Send Personalized SMS Messages from a Spreadsheet Using Claude Cowork and Vonage

Michael Crump — Tue, 14 Jul 2026 19:25:48 +0000

AI assistants are no longer just answering questions - they're taking action. Claude Cowork is a great example of this shift: it can access your local environment, read and write files, and automate tasks that would otherwise eat up your time. Pair it with the Vonage Tooling MCP Server, and you can send real SMS messages to real people, all from a plain-English prompt.

In this tutorial, we'll walk through exactly how to do that. We'll use Claude Cowork to read customer feedback from a local spreadsheet, generate personalized responses using AI, and automatically send each one as an SMS via Vonage.

🎬 Watch the full video walkthrough here: Send a Text in Claude Cowork

What You'll Build

Imagine you run a restaurant. After each visit, customers text you their feedback, and you save their name, phone number, feedback, and a status column (Pending / Sent) in a spreadsheet called restaurant_feedback.xlsx.

Using Claude Cowork, you'll create a task that:

Reads the spreadsheet and finds all rows with a Pending status
Uses AI to determine the sentiment of each message and generate a personalized response
Sends each response as an SMS using the Vonage Tooling MCP Server
Updates the status column to Sent

Prerequisites

Before you get started, make sure you have:

Claude Desktop (latest version)
Node.js installed
A Vonage Developer account (free to sign up)

Step 1: Install the Vonage Tooling MCP Server

Open Claude Desktop, click the Claude menu in your computer's menu bar, then go to Settings → Developer → Edit Config.

This opens (or creates) a file called claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Paste in the following configuration:

{
  "mcpServers": {
    "vonage-mcp-server-api-bindings": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@vonage/vonage-mcp-server-api-bindings"
      ],
      "env": {
        "VONAGE_APPLICATION_ID": "<YOUR_VONAGE_APPLICATION_ID>",
        "VONAGE_PRIVATE_KEY64": "<YOUR_VONAGE_PRIVATE_KEY64>",
        "VONAGE_API_KEY": "<YOUR_VONAGE_API_KEY>",
        "VONAGE_API_SECRET": "<YOUR_VONAGE_API_SECRET>",
        "VONAGE_VIRTUAL_NUMBER": "<YOUR_VONAGE_VIRTUAL_NUMBER>",
        "VONAGE_WHATSAPP_NUMBER": "<YOUR_VONAGE_WHATSAPP_NUMBER>",
        "RCS_SENDER_ID": "<YOUR_RCS_SENDER_ID>"
      }
    }
  }
}

Step 2: Get Your Vonage Credentials

API Key & Secret
From your homepage, click API Secret Management to copy your API key and secret.

Application ID & Private Key

Go to Build → Applications → Create a new application
Give it a name and click Generate public and private key - the private key will download automatically
Under Capabilities, toggle on Messages
Click Generate new application to get your Application ID

Before pasting the private key into the config file, you'll need to base64 encode it. Use the encoder linked in the Vonage MCP Server readme or run:

base64 -i private.key

Virtual Number
Go to Build → Phone Numbers to find or purchase a virtual number. Link it to your application, and if you're in the US, make sure it's 10DLC compliant.

Once your config is saved, restart Claude Desktop. To confirm the server is connected, open a new chat and ask:

"Do you have access to Vonage's tooling server?"

Claude should confirm and list its available capabilities.

Step 3: Set Up Your Spreadsheet

For this demo, create a file called restaurant_feedback.xlsx in a folder called operations. It should have columns for:

Name	Phone	Feedback	Response	Status
Jane	+1...	"Great food!"		Pending
Bob	+1...	"Service was slow."		Pending

The Status column is what Claude will use to know which messages need to be addressed.

Step 4: Create a `claude.md` Instructions File

To avoid re-prompting Claude every time, create a file called claude.md in your operations folder. This is a plain-text markdown file where you store persistent instructions for Claude Cowork.

Here's an example of what to put in it:

## Restaurant Feedback Automation

When prompted with `generate_responses`:
- Read `restaurant_feedback.xlsx`
- Find all rows where Status = "Pending"
- Analyze the sentiment of each feedback message
- If positive: set Response to "We're glad you had a positive experience!"
- If negative: set Response to "We're sorry you had a negative experience!"
- Save the responses back to the spreadsheet

When prompted with `send_responses`:
- Read `restaurant_feedback.xlsx`
- For each row where Status = "Pending" and a Response exists:
  - Send the Response as an SMS to the customer's Phone number using the Vonage Tooling MCP Server
  - Update the Status to "Sent"

💡 Tip: You can ask Claude itself to help you write your claude.md file!

