Semantic search on live data

Transform raw API responses from `get_best_stories` into searchable vectors. Your LlamaIndex agents can now query historical and current tech debates with ease. This creates a grounded knowledge source that updates itself. You stop relying on static documents and start querying the live pulse of the industry.

Automated knowledge ingestion

Set your agent to periodically run `get_updates` and index the changes. Your vector store stays current with the most recent comments and story metadata. It removes the need for manual data syncing. Your index is always ready to answer questions based on the latest happenings on the platform.

Unified data retrieval

Combine `get_item` results with your existing documents to answer complex questions. The agent pulls the missing link from the API whenever your internal data falls short. This makes your RAG application significantly more capable. It bridges the gap between your private files and the public discourse.

Prerequisites

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

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

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

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()

agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Hacker News tools.",
)
response = await agent.run("List recent Hacker News data")
