How to Use the LocationIQ MCP in LlamaIndex

Q: Can I cache LocationIQ API outputs in a LlamaIndex vector store?

Yes. You can ingest the JSON outputs from search or reverse directly into Document nodes, embed them, and store them to avoid redundant geocoding costs.

Q: Does the LlamaIndex MCP client support live map generation with LocationIQ?

Yes. The agent calls staticmap to get map URLs, which it can inject directly into the final response text or save as metadata inside your index nodes.

Q: How do I filter which LocationIQ tools are available to LlamaIndex?

Use the allowedtools list when initializing your McpToolSpec to expose only specific endpoints like search or timezone to your agent.

Index LocationIQ spatial data directly into your LlamaIndex vector stores for ground-truth RAG.

Build spatial indexes with LlamaIndex

Store physical address metadata directly in your vector database by indexing outputs from the `reverse` tool. LlamaIndex indexes the raw coordinate matches, storing physical addresses alongside their semantic descriptions in your vector database. This lets your RAG pipeline query past location lookups without repeating API calls. Your agent queries the index first, retrieving cached spatial data before deciding to hit the live API.

Ground agent responses with live LocationIQ maps

Prevent RAG hallucinations by anchoring your LlamaIndex query engine to verified coordinates retrieved via the `nearby` tool. Equipping your LlamaIndex agent with the MCP Server ensures it pulls verified business listings and coordinates directly into its context window. The agent uses `autocomplete` to resolve partial queries, then structures the clean spatial data into your node post-processors. This guarantees that every local recommendation rests on real-world coordinates.

Temporal indexing using the timezone tool

Align indexed document metadata with local schedules by using the `timezone` tool to resolve coordinate offsets. The agent calls this endpoint to resolve the exact local time offset of any coordinate pair before indexing time-sensitive events. This ensures that queries about local business hours or delivery windows map correctly to the target location. You avoid scheduling mismatches by anchoring document metadata to verified temporal zones.

Setup guide

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

Common questions about LocationIQ MCP in LlamaIndex

Yes. You can ingest the JSON outputs from `search` or `reverse` directly into Document nodes, embed them, and store them to avoid redundant geocoding costs.

The FunctionAgent inspects the schemas of your registered LlamaIndex MCP client tools, choosing `directions` for routing questions or `nearby` when searching for local points of interest.

Yes. The agent calls `static_map` to get map URLs, which it can inject directly into the final response text or save as metadata inside your index nodes.

Use the allowed_tools list when initializing your McpToolSpec to expose only specific endpoints like `search` or `timezone` to your agent.

Yes. Your raw coordinates and address queries run through ephemeral V8 isolates. No search history or geographic data is written to persistent storage, protecting user privacy at the network level.
