Attribution Model Comparator MCP for AI. Know exactly how much credit every marketing channel deserves.
Works with every AI agent you already use
…and any MCP-compatible client








Connect to your AI in seconds.
Attribution Model Comparator instantly compares five major attribution models—First Touch, Last Touch, Linear, Time Decay, etc.—to pinpoint exactly where revenue credit went wrong across your marketing channels.
Instead of guessing which touchpoint deserves the sale credit, this MCP quantifies the actual difference in revenue contribution (the delta) for every channel from a single conversion event.

The hardest part of marketing analytics is building the report itself.
Right. So, today you pull data from your CRM dashboard—that's one tab. Then you jump to Google Analytics for web interactions; that’s a second export. You copy-paste those two datasets into a spreadsheet and manually try to map the customer ID across both systems just to figure out what happened before they bought.
With this MCP, your agent handles all of that messy data stitching automatically. It establishes the full touchpoint sequence first. Then it calculates shares using specific models, giving you an immediate answer on how much credit every single channel deserves.
Attribution Model Comparator: Get Actionable Revenue Deltas
You stop having to run five different reports and then compare them in a meeting. You just ask for the comparison, feeding the data into `calculate_attribution_delta`. It instantly highlights where your models disagree on revenue credit.
This means you walk away from meetings with definitive numbers—you know exactly which model is giving you an inflated or deflated view of your performance. Period.
What your AI can actually do with this
When someone buys something, figuring out who gets credit is messy. Was it the initial ad seen on social media? Or maybe the final email reminder that got them to click 'buy'? Traditional reporting fails because they treat these complex paths like simple straight lines. You end up with siloed views of customer value.
This MCP solves that by building a full picture first. It maps out every touchpoint a customer interacted with leading up to a sale. Then, it runs the total revenue through five different accounting methods—First Touch, Last Touch, Linear, and others—and compares them head-to-head. You don't just get shares; you get the difference between those shares, telling you precisely which model over- or under-credits specific channels.
It’s a powerful layer of analysis that helps you understand true performance, all managed within Vinkius.
019ec1f0-2424-7308-b9c0-5d54e5c016dc Here's how it actually works
The bottom line is that this MCP turns a messy web of marketing interactions into clear, comparative financial reports.
First, establish the data foundation by using get_customer_journey to pull all touchpoints linked to a specific customer ID.
Next, use fetch_conversion_metrics to get the total sale value for that conversion event. Then, run calculate_attribution_shares multiple times—once for each model you want to compare.
Finally, feed all the generated share data into calculate_attribution_delta. This tool delivers a direct comparison showing exactly how much revenue credit differs between your selected models.
Who is this actually for?
Marketing Operations Managers and Data Analysts who are tired of building complex attribution spreadsheets manually. This tool stops you from having to stitch together data from multiple systems just to answer one question: 'Where did the real money come from?'
Uses this MCP to compare First Touch and Last Touch models, figuring out which channels need better budget allocation.
Runs the full suite of tools to reconcile multiple sales records and identify revenue discrepancies across five different accounting methodologies.
Requires a single source of truth for customer value, using this MCP to present accurate, defensible reports to leadership.
What Changes When You Connect
Pinpoint true revenue gaps. Use calculate_attribution_delta to immediately see the financial difference between, say, Linear and Time Decay models for a specific channel.
Build complete customer profiles instantly. Run get_customer_journey first; this gives you all the ordered touchpoints needed before any calculation can run.
Get accurate value totals. fetch_conversion_metrics pulls the final sale amount, ensuring your attribution shares are based on correct revenue figures.
Compare multiple models at once. You don't have to run reports five different ways; you use calculate_attribution_shares across all models for a holistic view.
Eliminate manual spreadsheet work. By chaining these tools together, your agent handles the complex data flow from journey map to revenue delta automatically.
See it in action
Diagnosing Underperforming Channels
A marketing manager noticed their social ads seemed important but couldn't prove it. They asked their agent to first use get_customer_journey and then run calculate_attribution_delta. The result showed that 'Social Ads' receive significantly less credit under the Last Touch model than they should, proving a gap in reporting.
