Perplexity

Type-safe Meta Ads performance monitoring

Every response from `get_campaign_insights` is checked against your Pydantic models. If the API returns unexpected values, your agent stops immediately to prevent bad data from causing issues. This approach ensures that your agent only acts on confirmed, valid data. It removes the risk of hallucinated fields during your ad optimization tasks.

Strict control of Meta Ads campaigns

Use `pause_campaign` and `activate_campaign` within a validated execution flow. Pydantic AI verifies the action parameters before the MCP Server submits them to the API. This prevents your agent from sending malformed requests to your ad account. You get a clear log of every action, backed by strict schema validation.

Discover assets with the MCP Server

Retrieve your account structure using `list_campaigns`, `list_ad_sets`, and `list_ads`. Your agent processes these lists while maintaining strict data integrity. When your agent calls `list_creatives` or `list_audiences`, the results are parsed directly into your defined objects. This keeps your code clean and free of manual data transformation logic.

Setup guide

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

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

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

Common questions about Meta Ads MCP in Pydantic AI

The framework matches the JSON output from the MCP Server against your Pydantic models. Any deviation triggers an immediate validation error, keeping your agent logic safe.

Yes, you define the expected schema, and the server response is forced to conform. It eliminates silent data corruption during your agent's analysis.

It supports both SSE and HTTP transports. You simply choose the one that fits your infrastructure, and the toolset handles the rest.

Because the agent fails loudly on validation errors, you can catch them in your standard exception handlers. You will always know exactly why an action failed.

They are handled by the secure Vinkius and injected via your endpoint token. Your code never sees the raw credentials, ensuring they stay secure throughout the validation process.
