How to Use the Texter MCP in LlamaIndex

Q: How do I use LlamaIndex to search Texter messages?

You index the results from listtextermessages. When you query, LlamaIndex performs a semantic search against that indexed message content, giving you contextually relevant answers.

Q: Can LlamaIndex track changes to Texter labels?

Yes. If you run addlabeltotexterchat and index the results, your knowledge base updates. You can then query how a specific label was assigned or when it changed.

Q: Does LlamaIndex support querying Texter chat details?

It does. By indexing the output of gettexterchatdetails, you create a searchable record. You don't need to manually pass the ID; LlamaIndex helps you find the right data point.

Q: What kind of data can be indexed from Texter with LlamaIndex?

You index everything: message content, chat labels, department names, and even the full list of connected channels. It's all written into your vector store.

Q: If I use Texter messages in a query with LlamaIndex, what data type is available?

The primary data types you index are message content, along with chat labels and department IDs. This makes the context highly specific to your communications.

Perplexity

Search past chat transcripts and history.

LlamaIndex indexes the output of `list_texter_messages`. This means you can't just view the messages; you query them. You ask a question about old conversations, and LlamaIndex grounds the answer in the actual `message content` from your chat history.

Retrieve current departmental data for context.

The output of `list_texter_departments` gets indexed. This allows your RAG application to answer questions like, 'Which departments handle billing?' using live API data instead of relying on general knowledge or hallucinations.

Build a searchable record of chat metadata.

When you run `get_texter_chat_details`, LlamaIndex takes that detailed JSON output and makes it part of your unified index. You can then query the full details—including labels and status—without knowing the exact `chatId` upfront.

Setup guide

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