What is the Applitools MCP Server?
Connect your Applitools Eyes testing suite to your AI agent and manage your entire visual regression pipeline without opening the dashboard. Allow your agent to spot UI changes, validate baselines, and assess testing health dynamically.
What you can do
- Batch Observability — Query active test batches to view aggregated statuses (Passed, Failed, Unresolved) and completion rates
- Session & Results analysis — Drill down into specific test sessions to examine failed step images, match levels, and browser differences
- Baseline Management — List your "golden" graphical baselines bound to applications or specific Git branches
- Actionable Maintenance — Authorize the agent to delete outdated baselines or discard legacy batches to keep your workspace clean
- Key Validation — Ensure connectivity against your visual AI engine before pipeline triggers
How it works
- Subscribe to this server
- Insert your Applitools API Key
- Review visual bugs and validate frontend changes directly from Claude, Cursor, or any MCP-compatible surface
Who is this for?
- QA Automation Engineers — ask your agent to summarize unresolved test batches and pinpoint exact OS/browser failure combinations
- Frontend Developers — verify branch-specific visual baselines during PRs without context switching
- Engineering Managers — pull high-level batch stats to ensure release criteria are visually met
- Designers — request a quick breakdown of structural UI changes caught by Applitools Visual AI before deployment
Built-in capabilities (10)
Use when a baseline is outdated or a page has been redesigned. Delete an Applitools test baseline

Frequently asked questions
Can my AI agent resolve a test failure on its own?
No. The MCP server is designed for pulling state data—it retrieves batches, session diff links, and match levels so you can review them locally. Approving a new baseline or resolving a mismatch still requires human intervention within the Applitools Eyes dashboard to maintain absolute testing safety.
Can I use the agent to delete old UI snapshots?
Yes. If your UI has undergone major structural changes and old baselines are causing false positives, you can authorize the agent to execute the delete_baseline tool. Provide the exact baseline ID to instantly discard the legacy screenshot from your workspace.
How fast can I summarize test errors after my CI/CD action triggers?
Almost instantly. Rather than scrolling through dozens of Applitools logs, ask your agent to 'Get batch stats for ID 123'. It will immediately return the aggregation of Passed, Failed, and Unresolved runs, saving you countless minutes of digging.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
