How to Use the BulkSMS MCP in LlamaIndex

Q: How do I limit access to BulkSMS tools?

Use the allowedtools filter when setting up your tool spec. This ensures your agent only interacts with the specific BulkSMS functions you permit.

Index BulkSMS data in LlamaIndex

Pipe the results of `list_messages` into your LlamaIndex vector store. This lets your RAG application query historical message content using natural language. Your index stays current by periodically pulling updates from the server. You no longer need to hunt through your dashboard to find what you sent last week.

Search contact groups

Use `list_groups` to pull your contact segments into your searchable knowledge base. Your agent can then answer questions about which specific groups received a particular campaign. This creates a bridge between your raw communication logs and your semantic search index. You find the right audience by asking your agent directly.

Ground responses in account data

Use `get_account_info` to provide context for your agent's answers. Your RAG app can reference your account ID and settings when generating reports on your messaging activity. By grounding the agent in live API data, you stop the guessing game. The agent reports only on what it sees in your account right now.

Setup guide

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