How to Use the Pinterest Ads MCP in Pydantic AI

Q: How does the Pinterest Ads MCP server ensure type safety in Pydantic AI?

The server defines strict schemas for operations like listpinterestcampaigns which the Pydantic AI framework validates at runtime. If the Pinterest Ads API returns an unexpected type, your Pydantic AI Python code raises a validation error immediately.

Q: How do I configure the Pinterest Ads MCP server in my Pydantic AI project?

You initialize MCPToolset with the Pinterest Ads server's HTTP endpoint and pass it to the toolsets argument of your Pydantic AI Agent. This exposes Pinterest tools like listpinterestpins to your agent with zero manual Pydantic AI schema definitions.

Q: How is my Pinterest Ads audience and analytics data protected in Pydantic AI?

All data passing through Pinterest tools like listpinterestaudiences is processed within isolated, zero-trust V8 sandboxes. Your Pinterest credentials and audience lists are never cached or stored, ensuring complete privacy during Pydantic AI runtime validation.

Enforce type-safe campaign parsing in Pydantic AI

The `get_pinterest_campaign` tool outputs structured Pinterest campaign data that validates against strict Pydantic AI models at runtime. If the Pinterest API returns unexpected null fields, the Pydantic AI execution halts immediately to prevent corruption. This strict validation prevents your Pydantic AI agent from passing corrupt Pinterest budget figures to downstream tools. You avoid silent data corruption when managing Pinterest campaign budgets with Pydantic AI.

Validate ad group structures before running models

The `list_pinterest_ad_groups` tool exposes targeting parameters to ensure they match your Pydantic AI application's schema exactly using this MCP server. The Pydantic AI agent parses the returned Pinterest ad groups and verifies their active status before making decisions. When combined with `list_pinterest_ads`, the Pydantic AI framework guarantees that every Pinterest ad object contains required tracking parameters. Your Pydantic AI models never work with incomplete or dirty Pinterest advertising data.

Track analytics with guaranteed schema compliance

The `get_pinterest_analytics` tool provides raw performance data that your Pydantic AI agent validates against predefined Python classes. You get type-safe access to Pinterest impressions, clicks, and conversion events inside your Pydantic AI application. Using `list_pinterest_audiences` alongside this data allows your Pydantic AI agent to map performance metrics to specific Pinterest audience segments. The entire Pinterest pipeline remains fully typed, preventing runtime crashes in your production Pydantic AI deployment.

Setup guide

Set up Pinterest Ads 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": {
        "pinterest-ads-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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