How to Use the Colossyan MCP in Pydantic AI

Q: How do I add Colossyan to my Pydantic AI agent?

Initialize MCPToolset with your Vinkius HTTP endpoint. Pass the toolset into your Pydantic AI Agent constructor to give your model validated access to all ten Colossyan tools.

Q: Can Pydantic AI validate Colossyan templates before rendering?

Yes. Your Pydantic AI agent calls generatefromtemplate using strictly typed arguments, ensuring that all required Colossyan template variables are present.

Build type-safe video workflows using Pydantic AI to validate Colossyan video schemas before they render.

Type-Safe Video Generation

`generate_video` ensures that your Pydantic AI agent validates the entire JSON Colossyan video descriptor against strict Python schemas before sending it to the server. If the Pydantic AI agent attempts to pass an invalid Colossyan layout or missing field, the execution fails immediately. This strict checking prevents wasted Colossyan API credits on malformed video requests. Your Pydantic AI agent can safely monitor the rendering process using `get_job_status` knowing the input data was completely accurate.

Pydantic AI Avatar and Voice Auditing

`list_actors` allows your Pydantic AI agent to fetch all available Colossyan workspace avatars and validate their IDs against your application's internal models. This prevents your Pydantic AI agent from referencing non-existent Colossyan actors during video generation steps. The same strict type-safety applies to Colossyan audio assets. Your Pydantic AI agent queries `list_voices` to ensure the selected voice matches your strict locale requirements, failing loudly if the Colossyan API returns an unexpected voice format.

Validated Draft Creation

`generate_draft` lets your Pydantic AI agent convert raw markdown or text into structured Colossyan drafts while enforcing runtime types. The Pydantic AI framework guarantees that the text blocks and scenes match the exact structure Colossyan expects. If a Colossyan draft contains errors, the Pydantic AI agent uses `delete_video` or `delete_job` to clean up the workspace. This keeps your Colossyan video production pipeline free of broken or incomplete drafts.

Setup guide

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

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

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

Common questions about Colossyan MCP in Pydantic AI

Initialize `MCPToolset` with your Vinkius HTTP endpoint. Pass the toolset into your Pydantic AI `Agent` constructor to give your model validated access to all ten Colossyan tools.

The Pydantic AI framework raises a validation error immediately. This prevents your agent from continuing with corrupted Colossyan video metadata or broken job links.

Yes. Your Pydantic AI agent calls `generate_from_template` using strictly typed arguments, ensuring that all required Colossyan template variables are present.

No. Vinkius hosts the server externally, so you only need to provide the secure HTTP transport URL to your Pydantic AI toolset.

All Colossyan API keys and job status payloads are handled in memory within the secure Vinkius V8 sandbox. Your sensitive Colossyan video metadata and account credentials are encrypted in transit and never persisted on any external disk.
