Capacidades integradas (10)
approve_build
/approve` moving the test suite to green. Approve all unreviewed snapshots in a Percy build. Marks the entire build as visually approved for deployment
approve_snapshot
Approve a single Percy snapshot. Marks it as visually correct, updating the baseline for future comparisons
get_build_details
Get full details of a Percy build including state, total/unreviewed snapshot counts, approved/rejected snapshots, branch, commit SHA, and finalized timestamp
get_project_details
Get full details of a Percy project including name, slug, default branch, auto-approve enabled, browser targets, and build count
get_snapshot_details
Get full details of a Percy snapshot including name, review state, widths, fingerprint, and comparison count
list_browsers
List all supported browser families on Percy. Returns browser names, versions, and OS combinations for cross-browser visual testing
list_builds
List builds for a Percy project. Each build contains snapshots from a test run. Returns build IDs, states (processing/finished/failed), branch names, commit SHAs, and snapshot counts
list_comparisons
List visual comparisons for a Percy snapshot. Each comparison shows the diff between baseline and head at a specific width/browser. Returns diff images, diff percentages, and browser info
list_projects
List all projects on Percy (BrowserStack). Percy is the leading visual regression testing platform that captures snapshots and detects pixel-level UI differences across builds. Uses JSON:API format. Returns project names, slugs, and browser configs
list_snapshots
List snapshots in a Percy build. Each snapshot is a captured page/component at specific widths and browsers. Returns snapshot names, review states (unreviewed/approved/rejected), and diff percentages
Lo que este conector desbloquea
Inject precision quality assurance workflows directly bounding LLM models via the Percy Visual Testing API (by BrowserStack). Programmatically verify pixel regressions executing queries evaluating visual boundaries natively across target projects. Inspect deep status arrays parsing CI build limits dynamically, extract metrics evaluating granular snapshot checkpoints asynchronously, and force immediate test baseline approvals seamlessly directly from explicit prompt commands naturally.
What you can do
- Project Navigation — Read bounded parameters tracking Percy deployments isolating configurations determining explicitly specific active QA targets natively
- Automated Build Oversight — Track specific arrays extracting dynamic checks returning pipeline checkpoints (approved/failed/unreviewed limits) explicitly seamlessly
- Visual Snapshot Operations — Log natively extracting bounds verifying comparison properties logging rendering differences mapping exact explicit width constraints
- Baseline Affirmations — Mutate bounding loops forcing active execution of JSON logic structurally bypassing native clicks allowing test approvals implicitly (
approve_buildorapprove_snapshot)
How it works
1. Enable the structural node mapping target locally inside your logic constraints securely
2. Incorporate explicitly bounds adding your single Percy Project Token statically internally gracefully
3. Engage conversational agents dynamically explicitly retrieving UI test results bounding seamlessly
Who is this for?
- QA & Testing Engineers — extract specific arrays parsing failed assertions tracking structural rendering regressions safely returning granular boundaries immediately iteratively
- Frontend Teams — resolve visual bounds logging pipeline limits running explicitly without traversing complex dashboards isolating errors easily intelligently natively
- DevOps Admins — verify explicit pipeline health tracking CI loop states explicitly monitoring unreviewed elements globally reliably securely
