How to Use the Front MCP in LlamaIndex

Q: How do I index Front email threads using LlamaIndex?

You pull the Front message history using listconversationmessages and load the text nodes into a LlamaIndex Document object. From there, you index the email content into a VectorStoreIndex to enable semantic search over past customer conversations.

Q: Can I limit which Front tools are visible to LlamaIndex?

Yes, you can use the allowedtools filter when initializing the LlamaIndex client. This lets you expose read-only tools like listallconversations while blocking write tools like sendinboxreply for safer automated MCP workflows.

Q: Can I connect multiple Front shared inboxes to one LlamaIndex?

Yes, you run listsharedinboxes to identify all target Front inbox IDs. Your LlamaIndex ingestion pipeline then loops through each ID to build a unified index of your entire team's communications via this MCP Server.

Index Front shared inboxes into vector stores to ground LlamaIndex RAG applications in real conversation data.

Index Front threads for semantic search in LlamaIndex

LlamaIndex calls `list_conversation_messages` and `get_conversation_details` to turn your Front email history into a searchable knowledge base instead of just running basic keyword searches. The framework extracts real support resolutions and indexes them directly into your vector database. When a new customer email arrives, your RAG pipeline queries this index to find how similar issues were resolved in the past. This lets your LlamaIndex agent draft highly accurate replies using `send_inbox_reply` based on historical team decisions.

Ground Front MCP Server tool calls in live LlamaIndex queries

Your LlamaIndex agent checks live Front data using `search_conversations` before drafting any response to prevent hallucinations from ruining customer relationships. The framework combines the live API payload from `get_inbox_details` with your static product documentation. This ensures that when the LlamaIndex agent calls `send_inbox_reply`, the email content matches both current engineering specs and your live inbox status. You don't have to worry about your agent making up answers to technical customer questions.

Map Front shared inbox structures to LlamaIndex query engines

By exposing tools like `list_shared_inboxes` and `list_inbox_threads` as LlamaIndex tool specs, you turn your Front setup into a structured query engine. The framework maps these tools to data schemas that your query engine can parse. This allows users to ask natural language questions about Front inbox volume or assignee workloads. The LlamaIndex query engine automatically resolves these questions by executing the correct sequence of MCP tools behind the scenes.

Setup guide

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