How to Use the Arize AI MCP in Cursor

Q: How do I configure Arize AI in my Cursor editor?

You add the MCP Server to your .cursor/mcp.json file in your project root or global settings. Once configured, enable Agent mode in the Cursor chat panel to start calling the tools.

Q: Can Cursor use Arize AI spans to write unit tests?

Yes, Cursor uses the listspans tool to pull real production inputs and outputs. The agent then writes local unit tests based on those exact payloads to prevent future regressions.

Q: How do I compare Arize AI experiments in the Cursor chat?

You ask the agent to run the listexperiments tool to fetch recent evaluation runs. Cursor compares these runs side-by-side in your editor sidebar so you can see which code changes performed best.

Q: Can I list my active machine learning projects directly in the editor?

Yes, the listprojects tool fetches your entire project catalog. This lets you quickly switch context between different models and datasets you are working on.

Generate production fixes in Cursor using real-time Arize AI spans and model performance metrics directly in your editor.

Debug failing code using live Arize AI spans in Cursor

The `list_spans` tool pulls live execution traces from your production models straight into your Cursor composer. You don't have to copy-paste trace IDs from a web console when a pipeline breaks. Cursor reads the exact execution path and matches it against your local files. The agent writes the fix for the buggy function using the real inputs and outputs that triggered the production alert.

Inject model configurations into code generation

The `get_model` tool retrieves the exact schema and performance details of your active deployments, while `list_projects` locates the target environment. This ensures your editor knows the exact shape of the data your code is dealing with. When you ask Cursor to write a new prediction parser, it uses these real schemas instead of guessing. You get working code that matches your production environment on the first try.

Build regression tests from production data

This MCP Server uses `create_dataset` and `list_datasets` to turn production failures into local test suites. You can also run `list_experiments` to verify how your local changes compare to previous evaluations. Your agent pulls the failing payloads, formats them into a local test file, and saves the new dataset back to Arize. You close the loop between monitoring and testing without leaving your editor.

Setup guide

Set up Arize AI MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Arize AI MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Arize AI transactions." If the MCP tools are loaded correctly, Cursor will call the Arize AI tools automatically. You can also check Settings → MCP for a green status indicator.
