How to Use the GPTZero MCP in Pydantic AI

Q: How do I register the GPTZero MCP server in Pydantic AI?

Use the MCPToolset constructor with your Vinkius HTTP URL to load the MCP tools. Then, pass the toolset to your agent's toolsets argument during initialization.

Q: Does Pydantic AI validate the GPTZero model list?

Yes, when your agent calls listavailablemodels, the response is parsed through Pydantic models to ensure the returned versions match your expected schema. This prevents errors when choosing between model versions.

Q: How does Pydantic AI handle GPTZero rate limits?

The agent queries getusagepolicy to retrieve rate limits as validated Python objects. You can use these values to configure backoff strategies and avoid throwing API errors.

Validate detection data in Pydantic AI

The `detect_ai_in_text` tool returns structured prediction data that your Pydantic AI agent validates against strict Python schemas at runtime to ensure compatibility with this MCP Server. If the API response deviates from the expected format, your application fails immediately instead of passing corrupted metrics down the line. This strict validation guarantees that your confidence scores, sentence highlights, and perplexity metrics are always clean and usable. You eliminate silent failures in your automated content moderation pipelines.

Check quotas securely with Pydantic AI

The `get_api_quotas` tool feeds remaining credit counts directly into your Pydantic AI agent using type-safe models. The agent verifies the integer values of your remaining requests before initiating any text analysis. This prevents runtime type errors when parsing API responses. Your agent can confidently make branching decisions, such as pausing the pipeline or switching to a lighter model, based on highly reliable quota data.

Submit verified feedback using this MCP Server

The `submit_prediction_feedback` tool allows your Pydantic AI agent to send structured corrections back to the platform with guaranteed payload alignment. Every feedback submission is verified against the official schema before the HTTP request is fired. This means your agent never sends malformed feedback objects that silently fail on the server side. You maintain a highly reliable feedback loop that helps improve your team's detection accuracy over time.

Setup guide

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

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

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

Common questions about GPTZero MCP in Pydantic AI

Use the `MCPToolset` constructor with your Vinkius HTTP URL to load the MCP tools. Then, pass the toolset to your agent's `toolsets` argument during initialization.

Yes, when your agent calls `list_available_models`, the response is parsed through Pydantic models to ensure the returned versions match your expected schema. This prevents errors when choosing between model versions.

Yes, the framework supports async execution out of the box. Your agent can run multiple `detect_ai_in_text` checks in parallel without blocking your main application loop.

The agent queries `get_usage_policy` to retrieve rate limits as validated Python objects. You can use these values to configure backoff strategies and avoid throwing API errors.

All text payloads and prediction queries are transmitted over secure TLS and processed in isolated, ephemeral environments. No data is stored, shared, or utilized for training purposes, keeping your proprietary content safe.
