# What's new in June 2026

Published Jun 30, 2026

## The Checkly MCP Server is here

The first version of the Checkly MCP Server is live. Point your AI client at the server URL and manage your monitoring from any MCP-capable agent — setup instructions per client are in the docs.

```

```

## Download check artifacts straight from the terminal

No more digging through nested check-result JSON. `checkly assets list` and `checkly assets download` pull the artifacts of any check run or test session — logs, Playwright traces, videos, screenshots, reports — into your local folder.

## Tag Manager: manage tags in one place

Rename tags everywhere they are used, delete unused or misspelled ones, and add tag descriptions that give Rocky AI extra context for root cause analyses. Available in the UI under Configuration.

[Open Tag Manager →](https://app.checklyhq.com/accounts/tag-manager)

## The Checkly Slack app

Install the Checkly Slack app to receive alerts and rerun checks or AI analyses directly from Slack. It replaces webhook-based Slack alerts and comes with a new CLI construct.

## Also shipped

- **Large CLI deploys:** projects with thousands of resources now deploy reliably, with progress output and `--cancel-in-progress-deployment` to take over a running deploy.
- **Test sessions:** [drill into a single result with `checkly test-sessions get --result `.](https://www.checklyhq.com/docs/cli/checkly-test-sessions/)
- **CLI:** [delete a check by ID with `checkly checks delete`, and manage account members with `checkly account members update / delete`.](https://www.checklyhq.com/docs/cli/checkly-checks/#checkly-checks-delete)
- **Agentic Checks:** cancel test prompt runs, test session runs, and check runs from the API and UI.
- **API:** check result responses now include the OpenTelemetry trace ID, so you can correlate a run with its trace.
- **DNS monitors:** [now support the HTTPS resource record type.](https://www.checklyhq.com/docs/detect/uptime-monitoring/dns-monitors/configuration/#https-record-rfc-9460)
