Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 11 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
The overhead of managing multi-channel communications today is huge.
Right now, if you need a simple campaign update, you're forced into logging into the messaging portal. Then you have to check your credit usage in one tab, verify the sender name in another, and then manually copy phone numbers from a contact list into the message body box. It’s tedious, slow, and prone to human error.
With this MCP, that entire process vanishes. You just tell your agent: 'Send an alert about X.' The system handles checking `get_balance`, ensuring the sender is approved via `list_senders`, compiling the list using `create_list`, and finally sending the message with one clean action.
AvoSMS MCP: Reliable, Structured Messaging
The manual steps that go away include checking account health manually (`get_account_check`), refreshing list statuses to find out if contacts were added (`add_contact`), and then initiating the actual send. All of this is automated.
It's not just a message tool; it’s an operations control layer for your mobile outreach. You get consistent, scalable messaging delivery every single time.
What your AI can actually do with this
Getting bulk messages out used to feel like juggling five different dashboards. Now, your agent handles the whole flow. Instead of manually logging in, fetching contacts, checking credit balances, and hitting 'send,' you just ask your AI client to handle it. Your agent acts as a real-time operations manager for your business, sending notifications, scheduling future broadcasts, and managing approved sender identities on your behalf.
If you're tracking customer responses or monitoring account health, the process is invisible—you just get the result. Connecting AvoSMS via Vinkius lets your AI client access this deep suite of messaging tools alongside everything else in the catalog.

Here's how it actually works
The bottom line is, you talk to your agent like a normal person, and it handles all the API calls in the background.
Subscribe to this MCP, then provide your AvoSMS Account ID and API Key.
Your AI client accesses the tools. You ask it to perform a messaging operation (e.g., 'Send an SMS to X').
The agent executes the command through the appropriate tool and returns the result or confirmation.
Who is this actually for?
This is for anyone whose job requires high-volume, reliable mobile communication. Think marketing managers running campaigns or customer support teams that need instant alerts on incoming replies.
Automating campaign delivery by creating contact lists and sending messages to opt-in groups.
Reading incoming SMS responses directly from the chat interface or sending instant status alerts to customers.
Monitoring credit consumption and verifying delivery health across global networks to prevent service interruptions.
What Changes When You Connect
You can keep track of your budget by calling get_balance before running any bulk campaign, ensuring you don't run out of credits mid-send. It’s just good ops practice.
Instead of remembering list IDs or manually managing names, you tell the agent to use a specific Sender ID (via list_senders) and it handles the rest. Your brand always shows up right.
Need to update contacts? Just ask the agent to add_contact with a new number; no need to jump into a separate management UI just for one entry.
The best part is two-way comms. By calling list_responses, your agent reads incoming replies, keeping you looped in without manual polling or dashboard refreshers.
If a list gets corrupted or abandoned, you can use delete_list and delete_sender to clean up the backend records cleanly.
See it in action
Post-purchase follow-up
A marketing manager needs to send a 'Your order is ready' alert. They ask their agent, and it executes send_sms using a predefined sender name. The system automatically ensures the message goes out with the correct brand identity.
Handling customer inquiries
A support team member receives an SMS reply from a client. They ask their agent to list responses, and it calls list_responses. This keeps the conversation history visible directly in the chat interface for immediate action.
Auditing outreach compliance
An ops lead needs to know if they have enough funds before a major campaign. They ask their agent, and it runs get_balance first. This prevents them from wasting time on failed campaigns due to insufficient credits.
Building a new campaign target list
A manager needs to compile a group of VIP contacts. They ask the agent to add_contact several numbers and then use create_list to save that group, making it available for future bulk sends.
The honest tradeoffs
Trying to manage lists manually
Opening the AvoSMS dashboard, finding the list ID, and then copying phone numbers into a spreadsheet to verify who was contacted.
Just tell your agent to list_lists first. Then, ask it to execute add_contact or use create_list. The conversation handles the state management.
Forgetting account health checks
Running a huge bulk send on Friday afternoon only to find out that the API connection failed because no one checked the account status beforehand.
Always start by calling get_account_check and checking your funds with get_balance. It takes two seconds.
Using a generic sender name
Sending messages that appear to come from 'Unknown Number' because they didn't register an official Sender ID first.
Before sending, run create_sender and then use the resulting approved name when you call send_sms. It makes you look professional.
When It Fits, When It Doesn't
Use this MCP if your core requirement is high-volume, reliable communication via SMS. Specifically, if you need to manage sender identities, schedule outreach, or process two-way messaging threads—this is it.
Don't use it if you just need to send basic emails (use an email service provider instead). Also, don't use it for complex transactional data processing that requires structured schema validation; those scenarios are better handled by a Pydantic AI-type tool. If your process involves multiple stages of decision-making based on content (e.g., analyzing text replies), you might need to combine this with an agent orchestration suite, like CrewAI, after using list_responses to gather the data first.
Questions you might have
How do I check if my SMS credits are running low using the AvoSMS MCP? +
You run get_balance. This tool immediately tells you your remaining credit count, letting you plan your outreach budget without guesswork.
Can I list all approved sender names with the AvoSMS MCP? +
Yes. Use list_senders to pull a complete manifest of every Sender ID that is ready for use in your outgoing messages.
What should I do if my contact list needs updating on the AvoSMS MCP? +
First, you can run list_lists to see what groups exist. Then, you simply call add_contact with the new numbers and the agent updates the group.
How do I send an SMS message using the AvoSMS MCP? +
You use the send_sms tool by providing the recipient's number, your chosen sender ID, and the message content in one prompt.
How do I check incoming customer replies using the AvoSMS MCP? +
Run list_responses to pull all recent messages sent directly to your business number. This ensures your agent can maintain a complete, two-way conversation history with your audience.
How do I verify my AvoSMS account connection using the AvoSMS MCP? +
Start by calling get_account_check. This function instantly verifies that your API keys and credentials are active, preventing you from sending messages before confirming your setup.
How do I manage multiple contact groups using the AvoSMS MCP? +
You can begin by running create_list to segment contacts. Later, use list_responses and add_contact in conjunction with list_lists to keep track of all your defined groupings.
How do I request or remove a custom sender identity using the AvoSMS MCP? +
Use create_sender when you need to formally request and approve a new Sender ID name. If an identity is no longer needed, you can clean it up with delete_sender.
What is a sender ID and why do I need one? +
A sender ID is the alphanumeric label (3-11 characters) that appears as the sender on the recipient's phone. Approved sender IDs help increase trust and open rates for your messages.
Can I receive replies to my SMS messages? +
Yes! Use the list_responses tool to retrieve any incoming messages from your customers. This allows your agent to handle two-way communication workflows.
How do I ensure my SMS is delivered at a specific time? +
When using the send_sms tool, provide a YYYY-MM-DD HH:MM:SS string in the date parameter. AvoSMS will queue the message and deliver it exactly at the requested time.
