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 server provides 10 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Sending messages the old way requires endless tab-switching and CSV uploads.
Today, running a targeted campaign means exporting your contact list, cleaning it up in a spreadsheet to remove bad numbers, segmenting it into groups, and then manually uploading or pasting that data into a separate messaging dashboard. If you change one phone number, you repeat the whole cycle—it's slow, error-prone, and impossible to audit fully.
With Sinch MCP Server, your agent handles this entire process in natural conversation. You tell it which group needs messages; it runs `list_sms_groups` internally, confirms the list size, executes the send via `send_sms`, and then gives you a single report from `get_delivery_report`. It's done entirely within your chat window.
Sinch MCP Server: Send messages & manage contacts
Manual batch management involves tracking which list version was used for which message send, and then cross-referencing those IDs with separate delivery reports. If you can't find the original batch ID, figuring out what failed is a massive headache.
This server makes it simple. You manage all batches using `list_sms_batches` and get full details via `get_batch_details`. Your agent tracks everything, linking the initial send to the final delivery report status in one place. It's clean, auditable, and fast.
What you can do with this MCP connector
You're connecting your AI agent to Sinch, a heavy-duty platform built for handling SMS at scale. This setup gives you full control over every part of an SMS campaign—from building contact lists to managing what happens after you hit send. You don't just send texts; you manage the whole damn process.
Sending Texts (Send Text Messages)
To blast out a message, you use the send_sms tool. It handles sending text messages (SMS) to one or multiple people using international formatting. Whether you need to hit up single contacts or send out a burst of texts, this tool gets it done.
Managing Contacts (Manage Contact Groups)
You gotta organize your numbers first. You can use create_sms_group to build and save brand new groups of phone numbers specifically for campaigns. If you need the rundown on an existing group, run get_group_details; that'll tell you exactly how many members are in it. And if a campaign is done or the list got trashed, you can permanently wipe out an old contact group using delete_sms_group.
To see what groups you’ve already set up, just call list_sms_groups.
Tracking Deliveries (Track Delivery Status)
When it comes to knowing if your message actually landed, the get_delivery_report tool is key. It pulls the full delivery report for a batch, letting you see the total number of people targeted, how many delivered, which ones are still pending, and exactly where the failures happened. You won't be guessing about your reach with this.
Controlling Message Batches (Control Message Batches)
The list_sms_batches tool generates an inventory of all recent SMS batches that have been created or processed. If you need deep facts on a specific batch, use get_batch_details; it'll show you the status and parameters used for that run. You can also modify what’s in an already-existing campaign using update_sms_batch.
And if something goes sideways before delivery, you can stop the whole thing dead with cancel_sms_batch. Keep in mind, though: this action is irreversible.
Getting Your Overview (List Contacts)
To keep everything straight, you've got two listing tools. You can call list_sms_groups to get an inventory of every contact group defined. For a history check on campaigns, run list_sms_batches to see all recently processed batches.

How Sinch MCP Works
- 1 First, provide the Sinch API credentials (Service Plan ID and API Token) to your AI client.
- 2 Next, instruct your agent on the workflow—for example, 'List all contact groups,' or 'Send a reminder SMS to group X.'
- 3 The agent uses the exposed tools (
list_sms_groups,send_sms, etc.) to execute the commands and returns structured data about the results (e.g., delivery status, batch ID).
The bottom line is you get a full command-line interface for SMS marketing, letting your AI client manage campaigns without touching a dashboard.
Who Is Sinch MCP For?
Marketing managers who need to run targeted outreach but hate the manual work of copy/pasting lists. Customer support agents who have to send bulk updates and track failures quickly. Ops engineers building automated communication pipelines that can't rely on human intervention.
Runs segmented SMS campaigns for promotions, ensuring the right message hits the correct contact group.
Sends transactional updates (like 'Your ticket is resolved') to multiple users and immediately checks the get_delivery_report to verify delivery success.
Integrates SMS messaging into a larger workflow, automating the creation of groups and the sending of batches via API calls.
What Changes When You Connect
- Audit failed deliveries instantly. Instead of waiting for manual reports, use
get_delivery_reportto get precise metrics on delivered vs. failed messages after any campaign run. - Manage recipients like a pro. Use
create_sms_groupandlist_sms_groupsto keep your contact lists clean and segmented before running campaigns, ensuring you only target active numbers. - Control the message lifecycle. If a batch needs adjusting or cancellation, use
get_batch_detailsandupdate_sms_batchto intervene mid-process without manual API calls. - Process high volumes reliably. The
send_smstool handles multiple international phone numbers in one go, making bulk outreach simple for your agent. - Simplify list maintenance. Instead of manually checking which groups exist, run
list_sms_groupsto get a complete inventory and plan your next campaign.
Real-World Use Cases
Handling an emergency product recall message.
