MCP in Pydantic AI

Q: How do I configure Chuanglan 253 with Pydantic AI?

Install pydantic-ai-slimmcp. Initialize MCPToolset with your HTTP endpoint and pass it to your Agent's toolsets list. The older MCPServerHTTP class is deprecated.

Q: Can Pydantic AI validate Chuanglan 253 voice codes?

Yes. When the agent triggers sendvoiceverification, your Pydantic models ensure the spoken code matches your exact numeric schema before dialing.

Q: How does Pydantic AI handle Chuanglan 253 template creation?

The agent drafts the format and calls createtemplate. Your schema catches any missing dynamic variables before the request ever reaches the approval queue.

Q: Does Pydantic AI check Chuanglan 253 account info?

It reads your setup perfectly. The agent uses getaccountinfo and validates the returned configuration against your expected production state.

Type-safe Chuanglan 253 integration for Pydantic AI to validate every SMS payload before it hits the carrier network.

Perplexity

Type-Safe MCP Server Messaging

Silent API failures ruin production systems. When your agent calls `send_sms` or `send_international_sms`, Pydantic AI validates the exact phone number format and country code against your strict schemas. If the model hallucinates a bad prefix, the system throws a loud validation error immediately. You get identical guarantees for verification flows. Executing `send_verification_sms` forces the agent to map the exact 1-click login template variables correctly. It refuses to send malformed texts to your users.

Strict Status Parsing

Carrier delivery reports are notoriously messy. Your agent runs `query_sms_status` or `query_batch_sms_status` and Pydantic maps the raw timestamps and pending flags into clean Python objects. There's no guessing if a message arrived. The framework forces the LLM to process the exact delivery state, ensuring your database updates reflect reality rather than a hallucinated success message.

Template and Balance Validation

Drafted messages must match carrier rules exactly. By invoking `query_template_list`, your system pulls down the approved formats. Pydantic ensures the agent only injects data into valid {1} or {2} placeholders. Before any campaign starts, the agent checks `get_sms_balance`. If the returned integer falls below your predefined Pydantic threshold, the workflow halts. You never risk running a massive script on an empty wallet.

Setup guide

Set up Chuanglan 253 MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "chuanglan-253-1-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Chuanglan 253 tools.",
)

result = await agent.run("List recent Chuanglan 253 transactions")
print(result.output)
