How to Use the Saysimple MCP in LlamaIndex

Q: How do I connect the Saysimple MCP Server to LlamaIndex?

Install llama-index-tools-mcp and initialize the BasicMCPClient with your Vinkius URL. You then wrap it in McpToolSpec to expose tools like listchannels to your LlamaIndex agent.

Q: Can LlamaIndex query past customer conversations from Saysimple?

Yes, LlamaIndex uses listchats to fetch recent message threads and indexes them into your vector store. This allows your RAG application to answer questions based on real customer chat history.

Q: How does LlamaIndex handle outbound WhatsApp templates in Saysimple?

The framework uses listtemplates to search for matching templates, retrieves the specific structure via gettemplate, and sends the final payload using sendmessage. This prevents your agent from sending unapproved, freeform texts.

Q: Can I filter active messaging channels within LlamaIndex?

You can configure your LlamaIndex agent to call listchannels to identify which communication paths are active. This ensures the agent does not attempt to route an SMS template over a WhatsApp-only channel.

Q: Is my customer contact data safe when indexing Saysimple with LlamaIndex?

Yes, all data retrieved via listcontacts is processed locally within your LlamaIndex pipeline and never stored on Vinkius. The MCP connection uses single-token authentication to pull contact names and phone numbers securely without exposing your API keys.

Index your Saysimple customer chats and templates directly into LlamaIndex vector stores for highly accurate, context-aware RAG.

Index Saysimple messaging data for LlamaIndex RAG

This Saysimple MCP Server lets your LlamaIndex pipeline pull live conversations using `list_chats` and ingest them directly into your vector database for semantic search. You don't have to let your customer interaction history sit idle in closed inbox silos. By querying `get_chat` and `get_contact` dynamically, your agent builds a highly localized knowledge base of customer pain points. When a user asks a question, LlamaIndex searches past interactions to generate replies that match your actual support history.

Verify customer records before triggering LlamaIndex actions

Avoid sending duplicate messages by using Saysimple contact verification tools over an MCP connection within your LlamaIndex pipeline. LlamaIndex uses `list_contacts` to verify if a user exists, then retrieves their exact details using `get_contact` to ground the agent's reasoning. If the customer is new, LlamaIndex triggers `create_contact` to register them before attempting any outbound messaging. This strict validation step ensures your RAG pipeline only interacts with verified profiles in your database.

Retrieve approved WhatsApp templates for grounded generation

Keep your automated outreach compliant by querying Saysimple template tools directly from LlamaIndex. The framework queries `list_templates` to find pre-approved layouts, then uses `get_template` to extract the exact parameter structure required for the payload. Instead of generating freeform text that gets rejected, LlamaIndex fills the template variables with retrieved context and dispatches the message via `send_message`. This guarantees your automated notifications remain fully compliant and successfully delivered.

Setup guide

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