Perplexity

Validate Copy.ai inputs using Pydantic AI.

Your Pydantic AI agent queries `get_workflow_details` over the MCP Server to fetch the input schema of a target Copy.ai pipeline. It uses this schema to build a Pydantic model at runtime, validating all arguments before calling `run_workflow`. If your agent tries to send an invalid parameter to Copy.ai, Pydantic AI throws a validation error immediately. This prevents silent execution failures and keeps your production pipelines clean.

Type-safe workspace and folder navigation.

The Pydantic AI agent uses `list_folders` and `list_workflows` via the MCP to map out your Copy.ai environment. Every folder ID, workflow title, and metadata field returned is validated against strict Pydantic schemas. This guarantees your Pydantic AI code never processes malformed JSON or unexpected null values from the Copy.ai API. If the API response changes, your application fails loudly and predictably.

Brand asset validation and tracking.

Your Pydantic AI agent tracks execution progress by polling `get_run_status` and pulls Copy.ai brand guidelines with `list_brand_assets`. The returned payloads are instantly parsed into typed Python objects. This setup ensures that Copy.ai brand assets and workflow outputs conform to your exact Pydantic AI data models. You can confidently pass these typed outputs to other services in your stack.

Setup guide

Set up Copy.ai 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": {
        "copyai-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Copy.ai MCP in Pydantic AI

The agent calls schema details to retrieve the JSON schema of your workflow. Pydantic AI dynamically constructs a validator to ensure the agent's inputs match this schema before execution.

Pydantic AI will raise a validation error instantly. If brand assets or run status tools return a field that doesn't match the expected type, the framework halts execution to prevent corrupted data from spreading.

Yes. Pydantic AI is model-agnostic, meaning you can connect this MCP Server to local models or commercial LLMs while maintaining strict type safety for all tool calls.

Use the unified toolset class with your Vinkius HTTP endpoint. Pass the toolset directly to your agent constructor to expose tools like execution and folder listing.

Vinkius operates a zero-trust architecture where this MCP Server processes workflow inputs, execution statuses, and folder structures in ephemeral V8 isolates. No data is stored, and your API tokens are encrypted at rest.
