Index Exa AI results for semantic retrieval

Run a `search_with_contents` to grab data and pipe it straight into your vector store. Your index grows with live information from the web. This prevents the agent from hallucinating by grounding answers in the text retrieved via `extract_page_content`. It builds a bridge between your documents and the internet.

Deploy the Exa AI MCP Server as a tool spec

Use the tool spec to convert the 12 endpoints into native functions. This makes the Exa AI MCP Server a first-class citizen in your LlamaIndex agent. Call `to_tool_list_async` to load everything. You can then filter available tools to keep your agent focused on specific retrieval tasks like `search_by_category`.

Retrieve highlights with Exa AI and LlamaIndex

Use `get_query_highlights` to pull snippets that matter. These chunks are ready for immediate ingestion into your index. It saves you tokens by avoiding full-page dumps. Your index stays efficient because you only store the most relevant parts of the search results.

Setup guide

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