Currents MCP vs Playwright E2E MCP
A side-by-side look at the Currents MCP and Playwright E2E MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Currents MCP for browser automation work as a local process; choose Playwright E2E MCP for browser automation as a local process. You can also run both side by side in one mcpServers block.

run-testRun the project's Playwright tests: stats plus each failure's file:line, kind and message. Diagnoses missing installs, dead dev servers, syntax errors, crashes and timeouts (kills the tree, keeps partial results). Reports progress; background: true returns a run id for long suites. Runs are recorded for analyze-history.get-run-statusProgress (tests done/total, failures so far) or the final result of a run-test background run; the result becomes the last run for get-failure. waitSeconds waits; cancel stops it. Default: the latest run.get-failureAnalyze one failure from the most recent run-test execution: full message and code frame, expected vs actual, stack trace, failed network requests (4xx/5xx and dead endpoints), console errors, failure kind (assertion/timeout/browser-crash/syntax/config/server-unreachable) and concrete next steps. Use run-test first.suggest-fixPatch a failure from the last run: a drifted locator is matched against the DOM at failure (trace, or live url) and replaced with one proven unique; changed copy gets the new expected text. Returns a diff and confidence; apply: true writes it, re-runs the test and reverts if still red. Refuses when the element is truly missing (app bug).inspect-pageOpen a URL headlessly and return its elements with Playwright locators proven unique on the page (role + name first), CSS selectors, visibility, text and console messages. storageState/headers open it signed in; actions click/fill first to reach a state. view 'locators' is the compact map.list-testsList the Playwright tests available in the project (file, line, full title, projects), with optional filtering. Uses `playwright test --list` when Playwright works and falls back to a source scan when the install or config is broken, reporting why.validate-selectorCheck a CSS selector, Playwright selector or locator (getByRole/getByTestId…, .first(), .filter()) on a live page: validity, match count (actions need exactly 1), sample matches and a sturdier verified locator for each. Accepts storageState/headers/actions.audit-accessibilityRun axe-core on a live page (WCAG 2.2 AA by default) and return violations worst first, each with the offending elements as verified Playwright locators, the fix, and a regression check to paste into a spec. Accepts storageState/headers/actions to audit pages behind a login or after a step.generate-e2e-testScaffold a Playwright test from a description using the project's REAL selectors. Scans the agent's recent file changes (git working tree / last commit, mtime fallback), extracts data-testid / role / label / placeholder / id locators with their source locations, optionally cross-checks them against the live page, writes a ready-to-run spec, and returns next steps.compare-visual-stateVisual regression check: screenshot a live page (or element), compare it to a stored baseline, and report how many pixels changed, WHERE they changed (bounding regions), and the average color shift ("blue → red"). First call saves the baseline; later calls compare. Writes a red-highlighted diff image for review.diagnose-flakyRepeat failing tests with retries disabled and return a per-test, evidence-based verdict: CONSISTENTLY FAILING (real bug), FLAKY (pass/fail counts, error-signature variance, duration spread) or NOT REPRODUCING. Runs all repetitions in one process by default. `isolate: true` also re-runs the failures with one worker to tell parallelism bugs (shared state) from flakiness inside the test; `order: true` (Playwright 1.64+) runs the files in random orders to catch tests that depend on what ran before them. Defaults to the tests that failed in the most recent run.analyze-historyAnalyze the local run history (.playwright-e2e-mcp/history.jsonl, written by every run): 'flaky' ranks tests that flip pass/fail and lists broken or regressed ones; 'patterns' groups failures by cause; 'test' shows one test's timeline.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Currents MCP is bring-your-own-key: usage is billed by the API provider you supply a key for. Auth: api key required. Playwright E2E MCP is listed as free. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add currents-dev-currents-mcp and playwright-e2e-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
