Debugging test failures used to mean clicking through five different tabs.
Today, when a regression occurs, your workflow breaks. You open the Mabl dashboard, find the specific run ID, click into it, and scroll through endless logs trying to determine if the failure was because of bad code or just a temporary UI glitch. Then you copy parts of that log into Slack, asking a teammate to interpret it.
With this MCP, you simply ask your agent: 'What went wrong with the last checkout run?' The system runs `mb.get_execution` and returns a full analysis package—a precise error reason, diagnostic text, and a screenshot showing exactly what failed. You get answers, not log snippets.
Get instant quality verification with Mabl MCP.
The manual steps that disappear are the need to switch between monitoring tools, manually listing environments, and trying to piece together a failure narrative from disparate sources. You don't have to remember which test plan is linked to which label or environment variable.
Now, you control the entire quality pipeline through natural language commands. It’s not just an API connection; it’s instant operational visibility.
What Mabl MCP does for your AI
This connector lets you treat your entire test suite like a conversation with your agent. Instead of navigating through complex UIs, you simply tell it what needs testing. You can list all available applications and then trigger specific test plans—say, the 'Checkout Regression' plan on the staging environment. Your agent monitors the run in real time, providing pass/fail rates and duration summaries as it progresses.
If something breaks, you don't just get a red status; you get detailed failure analysis. The system extracts precise error reasons, diagnostic insights, and even visual screenshots for rapid debugging. This capability is part of Vinkius’s massive catalog, giving your AI client deep control over your quality checks directly from your workspace.

Tell the agent which test plan to run, what environment to use, and wait for the failure analysis report.
Who uses Mabl MCP
QA Automation Engineers who are sick of copy-pasting test plan IDs and sifting through endless dashboards. Software Developers needing instant UI regression reports to verify builds before merging code. DevOps teams responsible for auditing CI/CD pipeline quality gates.
Uses the MCP to trigger complex test plans and analyze failure diagnostics conversationally, without leaving their IDE.
Verifies build quality by retrieving session screenshots and detailed outcomes for UI regressions directly from their workspace.
Audits CI/CD test results across multiple Mabl projects, monitoring environment health and associated variables efficiently.
Benefits of connecting Mabl MCP
Stop manually cross-referencing build logs and test dashboards. By using mb.get_execution, you get a single, comprehensive report that includes pass/fail rates, duration, and detailed failure analysis.
Never guess which environment to target again. Run mb.list_envs first, then tell your agent exactly where the plan needs to execute—staging or production—ensuring the right variables are loaded.
Reduce debugging time from hours to minutes. The MCP can extract precise root causes and visual screenshots for failed tests using the results of a run, bypassing vague error messages.
Manage complexity by organizing your suite. Use mb.list_labels to see all available tags and then trigger specific groups of tests using the mb.trigger_plan tool.
Keep track of what's running without switching tabs. You can use mb.list_executions for a quick status check, or mb.get_execution for a deep dive into any single test run history.
Mabl MCP use cases
Finding the source of an intermittent bug
A developer notices a UI regression but can't reproduce it locally. They ask their agent to find all applications using mb.list_apps, select the target app, and then trigger a run on the staging environment using mb.trigger_plan. The resulting failure analysis provides screenshots showing the exact visual overlay causing the button click failure.
Auditing a release candidate build
A DevOps engineer needs to confirm that all critical components passed testing before deployment. They ask their agent to list all test plans using mb.list_plans, select the 'Smoke Test' plan, and then use mb.get_execution on the last run ID to verify the overall pass rate.
Validating API changes in a new environment
A backend team updates an API endpoint and needs QA to validate it quickly. They first list all environments using mb.list_envs to confirm the correct staging URL, then use mb.trigger_plan on the dedicated 'API Health Check' plan.
Reviewing test coverage gaps
A QA engineer wants to know what tests are grouped together. They list all available labels using mb.list_labels and then use mb.get_app for the main checkout app to confirm which specific API endpoints were monitored.
Mabl MCP tradeoffs
What to watch out for, and the recommended way to handle each one.
Manually triggering tests in a GUI
Opening the Mabl dashboard, navigating to 'Test Plans', selecting the target environment from the dropdown, and hitting 'Run'. This process is slow and requires multiple clicks.
Instead of clicking through menus, simply tell your agent: 'Trigger the Checkout Regression plan on Staging.' The MCP handles the entire execution sequence using mb.trigger_plan.
Relying on vague error messages
The test fails and the log only says, 'Element not found.' This forces a manual investigation into console logs or network traffic.
Use mb.get_execution to pull up the detailed failure analysis. The MCP extracts diagnostic insights, often pinpointing why the element was missing (e.g., due to an unexpected visual overlay).
Forgetting which environment is active
A developer mistakenly runs a test intended for staging against production data because they didn't check the current context.
Always start by listing environments using mb.list_envs to verify the available contexts, then specify the exact target when you tell your agent to run the plan.
When to use Mabl MCP
Use this MCP if your primary pain point is orchestrating and analyzing complex, end-to-end user journey tests that touch multiple systems. If you need to trigger a full test suite (like 'Checkout Regression') across defined environments (staging/production) and then get a deep, actionable report on why it failed—this is for you. Don't use this if you only write simple unit tests or if your testing involves manual data entry that can't be scripted. For simple environment checks, you might just need mb.list_envs. But if the goal is to verify application quality and failure diagnostics conversationally, this MCP is what you need.

How do I list all my Mabl applications using the Mabl MCP? +
You use mb.list_apps. This tool gives you a complete catalog of every web, mobile, and API application that is currently monitored by your account.
Can I run a test plan on different environments using mb.trigger_plan? +
Yes, mb.trigger_plan allows you to execute specific plans across defined deployment stages like staging or production, ensuring the correct context for your tests.
What information does mb.get_execution provide about a failed test run? +
It gives full details of the execution, including the status, duration, pass/fail rates, and critical failure analysis reports with diagnostic insights and screenshots.
How do I check what environments are available for testing? +
You run mb.list_envs. This function returns all defined environment names, unique IDs, and any associated variables needed by the test plan.
Does the Mabl MCP help me find out which tests belong to a specific group? +
Yes, you can use mb.list_labels to view all organizational labels (tags). You can then reference these labels when triggering test plans to select grouped suites.
