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_build or approve_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_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

FAQ

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 Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
