How to Use the GPTZero MCP in LlamaIndex

Q: Can I store GPTZero scores as metadata in LlamaIndex?

Yes, you can run detectaiintext during ingestion and attach the resulting probability scores directly to your LlamaIndex document nodes. This lets you filter your vector search by human-authored content.

Q: How does LlamaIndex handle GPTZero model updates?

Your ingestion agent can call listavailablemodels to check for updated detection engines. You can then configure your LlamaIndex tools to target the most accurate model version dynamically.

Q: How do I verify my GPTZero account status inside LlamaIndex?

You can have your agent call getcurrentuser to retrieve your profile details and verify your active subscription. This helps you debug access issues directly from your LlamaIndex terminal.

Q: Is the document text sent from LlamaIndex to GPTZero secure?

Yes, all text passages analyzed by detectaiintext run through isolated, ephemeral V8 containers managed by the Vinkius MCP platform. Your data is never cached, stored, or exposed to external networks during the scanning process.

Index GPTZero detection scores directly into your LlamaIndex vector stores to filter out AI-generated documents.

Perplexity

Build clean knowledge bases for LlamaIndex RAG

The `detect_ai_in_text` tool scans raw documents before they enter your LlamaIndex vector store. Use this MCP Server to analyze incoming files, ensuring your index contains only verified human writing. The tool returns precise sentence-level highlights. Your indexer can store these scores as metadata, allowing your query engine to filter out machine-written passages during retrieval.

Interpret detection metrics inside your index queries

The `get_interpretation_guide` tool helps your LlamaIndex agent analyze borderline retrieval scores. When your pipeline pulls a document with a borderline score, it can call this tool to make sure you are not making binary assumptions about text origin. If the agent suspects a false positive, it uses `submit_prediction_feedback` to correct the score. This feedback is logged alongside your document metadata for future audit trails.

Monitor indexer API health and quotas automatically

The `get_api_quotas` tool lets your LlamaIndex ingest pipeline check credit balances before starting a batch. Running large-scale RAG pipelines on this MCP setup can consume API credits fast, so checking first is critical. The pipeline can also run `check_api_health` to verify the connection before parsing thousands of documents. If the endpoint is down, LlamaIndex pauses ingestion gracefully instead of throwing unhandled errors.

Setup guide

Set up GPTZero MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all GPTZero MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to GPTZero tools.",
)
response = await agent.run("List recent GPTZero data")
