How to Use the ExchangeRate- MCP in LlamaIndex

Q: How do I connect ExchangeRate- to LlamaIndex?

Install the LlamaIndex MCP adapter and initialize the BasicMCPClient with your Vinkius server URL. Wrap it in McpToolSpec and convert it to a tool list using totoollistasync(). Then, pass those tools directly to your LlamaIndex agent.

Q: Can LlamaIndex cache ExchangeRate- API responses?

Yes, you can index the outputs of tools like getlatestrates directly into your vector store. This lets you serve subsequent search queries locally, saving your API quota for when you actually need fresh data.

Q: How does the ExchangeRate- agent handle API limits in LlamaIndex?

You can configure your LlamaIndex agent to check getquota before executing heavy batch queries. This prevents your index ingestion pipelines from hitting hard rate limits and failing mid-run.

Q: Can I filter which ExchangeRate- tools LlamaIndex can access?

You can use the allowedtools filter when setting up your tool specification. This lets you restrict your LlamaIndex agent to basic tools like getpairconversion while blocking heavier analytical operations.

Index live currency data into your LlamaIndex vector store to ground your financial RAG applications in real rates.

Ground LlamaIndex RAG queries with this MCP Server

Stop your LlamaIndex agents from hallucinating financial conversions. By exposing `get_pair_conversion` to your agent, it pulls exact, real-time rates rather than guessing or using outdated training data. The agent reads live numbers and inserts them directly into the query context. This ensures that any financial advice or cost calculation generated by your RAG pipeline is mathematically accurate.

Index currency metadata for search

Use LlamaIndex to build a searchable database of global currencies. By calling `get_supported_codes` and indexing the results, your RAG pipeline can instantly map country names to official codes. You can also feed detailed metadata from `get_enriched_data` into your vector index. This lets users query complex currency traits using natural language, with the agent pulling the answers straight from your index.

Synthesize historical trends

Combine historical rate documents with live API data. Your LlamaIndex pipeline can fetch past rates using `get_historical_data` and index them alongside your internal financial reports. When a user asks about portfolio performance, the agent queries both your vector store and the live API. It uses `get_latest_rates` to calculate current valuations against those historical benchmarks.

Setup guide

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