What is the Percy MCP Server?
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
- Enable the structural node mapping target locally inside your logic constraints securely
- Incorporate explicitly bounds adding your single Percy Project Token statically internally gracefully
- 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
Built-in capabilities (10)
/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 a single Percy snapshot. Marks it as visually correct, updating the baseline for future comparisons
Get full details of a Percy build including state, total/unreviewed snapshot counts, approved/rejected snapshots, branch, commit SHA, and finalized timestamp
Get full details of a Percy project including name, slug, default branch, auto-approve enabled, browser targets, and build count
Get full details of a Percy snapshot including name, review state, widths, fingerprint, and comparison count
List all supported browser families on Percy. Returns browser names, versions, and OS combinations for cross-browser visual testing
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 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 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 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

Frequently asked questions
Can the AI automatically approve an entire Percy build limit safely via constraints natively?
Absolutely strictly explicitly natively. The integration encapsulates the approve_build action dynamically structurally executing the final endpoint verification marking bounds explicitly matching visual approvals effortlessly saving limits.
How explicitly strict are the parameter bounds when extracting image comparisons logistically?
Invoking Explicit bounding via list_comparisons tracks native image differences safely cleanly bounding metrics returning explicit difference percentages mapping base width loops directly over testing node grids explicitly gracefully natively.
Where structurally globally do I find my Explicit Percy integration token accurately gracefully?
Navigate explicit bounds inside your native Percy workspace parameters explicitly mapping 'Project Settings > Integrations/Tokens'. Globally limit testing node arrays explicitly generating Token strings seamlessly securely correctly internally securely elegantly here.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
