How to Use the Upstash MCP in LlamaIndex

Q: How do I ensure the data indexed by Upstash and LlamaIndex is always up-to-date?

You must combine set operations with expire. By setting a TTL, you guarantee that old knowledge records get purged before they can skew your vector search results.

Q: Is there an efficient way to retrieve all indexed data points using Upstash and LlamaIndex?

You use the hgetall command. This pulls every field and value from a single hash key, giving your agent a complete object snapshot that can be fed into the next indexing step.

Q: What if I need to query data that was added in a specific sequence using Upstash and LlamaIndex?

Use Redis lists. By appending events with rpush, you create an ordered record that can be easily retrieved by range (lrange), maintaining the chronological context for your knowledge index.

Q: How do I check if a key exists in Upstash for LlamaIndex integration?

Use exists. It's lightweight and only checks presence, avoiding unnecessary network calls or value retrievals. This saves time when determining if data needs to be indexed at all.

Perplexity

Store foundational facts for the knowledge base

When your agent gathers new information, you write it to the MCP Server. Use `set` or `hset` to store key-value pairs that become searchable documents in your index. The data needs structure; these operations let you build out fact records easily.

Manage knowledge freshness with Upstash and LlamaIndex

Knowledge bases get stale fast. Use the `expire` tool to automatically delete keys after a set time period. This ensures that when your RAG application queries for information, it only pulls data you know is current.

Build historical activity logs with MCP Server

To provide context across sessions, use Redis lists. You can append chronological entries using `rpush` to build an immutable log of events. LlamaIndex then indexes these logs so you can query past API results.

Setup guide

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