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.
Dealing with messy dashboards and manual list management is exhausting.
Right now, updating your subscriber base means logging into the dashboard. You have to click through multiple menus just to check if a user has the correct custom tags or to see which lists they belong to. Then you might have to download a CSV, open it in Excel, make changes, and re-upload everything.
With this MCP, your AI agent handles all that complexity for you. You simply tell your agent what you want—'Find me everyone who hasn't opened an email in 90 days.' It runs the query, gives you the result, and lets you act on it right away.
The EasySendy MCP makes list management conversational.
You don't need to remember which button does what. You can ask your agent to find all your lists with `list_all_lists`, then tell it to delete the ones that are empty, or use `create_list` when a new campaign starts.
It means you stop thinking in terms of buttons and fields, and start thinking about the goal: a perfect list. That's how good your campaigns become.
What your AI can actually do with this
Stop building complicated spreadsheets just to update a few names or check who hasn't opened an email in months. This MCP connects your AI agent directly into the backend of EasySendy, letting you manage your entire subscriber lifecycle through natural conversation. You can ask your agent to find all users tagged as 'High Value' and then tell it to add them to a new campaign list—all without logging into a dashboard.
When Vinkius hosts this MCP, your AI acts like an expert marketing operations specialist that never sleeps.
It’s about getting granular control: you can check custom fields, manage opt-in types, or even delete entire lists if they're obsolete. It treats your mailing list like a living database, letting you keep your audience clean and ready for the next big send.

Here's how it actually works
The bottom line is you get full control over your mailing lists by simply talking to your AI client.
First, subscribe to this MCP and grab your Public API Key from your EasySendy dashboard.
Next, paste that key into your AI client's settings. Your agent now has direct access to the list management tools.
Then, start talking to it. Just ask things like, 'Get me all my active lists,' or 'Add this group of 50 people.' It handles the rest.
Who is this actually for?
This MCP is for marketing operations teams and growth managers who spend too much time clicking through dashboards or wrestling with CSV imports. If your job involves keeping email lists clean, segmented, and ready for high-volume sends, you need this.
They use it to automate lead ingestion from multiple sources and ensure custom tags are correctly applied across all subscriber records.
They rely on it to quickly check list details, find specific segments, and add users into campaigns without manual data exports.
They use it to manage the subscriber lifecycle, handling unsubscriptions or updating contact fields before a major campaign launch.
What Changes When You Connect
Instead of logging into the dashboard to find out what lists you have, just ask the agent to list_all_lists. It instantly shows every group you manage. This saves time and eliminates clicking through menus.
Need to onboard a big client list? Use add_multiple_subscribers to dump hundreds of contacts at once. Forget manual CSV uploads; it handles the scale in one command.
Running into compliance issues? You can use unsubscribe_user or update_list to manage opt-in status instantly. This keeps your list clean and protects your sender score.
Want context on a user's history? Run get_subscriber_details on any email address to see their full profile, tags, and join date before you write the next campaign.
When you need structured data, get_list_fields pulls all custom tags for a list. This lets your agent build hyper-specific segments, making campaigns much more targeted.
See it in action
Cleaning up old lists
A manager notices that the '2021 Leads' list is full of inactive people. Instead of manually checking each profile, they ask their agent to run get_subscriber_details for a sample and then use delete_subscriber on all stale records. The list becomes healthy overnight.
Onboarding a new partner segment
The sales team gets 500 new contacts from a conference. Instead of exporting them to Excel, the marketer uses add_multiple_subscribers and tags them immediately with 'Conference Q2' so they can target them later.
Correcting profile errors
A key client changed their job title. The marketing ops engineer runs update_subscriber via the agent to fix the record instantly across all lists, ensuring communications are accurate.
The honest tradeoffs
Assuming data is clean
Running a campaign without checking user status because you just assume everyone on the list is active.
Always start by running get_list_fields and then use get_subscriber_details to verify critical fields before sending anything out. Don't guess.
Updating records in bulk via CSV
Exporting 10,000 names to Excel, making minor changes, and then trying to re-import them into the dashboard.
Use add_multiple_subscribers for large additions. If you need to update records, use update_subscriber through your agent; it's cleaner.
Trying to manage list structure manually
Manually renaming a list and then forgetting to update all the campaign templates that reference its old name.
Use update_list first, and always confirm the changes. If you need to wipe it clean, use delete_list—but only when absolutely sure.
When It Fits, When It Doesn't
Use this MCP if your core job is keeping email contact data accurate and ready for high-volume sends. You should use it anytime you need to check user details (get_subscriber_details), manage list membership (adding, deleting, or unsubscribing), or audit tags (get_list_fields). Don't use this MCP if your primary goal is just sending the email; that's handled by other tools. If you only need a simple contact database without mailing capabilities, look for a dedicated CRM tool instead of trying to manage everything here.
Questions you might have
How do I see what lists are available with EasySendy MCP using `list_all_lists`? +
Running list_all_lists instantly gives you every list ID and name in your account. You'll know exactly which group to target for the next campaign.
What is the difference between `add_subscriber` and `add_multiple_subscribers`? +
add_subscriber handles one person at a time, useful if you're correcting a single record. Use add_multiple_subscribers when you have an array of many contacts to add fast.
Can I check what custom fields are available for a list using `get_list_fields`? +
Yes, running get_list_fields pulls all the specific tags and metadata attached to that particular list. This is key for segmentation.
What should I do if a user has changed their email address? Do I use `update_subscriber`? +
You can use update_subscriber. It lets you modify specific details for an existing user, like changing their profile information or status.
If I want to remove a user, do I use `delete_subscriber` or `unsubscribe_user`? +
unsubscribe_user formally removes them from receiving emails. delete_subscriber is stronger; it actually deletes the record completely from your database.
What information do I need to provide when using the `create_list` tool? +
You must specify a unique name for the list. This function lets you structure your audience data before importing users or running campaigns. It's best practice to add descriptive tags during creation so you can easily segment it later.
When using `add_multiple_subscribers`, how does the system handle errors or skipped records in a large batch? +
The tool processes subscribers individually and returns a detailed report. You get clear status codes for every entry, showing exactly which users were added successfully and why any others failed.
If I need to change the name or description of an existing group, how does `update_list` work? +
The update_list tool allows you to modify the list's metadata without affecting its subscribers. You simply provide the List UID and the new details; it handles the rest.
How do I find my EasySendy API Key? +
Log in to your EasySendy account, click on your profile (top right), select APIs, and copy your Public API Key.
Can I search for a subscriber by email? +
Yes! Use the get_subscriber_details tool and provide the List UID and the subscriber's email address to retrieve their full profile.
How do I import multiple subscribers at once? +
Use the add_multiple_subscribers tool and provide a JSON array containing the subscriber details (EMAIL, FNAME, LNAME, etc.).
