Perplexity

Type-safe conversation processing

Every response from `get_conversation_details` is validated against your Pydantic models at runtime. If the API returns junk, the agent stops immediately. This prevents your Pydantic AI agent from hallucinating fields or processing corrupted data. You get exact, reliable objects for every chat session.

Validated agent and group lookups

Your agent uses `list_support_agents` to retrieve staff data. Each agent profile is strictly typed, so your logic works every time. It eliminates the risk of silent failures when querying `list_agent_groups`. Your Pydantic AI implementation knows exactly what the data structure looks like before it processes the result.

Reliable messaging operations

Send messages using `send_chat_message` with full schema validation. Your agent ensures the conversation ID and payload meet all requirements before calling the API. This keeps your Pydantic AI agent stable. You avoid runtime errors by catching invalid requests before they ever hit the Freshchat servers.

Setup guide

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

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

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