How to Use the Bandwidth Alternative MCP in LlamaIndex

Q: How do I make Bandwidth Alternative tools available to a LlamaIndex agent?

First, instantiate the BasicMCPClient with your server URL. Then wrap it with McpToolSpec and call totoollistasync() to get a list of tools for your agent.

Q: Can I filter which Bandwidth Alternative tools my LlamaIndex agent can use?

Yes. The McpToolSpec constructor accepts an allowedtools argument. You can pass it a list of tool names, like 'sendsms', 'listmessages', to restrict the agent's capabilities.

Q: What's the main benefit of using Bandwidth Alternative with LlamaIndex?

Indexing. The output from tools like listcalls isn't just a one-time result; it becomes part of a searchable knowledge base. This lets you ask complex questions about your past communications activity.

Turn your Bandwidth Alternative account into a searchable knowledge base with LlamaIndex. Query your call history and configs in plain English.

Index Your Call and Message Logs

This MCP server lets LlamaIndex query your comms activity. Your agent can use `list_calls` and `list_messages` to pull recent history. LlamaIndex then automatically indexes this data into a vector store of your choice. Now you can ask natural language questions like, "How many calls did we make to area code 212 last week?" and get answers grounded in actual call data from your Bandwidth Alternative account, not hallucinations.

Live Data from this MCP Server for LlamaIndex

Your agent isn't limited to static documents or old data. It can use `get_account_info` or `get_call_state` to fetch live information directly from your Bandwidth Alternative account during a query. This fresh data augments the context for the LLM. It means answers about your account's current state are much more accurate because they're based on what's happening right now.

Query Your Account Configuration

Stop clicking through dashboards to find what you're looking for. A LlamaIndex agent can run `list_phone_numbers` and `list_applications`, then index the output. This creates a searchable snapshot of your Bandwidth Alternative setup. From there, you can ask your agent things like, "Which phone numbers are assigned to the support application?" or "What's the ID for the primary app?" and get an instant, accurate answer pulled from your indexed data.

Setup guide

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