Step 5: Run It in Claude Cowork

Switch to Cowork mode in Claude Desktop. Create a new task and click "Work in a project" in the bottom-left corner of the prompt box. Select your operations folder.

Now run:

generate_responses

Claude will scan the spreadsheet, find the Pending rows, analyze sentiment, and write personalized responses back to the file.

When you're ready to send, run:

send_responses

Claude will use the Vonage Tooling MCP Server to send each SMS and update the status to Sent. Open your spreadsheet to confirm - the status column should now show Sent for each row.

What's Next?

This is just the beginning of what you can do with the Vonage Tooling MCP Server. Beyond SMS, you can:

Send WhatsApp or RCS messages by populating the corresponding fields in your config
Trigger automated voice calls instead of (or in addition to) texts
Track delivery status by saving read/delivered receipts back to your spreadsheet
Build multi-channel workflows that escalate from SMS to voice if a message goes unread

The Vonage Dev Discussion: How AI is transforming software development

Liz Acosta — Thu, 21 May 2026 19:25:53 +0000

Welcome back to the Vonage Dev Discussion! Recently, members of the Vonage Developer Relations team met up in New York to create content, make plans, and hang out. We even got the chance to record at a super cool studio in the Big Apple!

We took the opportunity to chat about something that’s been on everybody’s mind: artificial intelligence. We talked about how AI is impacting developer relations and tech in general.

We have a second part coming out soon, but in the meantime, we want to know: What’s one thing that AI helps you with? Where do you still prefer to do the work yourself?

We’d love to hear your thoughts in the comments below 🤖👇

The Vonage Dev Discussion: Defining what an API is

Liz Acosta — Wed, 13 May 2026 20:49:48 +0000

This week we kicked off the first in a series of office hours. Our office hours are a judgment-free space for developers to come and ask questions about using Vonage – and get an answer live from an actual human!

Being able to ask questions without fear of judgment is so important for beginner engineers and being able to answer those questions is equally important for senior engineers. Have you ever noticed how explaining something makes you really think about what you actually know or don’t know? It's a really good feedback loop!

So here’s a chance to test your knowledge: How would you explain what an API is to someone? What are some examples of APIs you use?

And if you’re new to APIs, here’s a walkthrough of how to use one from our office hours:

And don’t worry! If you run into any issues, we can help you out in our next office hours. Check out the office hours schedule and make sure to subscribe to our YouTube channel for future streams and videos ♥️🤓

Let's keep the API conversation going in the comments below! 💻 👇

The Vonage Dev Discussion: Making mistakes

Liz Acosta — Fri, 24 Apr 2026 20:01:26 +0000

Nobody is perfect! Even the most seasoned developers have made mistakes – it’s all just part of the learning process.

One mistake that is so common in software development is accidentally pushing secrets to a public repository 🙈🙉🙊

Fortunately, there are lots of different guardrails you can put in place to help prevent the exposure of sensitive information like API keys, and we’ve covered a few of them in these posts about environment variables.

But we’re curious: What are some mistakes you’ve made as a developer? What did you learn from those mistakes?

Share your wisdom in the comments below! 🙏👇

The Vonage Dev Discussion: Builder pattern

Liz Acosta — Tue, 07 Apr 2026 16:48:06 +0000

Have you ever heard of the builder pattern? 🧰🏘️

In software development, the builder pattern is a creational design pattern that lets you construct complex objects step by step. It is especially helpful when you have complex classes of objects that can be extended in many different ways.

In this video, our developer advocates Guillaume Faas and Jeremy Foster discuss the builder pattern and how it is implemented in the Vonage .NET SDK.

The builder pattern sparks debate in the dev community. Some swear by it, others see it as over-engineering. We want to know: What's your take?

Do you use the builder pattern?

How do you use it in your own work?

How would you explain it to someone?

Share your experience and knowledge of the builder pattern in the comments below!

The Vonage Dev Discussion: Open source

Liz Acosta — Wed, 25 Mar 2026 16:59:12 +0000

At Women+ in Open Source Day, I got to try my hand at making a contribution to Apache Spark. While I didn’t manage to clone and build the project within the allotted time, I did get to speak with one of the project’s key contributors, Holden Karau, and was inspired by her encouragement for all sorts of people to get involved.

Contributing to open source can be intimidating! And in the age of AI, contributors from diverse perspectives are even more important.

So for our second ever Dev Discussion, we want to know: What is your advice for getting started contributing to open source projects?

Share your advice in the comments below along with links to some of your favorite open source projects! 🖥️ 🎉👇
