Automate web navigation for LlamaIndex

Use `create_browser_session` to open the web. The output gives you a direct link to control the browser from your LlamaIndex agents. This lets you feed live DOM data into your vector store. Your index stays current because the agent pulls fresh information every time it runs a query.

Track Browserbase sessions in LlamaIndex

Use `list_browser_sessions` to review what the agent has been doing. It returns a list of sessions, which you can then sort by status. This helps you audit which sessions provided data for your index. You can identify errors quickly if a specific run fails to return expected content.

Clean up browser resources with LlamaIndex

Call `stop_browser_session` to end the connection when the data collection is done. This keeps your account clean and prevents orphaned sessions. LlamaIndex treats this as just another function call. It executes at the end of your pipeline to ensure the remote environment shuts down properly.

Setup guide

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

Common questions about Browserbase MCP in LlamaIndex

The agent uses the CDP URL to browse and extract text. That text is then passed back to your indexer for semantic storage.

It can query the session metadata. You can use the list tool to fetch IDs and check the status of previous runs.

We enforce strict access control via your endpoint token. Your browser session data is encrypted in transit and never shared with other users.

The server handles it for you. If you need a session to persist longer than the default, you handle that through your agent logic.

It handles browser session IDs and CDP WebSocket URLs. None of your personal browsing history or credentials are stored by the server.
