How to Use the Hyperbrowser (Web Infra for AI) MCP in LlamaIndex

Q: Can LlamaIndex agents execute custom JavaScript using Hyperbrowser (Web Infra for AI)?

Yes, your LlamaIndex agent can use runscript to interact with dynamic page elements or bypass complex paywalls. This allows the agent to extract deep page content that isn't accessible via simple GET requests.

Q: How does Hyperbrowser (Web Infra for AI) prevent LlamaIndex from indexing duplicate session data?

Each session created with createsession is isolated. You control exactly when to trigger stopsession, ensuring your LlamaIndex reader only digests unique, fresh page snapshots.

Q: Can I capture visual context for a LlamaIndex multimodal index?

Yes, use pagescreenshot to retrieve image metadata or URLs of the rendered pages. You can then feed these images directly into LlamaIndex MultiModalVectorStoreIndex via the MCP connection.

Index live web data directly into LlamaIndex vector stores using Hyperbrowser cloud browser sessions.

Perplexity

Semantic indexing of live web pages

The `page_content` tool grabs the raw, fully-rendered HTML of dynamic websites so LlamaIndex can parse and chunk it for your vector index. Because modern web apps rely on heavy client-side rendering, this tool ensures your RAG pipeline indexes actual rendered text rather than empty JS templates. Your LlamaIndex ingestion pipeline can use these clean documents to build a highly accurate knowledge base. By running this process through an MCP Server, your index stays grounded in real-time web data instead of outdated static files.

LlamaIndex RAG with structured MCP Server extraction

The `extract_data` tool bypasses standard HTML chunking by using LLM power to pull structured JSON directly from web pages. This lets your LlamaIndex query engine retrieve clean, schema-conforming node metadata instead of raw, noisy text blocks. You can feed this structured data directly into a LlamaIndex Property Graph Index. This connects extracted web entities and their relationships, giving your agent a highly structured map of the scraped web target.

Async scraping for large-scale knowledge ingestion

The `start_scrape` tool triggers background scraping jobs for massive web sources that would otherwise time out standard LlamaIndex readers. Your indexer handles these jobs asynchronously, polling `get_scrape_job` to fetch the completed payloads when they are ready. This decoupled architecture keeps your ingestion pipeline fast and responsive. While waiting for background jobs, you can use `list_sessions` and `get_session` to monitor active browser runs and track ingestion health.

Setup guide

Set up Hyperbrowser (Web Infra for AI) 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 Hyperbrowser (Web Infra for AI) 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 Hyperbrowser (Web Infra for AI) tools.",
)
response = await agent.run("List recent Hyperbrowser (Web Infra for AI) data")
