How to Use the Fxiaoke MCP in Pydantic AI

Q: How do I connect Fxiaoke to Pydantic AI?

Install pydantic-ai-slimmcp. Define your connection using MCPToolset with your HTTP endpoint. Pass that toolset array directly to your Agent instance.

Q: Can Pydantic AI handle the complex JSON from Fxiaoke approvals?

Yes. The getapprovaldetails tool returns deep nested structures. Pydantic AI parses these payloads and validates them against your defined models before the agent acts on them.

Bring strict type safety to your Fxiaoke CRM integrations with Pydantic AI and stop silent data corruption.

Type-Safe Fxiaoke MCP Server Operations

The Fxiaoke MCP Server validates every single response at runtime to prevent hallucinated fields when writing to your enterprise CRM. You cannot afford bad data in your sales pipeline. If the API returns a weird format, the agent throws a loud validation error immediately. This means when you call `create_opportunity` or `create_lead`, the payload matches your exact Pydantic models. Zero silent failures occur. You keep garbage data from polluting your Chinese sales operations.

Model-Agnostic Fxiaoke Integration

The `list_accounts` and `list_contacts` endpoints work exactly the same way regardless of which LLM powers your Pydantic reasoning engine. Lock-in is a massive liability. Because this framework is model-agnostic, you swap between Anthropic, OpenAI, or local models instantly. You write the agent logic once. The tools return consistent, typed JSON every time. If OpenAI goes down, you route the Fxiaoke queries to Gemini without rewriting a single line of your tool definitions.

Audit Your Sales Activity

Your agent can pull `list_sales_tasks` and `list_users` to generate strict, typed reports on rep activity. Managers need raw facts, not summaries. The agent extracts exact timestamps and task statuses from the CRM. Need to know why a deal is stuck? The agent hits `list_approvals` followed by `get_approval_details`. It parses the exact status and approver name, mapping the messy Fxiaoke JSON into clean Python objects you can actually use.

Setup guide

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

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

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

Common questions about Fxiaoke MCP in Pydantic AI

Install `pydantic-ai-slim[mcp]`. Define your connection using `MCPToolset` with your HTTP endpoint. Pass that toolset array directly to your Agent instance.

Standard clients require you to write and maintain dozens of API wrappers manually. The MCP integration gives your agent native access to `list_leads` and `create_lead` while Pydantic enforces the schema boundaries.

Yes. The `get_approval_details` tool returns deep nested structures. Pydantic AI parses these payloads and validates them against your defined models before the agent acts on them.

Yes. You can use either Streamable HTTP or SSE transports depending on your infrastructure. The `MCPToolset` handles the underlying connection automatically.

The connection is completely ephemeral. When your agent requests employee details via `list_users`, the names and email addresses are processed in memory and the secure tunnel collapses the moment the script exits.
