How to Use the Azure Functions Invoke MCP in LlamaIndex

Q: How does Azure Functions Invoke integrate with LlamaIndex indexes?

Use the McpToolSpec to wrap the server, then add the invokefunction tool to your agent list. Once executed, you can index the returned output into your vector store.

Q: Can I filter which Azure Functions Invoke tools LlamaIndex sees?

You can use the allowedtools filter during setup. This restricts your agent to specific functions, keeping your index clean and focused.

Turn cloud function results into searchable knowledge for LlamaIndex. Stop ignoring API data and start indexing it.

Index cloud data with LlamaIndex

Run `invoke_function` and feed the output directly into your vector store. Your index now contains fresh data from your cloud backend, not just static documents. This creates a living knowledge base. When your agent queries the index, it retrieves real-time results from your functions.

Ground your agent in real data

Use the `invoke_function` tool to gather facts before your agent answers a user. It stops the guessing game by forcing the agent to fetch current data first. This makes your RAG pipeline accurate. The agent works with verified JSON output from your own servers.

Automate document creation from APIs

Call `invoke_function` to get the latest business records and add them to your index. LlamaIndex then treats this data like any other document. It bridges the gap between your serverless compute and your RAG application. You define the flow, and the agent keeps the index updated.

Setup guide

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

Common questions about Azure Functions Invoke MCP in LlamaIndex

Use the McpToolSpec to wrap the server, then add the `invoke_function` tool to your agent list. Once executed, you can index the returned output into your vector store.

Yes, use the async tool list method provided by the MCP spec. This prevents your RAG pipeline from blocking while waiting for a cloud response.

You can use the allowed_tools filter during setup. This restricts your agent to specific functions, keeping your index clean and focused.

Only if you explicitly add it to your vector store. The server itself is ephemeral and doesn't store your query history.

We use zero-trust transport for every call. Your function results are transmitted directly to your agent's memory and are never cached on our servers.
