How to Use the AskHandle MCP in Pydantic AI

Q: How do I register the AskHandle MCP Server in Pydantic AI?

Install pydantic-ai-slimmcp, then initialize MCPToolset with your Vinkius HTTP endpoint. Pass this toolset directly into your Agent constructor to expose the AskHandle API.

Q: What happens if AskHandle returns incomplete data to Pydantic AI?

The framework raises a ValidationError at runtime. This prevents your agent from making decisions based on malformed payloads when calling tools like retrieveroom.

Q: Is the older MCPServerHTTP class still supported?

No. Pydantic AI has deprecated MCPServerHTTP. You should use the unified MCPToolset class pointing to your external Vinkius server URL instead.

Validate AskHandle lead schemas with Pydantic AI

The `retrieve_lead` tool fetches complete profile details for any contact, which Pydantic AI instantly validates against your local Python schemas. If the AskHandle API returns an unexpected null value or an altered field type, the framework raises a validation error immediately. This strict runtime checking prevents corrupt data from polluting your downstream systems. When creating new contacts, the agent uses `create_lead` only after verifying the local Pydantic model is perfectly populated.

Run strict type checks on this MCP Server

The `list_rooms` tool retrieves your active chat channels, returning a structured payload that your agent parses with absolute type safety. Because Pydantic AI is model-agnostic, you can use this toolset with GPT-4o, Claude, or local LLMs. Your agent can then inspect a specific channel using `retrieve_room`. If the room's data structure doesn't match your defined Python classes, the execution halts before your code can crash silently.

Manage support webhooks without silent failures

The `list_webhooks` tool returns all active event subscriptions, allowing your agent to audit your integration endpoints. Pydantic AI validates the URL formats and event types returned by the API. If an unauthorized or broken webhook is found, the agent calls `delete_webhook` to tear it down. The entire flow runs via the unified `MCPToolset` class, keeping your codebase clean and modern.

Setup guide

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

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

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