Perplexity

Type-safe record operations

Use `create_record` and `update_record` knowing that Pydantic AI validates every field. If the server returns weird data, you get an immediate error instead of silent corruption. This prevents bad data from hitting your forms. Your agent catches schema mismatches before they cause downstream issues.

Strict schema enforcement

Fetch your structure with `get_form_schema` and define models that match. This ensures your agent strictly follows the rules defined in your forms. Use `list_forms` to verify your target before execution. Your agent refuses to perform actions that don't pass your type definitions.

Validated workflow monitoring

Get status updates via `get_workflow_status` and validate them against your Pydantic models. You get clean, typed data in every response. Use `list_address_book` to pull user lists for your agent's decision logic. Everything remains validated and consistent.

Setup guide

Set up Jiandaoyun 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": {
        "jiandaoyun-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Jiandaoyun MCP in Pydantic AI

It provides runtime validation. If a Jiandaoyun API response doesn't match your expected model, the agent fails safely instead of continuing with bad data.

Import the MCPToolset and point it to the Vinkius server URL. Your agents will inherit the tool definitions automatically.

Yes, `delete_record` is fully supported. You can wrap it in an agent function that requires confirmation before executing the call.

Because the framework is model-agnostic, you can swap between models without changing your tool definitions or validation logic.

We secure your data through ephemeral connections. Your records are only accessed via the validated tools you define, ensuring no unauthorized data exposure.
