How to Use the KnoCommerce MCP in Pydantic AI

Q: Can I check the KnoCommerce API status programmatically in Pydantic AI?

Yes. Your agent can call checkknocommerceapistatus to verify the integration health before running complex analysis. This ensures your pipeline doesn't waste LLM tokens when the API is unreachable.

Q: How do I list all available surveys?

Use listsurveys to get a structured list of all post-purchase campaigns. You can then pass these IDs to listsurveyresponses to target your analysis.

Perplexity

Validate customer feedback profiles at runtime

The `get_customer_feedback_profile` tool fetches detailed survey responses and buyer metadata directly into your Python codebase. Pydantic AI validates this incoming data against your defined schemas, preventing silent failures. If a survey response contains unexpected fields, the framework raises a validation error immediately. This ensures your data pipelines only process clean, structured customer feedback.

Parse attribution reports using a type-safe MCP Server

The `get_channel_attribution_report` tool retrieves post-purchase channel metrics from your store. Your agent uses this data to map self-reported customer acquisition channels to actual marketing spend. Because Pydantic AI is model-agnostic, you can use this MCP tool with any LLM provider. The framework guarantees that the structured attribution reports conform to your exact data models before this MCP Server executes.

Inspect survey structures safely

The `list_survey_questions` tool extracts the exact question definitions and response formats for any survey. This allows your agent to dynamically adapt its prompts based on the current questions. Your agent calls `get_survey_details` to verify the survey configuration before pulling responses. This prevents your Pydantic AI pipeline from querying inactive or empty campaigns.

Setup guide

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

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

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