The marketing lead needs to notify 50 key clients immediately. They ask their agent: 'First, list all contact groups.' The agent uses list_sms_groups to find the VIP group ID. Then, it calls send_sms with the critical alert message and gets immediate confirmation of the batch initiation.
Verifying a large mailing's success rate.
An operations team sends 20,000 messages. Hours later, they need to know how many failed due to bad numbers. They prompt their agent: 'Get the delivery report for batch 123.' The agent uses get_delivery_report and provides a breakdown of failures vs. successes instantly.
Adjusting an ongoing marketing campaign.
A campaign targeting new users needs a slight change in message content mid-day. Instead of restarting, the manager tells their agent: 'Update batch 456 with this new text.' The agent uses update_sms_batch to modify parameters on the existing batch without downtime.
Cleaning up obsolete contact lists.
The company acquired a client list but some groups are outdated. A developer instructs their AI agent: 'Review all current groups and delete group 7.' The agent runs list_sms_groups first, verifies the name, then uses delete_sms_group, making cleanup traceable.
The Tradeoffs
Sending messages to a group that might be deleted.
The developer just assumes 'Group A' still exists and calls send_sms for it. The message fails silently or the call returns an error code, leaving the user unsure if they need to fix the list first.
→
Always confirm group existence first. Run list_sms_groups to get a current inventory, verify the exact name, and then use that confirmed name in your campaign workflow.
Trying to update a batch without knowing its ID.
The user tries to call update_sms_batch but only remembers 'the morning batch.' The API rejects the request because it requires a specific, unique batch identifier, causing workflow failure.
→
First, use list_sms_batches to get a list of recent batches and find the correct ID. Then pass that exact ID when calling update_sms_batch.
Relying only on success confirmation during sending.
The agent successfully executes send_sms, reports 'queued for delivery,' and the user assumes 100% success. However, spam filters or carrier blocks may cause later failures that are never reported back.
→
After any major send operation, immediately follow up by calling get_delivery_report to get hard data on final status (delivered/failed), not just queue status.
When It Fits, When It Doesn't
Use Sinch if your primary need is auditable, scalable communication via SMS. You need granular control over message batches and recipient lists. This tool shines when you have a multi-stage workflow: 1) Validate recipients (list_sms_groups); 2) Prepare the campaign (create_sms_group or update_sms_batch); 3) Execute the send (send_sms); 4) Check results (get_delivery_report).
Don't use this if you just need to send a single, one-off message. For that, direct API calls are simpler than involving group management. Also, don't rely on it for email campaigns; Sinch is strictly for SMS.
If your goal is purely list generation, start by using list_sms_groups to map out what you have before attempting any send operation.
Common Questions About Sinch MCP
How do I check if a group exists using Sinch MCP Server? +
You run list_sms_groups to view all existing groups. If the group you need isn't listed, you must use create_sms_group first.
Can I cancel a message send using Sinch MCP Server? +
Yes, if the batch hasn't left the system yet, you can call cancel_sms_batch. This is useful for catching mistakes before they cost money or frustrate customers.
What tool do I use to send messages with Sinch MCP Server? +
You use the send_sms tool. Remember to provide phone numbers in international format (e.g., +1234567890) for it to work.
What is the difference between `get_batch_details` and `get_delivery_report` using Sinch MCP Server? +
get_batch_details gives you metadata about the batch itself (like its parameters or status). get_delivery_report provides the outcome—the actual delivery counts, failures, and success percentage.
What credentials do I need to successfully use the `send_sms` tool? +
You must provide your Sinch Service Plan ID and API Token. The server uses these keys for authentication, so you'll set them up once in your AI client connection. You won't have to worry about manual auth steps again.
When using the `send_sms` tool, what phone number formatting is required? +
Numbers must be in international format (e.g., +1234567890). You can send texts to multiple recipients; just list all the numbers you want in the 'to' field. The API handles sending them out.
How do I change parameters for a batch using `update_sms_batch`? +
The tool lets you adjust settings on an existing, pending SMS batch. You must provide the Batch ID and define exactly what parameters need updating. This is useful if campaign details change before they are sent out.
What specific data points does `list_sms_batches` provide? +
This tool returns a list of recent SMS batches, including the Batch ID, when it was created, and its current status. Your agent uses this data to select which batch needs further monitoring or action.
Can it accidentally affect my entire Sinch account? +
No. The integration only supports sending SMS, managing batches, and handling contact groups. It cannot modify billing, account settings, or access other Sinch services.
How does authentication work? +
You provide your Service Plan ID and API Token. The integration generates a Bearer token header automatically for each request — no OAuth setup required.
What is a batch in Sinch? +
A batch is a single SMS send operation that can target one or many recipients. Each batch has a unique ID and can be tracked, updated, or cancelled before delivery.
