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 8 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Manually managing content feeds is a constant pain point.
Today, maintaining an email marketing presence means switching between the list manager dashboard, downloading contacts into Excel, and then copying specific feed IDs into the analytics portal. You spend time cross-referencing names, checking subscription statuses, and confirming that a new article has been properly syndicated to all necessary lists—it’s slow, error-prone copy-paste work.
With this MCP, your agent handles the entire process. Instead of clicking through multiple tabs or exporting CSV files, you simply tell your AI client what needs to happen: 'Update list X with contacts from Y.' You get instant, verifiable changes across every feed and mailing list associated with your account.
FeedBlitz MCP gives you granular control over subscriber data.
Before this, removing a user required finding their email address in the right interface, clicking the un-subscribe button, and hoping nothing else broke. Getting basic metrics meant pulling reports that sometimes lagged or didn't show the specific list you cared about.
Now, your agent can run `list_metrics` on syndication ID 123, confirm user details with `get_subscriber`, and clean up lists using `remove_subscriber`—all in one conversational flow. The data is immediately accurate, reliable, and actionable.
What your AI can actually do with this
Need to run a campaign but hate jumping between spreadsheets, list managers, and analytics dashboards? This MCP handles the whole workflow. It connects your AI agent directly to FeedBlitz’s back end, giving you control over every aspect of your outbound communications. You can dynamically manage subscriber lists, check user profiles for details, and even pull performance metrics for specific feeds—all without writing boilerplate code.
When you connect this through Vinkius, it becomes one more powerful action available in your agent's toolkit. It takes the manual effort out of growing an audience; instead of managing contacts list by painful list, you just ask your AI client to handle the communication pipeline.

Here's how it actually works
The bottom line is you pass the secure API key to your agent; it handles all the necessary communication with FeedBlitz for you.
Subscribe to the FeedBlitz MCP and configure your necessary lists within the platform.
Obtain your API Key from the developer settings panel.
Provide that key to your AI agent, granting it permission to execute list management tasks.
Who is this actually for?
Content managers, growth hackers, and marketing operations staff who waste hours manually updating contact lists. If your job involves sending mass emails or maintaining content feeds, this is for you.
Runs batch updates on mailing lists, ensuring new contacts are added and inactive users are removed automatically.
Monitors the engagement metrics for different content feeds (syndications) to figure out which articles need promotion.
Tests new user acquisition funnels by programmatically adding and removing subscribers across multiple test lists.
What Changes When You Connect
Stop manual data entry. Use add_subscriber to add new contacts instantly, letting your agent handle the plumbing instead of you.
Track performance without clicking tabs. Run list_metrics to get immediate insights into open rates or active subscribers for any list.
Maintain clean lists easily. If someone moves on, use remove_subscriber to immediately unsubscribe them across all feeds.
Check user status fast. Need to know if a client exists? Use get_user to retrieve their full account details in seconds.
Map your entire setup at a glance. Run list_syndications when you need an overview of every list and feed you manage.
See it in action
Auditing a mailing list for compliance
The team needs to know exactly who is currently subscribed before running a major campaign. Instead of downloading a CSV and manually checking statuses, the agent runs list_subscribers on the target syndication ID. This gives them an immediate, filtered report they can review.
Onboarding new content streams
A new product line requires three dedicated mailing lists and a corresponding RSS feed. The agent first uses list_syndications to check existing feeds, then uses the necessary tools to create and populate the required new lists automatically.
Diagnosing poor campaign performance
The newsletter open rate dipped last month. Instead of guessing, the agent executes list_metrics on the main feed ID. The resulting data shows a specific drop in activity correlated with the date it was sent.
Data cleanup after an acquisition
The company acquired three smaller blogs, each with its own subscriber list. Instead of manual merging, the agent uses list_syndications to identify all new lists and then cross-references them using get_user before consolidating.
The honest tradeoffs
Asking for 'everything' in one go
The user asks the agent, 'Show me everything about my subscribers and feeds.' This results in a confusing wall of data that mixes list names with individual metrics.
Break it down. First, use list_syndications to get all feed IDs. Then, loop through those IDs calling list_metrics for each one. This structured approach provides actionable reports.
Assuming a user exists
The agent tries to run a campaign update using an email address that was never properly added or verified in the system.
Always check first. Use get_subscriber with the specific email to confirm existence before attempting any write operation like adding them via add_subscriber.
Missing list context
The user asks to run metrics without specifying which mailing list ID they mean. The agent fails because it doesn't know the scope.
Always start by calling list_syndications so you have the exact ID needed for tools like get_syndication or list_metrics.
When It Fits, When It Doesn't
Use this MCP if your workflow centers on managing communications: lists, feeds, and engagement metrics. You need to know who is subscribed and how they are engaging with the content. Don't use it if you just need simple CRUD (Create, Read, Update, Delete) operations on a single database table; an internal data service MCP will handle that better. If your goal is purely user authentication or payment processing, look for a dedicated identity management tool instead.
Questions you might have
How do I see all the mailing lists available? (list_syndications) +
You run list_syndications. This tool returns an overview of every active list and feed you manage, giving you a master inventory to work from.
Can I add a new user to a list using the add_subscriber tool? +
Yes. To add someone, use add_subscriber and provide the target syndication ID along with the email address you want to add.
What is the difference between get_user and get_subscriber? +
get_user pulls general account details for a publisher. get_subscriber focuses specifically on one person's status within your mailing lists.
How do I check engagement metrics using list_metrics? +
Specify the syndication ID you want to check and call list_metrics. The agent will return key performance data, like open rates and active counts.
What parameters does the `remove_subscriber` tool require to ensure a successful unsubscription? +
It requires the syndication ID and the subscriber's email address. This method handles both active removal and simple unsubscription requests, making it easy to clean up lists when necessary.
If I need more than just the name, how can I get all details for one list using `get_syndication`? +
Using get_syndication, you retrieve a complete profile of a specific feed. This goes beyond simple names and gives you structural details about the syndication itself.
Can I use `list_subscribers` to filter for inactive or pending users? +
Yes, you can filter results using status parameters within the list_subscribers tool. This lets your agent pull only certain groups of users from a large list.
What happens if I use `get_subscriber` but don't have an exact subscriber ID? +
You can typically pass the email address to the get_subscriber tool. It finds and verifies details for that specific user, even if you don't have their internal account identifier.
Can the AI Agent send bulk email campaigns directly? +
No, the agent currently focuses on managing lists, syndications, and subscribers. Campaigns are typically dispatched automatically via RSS by FeedBlitz.
Does the FeedBlitz MCP support filtering subscribers by status? +
Yes, you can instruct the AI to filter subscribers by providing a specific status like active or unsubscribed when querying a syndication.
Are metrics retrieved in real-time? +
Metrics reflect the latest data available in FeedBlitz's systems, providing near real-time insights into your syndication's performance.
