Perplexity

Automated Multi-Step Communications via MCP Server

The agent uses `get_balance` first. This checks the current account balance, allowing subsequent steps to determine if a message can actually be sent. After confirming funds, the agent can call `list_phone_numbers` and then execute `send_sms`. It builds an entire workflow: check money, find number, send text.

Managing Accounts with LangChain

`list_applications` lets your AI client see every application linked to the Vonage Alternative account. This gives full visibility into setup. You can also list all active users using `list_users`. The agent knows who has access and what permissions they operate under.

Analyzing Call History with LangChain

`list_voice_calls` pulls a record of recent voice calls. This lets the agent analyze call patterns, duration, and outcomes. Pairing this with `list_conversations` gives a full picture. You don't just see that a call happened; you know what was discussed in those conversations.

Setup guide

Set up Vonage Alternative MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Vonage Alternative tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "vonage-alternative-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
