How to Use the Green Web Check MCP in LlamaIndex

Q: How do I connect Green Web Check to LlamaIndex?

Install llama-index-tools-mcp and initialize the BasicMCPClient with the Vinkius URL. Convert the server to tools using McpToolSpec to expose checkgreenhosting to your LlamaIndex agent.

Q: Can I index Green Web Check outputs for semantic search in LlamaIndex?

Yes, you can run checkgreenhosting on your target domains and load the resulting energy profiles directly into your LlamaIndex vector store as document nodes.

Q: Does it support the LlamaIndex tool filtering system?

Yes, you can use the standard LlamaIndex allowedtools filter to restrict your agent's access, ensuring it only runs checkgreenhosting when sustainability queries are detected.

Index Green Web Check environmental data directly into your LlamaIndex vector stores for carbon-aware RAG search.

Index hosting sustainability data with LlamaIndex

Stop letting your RAG pipeline hallucinate green claims. By integrating `check_green_hosting` with LlamaIndex, this MCP Server pulls real-time energy data for domains and indexes the results directly into your vector database. When users query your knowledge base about vendor sustainability, LlamaIndex pulls from these cached, verified records. Your agent relies on actual API outputs instead of stale training data.

Build a carbon-aware knowledge base

This tool lets you build a searchable index of green-certified digital partners. By wrapping `check_green_hosting` in an `McpToolSpec`, your LlamaIndex agents can query website energy sources and save those facts for future semantic search. The integration is simple. Use the `BasicMCPClient` to connect to Vinkius, convert the server tools to LlamaIndex tools, and feed the green status output straight into your document store.

Ground your RAG queries in verified energy data

Your LlamaIndex agents can now verify green claims on the fly. When a user asks if a specific service is eco-friendly, the agent calls `check_green_hosting` to fetch live data, ensuring your system's answers are grounded in reality. This prevents greenwashing in your enterprise search engines. The tool provides the raw proof, and LlamaIndex structures it into clean, queryable nodes for your LLM to reference.

Setup guide

Set up Green Web Check 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 Green Web Check 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 Green Web Check tools.",
)
response = await agent.run("List recent Green Web Check data")

Install `llama-index-tools-mcp` and initialize the `BasicMCPClient` with the Vinkius URL. Convert the server to tools using `McpToolSpec` to expose `check_green_hosting` to your LlamaIndex agent.

Yes, you can run `check_green_hosting` on your target domains and load the resulting energy profiles directly into your LlamaIndex vector store as document nodes.

Instead of guessing if a host is green, your LlamaIndex agent queries `check_green_hosting` directly. The live API data forces the model to base its answers on actual green energy certifications.

Yes, you can use the standard LlamaIndex `allowed_tools` filter to restrict your agent's access, ensuring it only runs `check_green_hosting` when sustainability queries are detected.

Vinkius executes the query in a secure, zero-trust sandbox. The queried domain strings are sent to the Green Web database to fetch hosting records, but they are never cached or exposed outside the active session.