Validating Budget Shifts
The leadership team is considering cutting email marketing spend. A data analyst used fetch_conversion_metrics and then ran calculate_attribution_shares for both the Email Newsletter model and a competitor's paid search model to quantify exactly how much revenue credit each channel currently receives.
Understanding Complex Sales Paths
A customer journey involved reading documentation, watching a webinar, and finally buying. The user ran get_customer_journey followed by multiple calls to calculate_attribution_shares, giving them the proportional contribution of each touchpoint (documentation vs. webinar) for that specific conversion.
Finding Model Flaws
A team wants to prove whether a 'Position-Based' model is better than 'First Touch'. They used fetch_conversion_metrics and then passed the data into calculate_attribution_delta, which instantly flagged that the two models assigned wildly different amounts of revenue credit for their target channel.
The honest tradeoffs
Manual Spreadsheet Comparison
Pulling raw data from your CRM, exporting it to Excel, and manually creating five separate pivot tables—one for each attribution model—to compare shares.
Instead of manual work, let your agent chain the tools. Start with get_customer_journey, then use calculate_attribution_shares multiple times, and finish by feeding everything into calculate_attribution_delta. It takes seconds, not hours.
Focusing Only on First Touch
Only analyzing the initial touchpoint, which ignores all subsequent interactions (like support articles or remarketing ads) that actually closed the sale.
You need a full picture. Run get_customer_journey to map the entire path first. Then use various models via calculate_attribution_shares to ensure you're accounting for every touchpoint's true value.
Ignoring Conversion Value
Running attribution calculations using only the number of transactions without factoring in the total dollar amount, leading to skewed insights.
Always start by calling fetch_conversion_metrics. This ensures every share calculation uses the accurate, reconciled revenue value for that conversion event.
When It Fits, When It Doesn't
Use this MCP if your core problem is quantifying causality across a complex path. You need to know which marketing touchpoints deserve credit when multiple interactions lead to one sale. This is mandatory when comparing different financial models (First Touch vs. Linear, etc.). Don't use it if you just need simple ROI tracking for one-off campaigns; those are easier to track manually. And don't use it if your data isn't tied back to a single conversion ID—you need the foundation of fetch_conversion_metrics first. If your goal is simply reporting basic channel volume, this MCP gives you too much detail and might be overkill.
Questions you might have
What is the necessary input data to start an attribution comparison? +
You must first use the get_customer_journey tool, providing a customer ID and conversion date. This establishes the ordered sequence of touchpoints needed for all subsequent calculations.
How do I get the financial value used as a baseline for attribution? +
Use fetch_conversion_metrics with the specific conversion ID. This tool retrieves the total revenue amount, which serves as the single, absolute figure that all five attribution models will proportionally divide.
After calculating shares for multiple models, how do I find out which model is most biased? +
The calculate_attribution_delta tool takes the full results from all share calculations (via calculate_attribution_shares) and compares them. It quantifies the revenue gain or loss for a specific channel across models, highlighting discrepancies.
If I run `fetch_conversion_metrics` with a conversion ID that doesn't exist, what happens? +
The system returns an error code immediately. Your agent will flag the invalid ID and stop the process, allowing you to correct the identifier before proceeding.
When I use `calculate_attribution_shares`, do I need to run `get_customer_journey` first? +
Yes. The tool needs the chronological sequence of touchpoints provided by get_customer_journey to accurately calculate proportional revenue share credit.
Can I batch process multiple conversions when using `calculate_attribution_shares`? +
While designed for single inputs, your agent can loop through a list of conversion IDs. This allows you to run the shares calculation across many customers in one automated sequence.
What should I consider regarding rate limits when using `calculate_attribution_delta`? +
Vinkius manages throttling for stability. If you are comparing hundreds of channels, break the request into smaller batches by time period or channel group to avoid hitting performance caps.
When calling `calculate_attribution_shares`, how do I ensure the touchpoints used are correct? +
You must provide a list of specific channels and models. The tool uses this explicit input to calculate shares, so don't rely on default channel inclusion.
