Type-safe asset generation for Pydantic AI

Define your schema and let Pydantic AI validate every response from `create_text_to_3d_preview`. If the API returns unexpected fields, the agent catches it immediately. This prevents your agent from passing malformed data to your downstream rendering pipelines. You get predictable, validated results every time.

Validated retexturing for Pydantic AI

Apply `create_retexture` to existing models while ensuring the output aligns with your required data model. Pydantic AI enforces the structure of the task request. This keeps your agent logic robust. You avoid silent failures caused by API changes or unexpected model responses.

Task management inside Pydantic AI

Call `list_text_to_3d_tasks` to inspect the status of your generation jobs. Pydantic AI ensures the returned list matches your expected object structure. You can easily filter or sort your tasks based on validated data. This makes it simple to manage large volumes of generated assets without bugs.

Setup guide

Set up Meshy (3D 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": {
        "meshy-3d-ai-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Meshy (3D AI) tools.",
)

result = await agent.run("List recent Meshy (3D AI) transactions")
print(result.output)

Common questions about Meshy (3D AI) MCP in Pydantic AI

The MCP toolset automatically maps the server response to your Pydantic models. Validation happens at runtime, stopping the agent if data is incorrect.

Yes. Pydantic AI is model-agnostic, meaning you can swap the underlying model while keeping the same MCP tool integration.

The combination provides high reliability because the toolset forces strict schema adherence on all API interactions.

You can define your own models to represent the API output. This gives you full control over how your agent interprets the generated 3D data.

Your API key is handled by the server environment variables. The agent only interacts with the server, keeping your sensitive auth data out of the application code.
