Type-safe Helpwise tool execution

Every response from the Helpwise MCP Server is validated against Pydantic models. If `list_conversations` returns unexpected data, your Pydantic AI agent halts immediately to prevent errors. You avoid the common pitfalls of unstable API data. Your agent logic stays clean because it only processes data that matches your expected schema.

Reliable contact management

Use `create_contact` to ensure your agent adds new leads to Helpwise using strictly typed fields. Your agent won't hallucinate fields that don't exist in your CRM. This guarantees your contact data remains consistent. Your agent acts as a guardrail, ensuring every new record is formatted correctly before it hits your database.

Automated email responses

Your Pydantic AI agent uses `send_email` to reply to customers with validated content. The tool checks your output against your defined models before dispatching the message. This gives you confidence that your agent isn't sending malformed emails. You maintain control over your outgoing communication while keeping your agent logic agile.

Setup guide

Set up Helpwise 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.
