MCP tools — 16 exposed · ~3,483 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

e2e_analyze ~324

Analyze a page's structure and return all interactive elements (forms, buttons, links, navigation, tables, modals, etc.) with their CSS selectors, plus suggested test scaffolds. One call replaces the entire screenshot→guess-selectors→retry cycle.

Input Output Examples

Name	Type	Req	Description
authStorageKey	string	—	localStorage key name for the auth token (default: "accessToken")
authToken	string	—	JWT or auth token to inject into localStorage before navigating (for authenticated pages)
cwd	string	—	Absolute path to the project root directory. Claude Code should pass its current working directory.
delay	number	—	Wait N milliseconds after page load before analyzing (default: 0)
includeScreenshot	boolean	—	Include a screenshot alongside the JSON analysis (default: true)
maxElements	number	—	Max elements per category (default: 50). Lower values produce smaller responses.
scope	string	—	CSS selector to limit analysis to a section (e.g. "#sidebar", ".modal-content")
selector	string	—	Wait for this CSS selector before analyzing
url	string	yes	Full URL to analyze (e.g. "https://example.com" or "http://host.docker.internal:3000/dashboard")
waitUntil	string	—	Navigation wait strategy. "auto" (default) tries networkidle2 first with a short timeout, then falls back to domcontentloaded + delay for SPA/WebSocket apps. Use "domcontentloaded" for apps with pers…

e2e_capture ~276

Capture a screenshot of any URL on demand. Connects to the Chrome pool, navigates to the URL, takes a screenshot, and returns the image with its ss:HASH.

Input Output Examples

Name	Type	Req	Description
authStorageKey	string	—	localStorage key name for the auth token (default: "accessToken")
authToken	string	—	JWT or auth token to inject into localStorage before navigating (for authenticated pages)
cwd	string	—	Absolute path to the project root directory. Claude Code should pass its current working directory.

No examples provided.

e2e_create_module ~217

Create a reusable module for E2E tests. Modules encapsulate repeated action sequences referenced via { "$use": "module-name", "params": {...} }. Good module candidates: auth setup, page navigation, tab clicking, opening sidebars/drawers, form fill sequences, cleanup routines. Modules can compose — a module can $use other modules. Params use {{paramName}} mustache syntax in action fields. Extract a module when you see the same 2+ action sequence in multiple tests.

Input Output Examples

Name	Type	Req	Description
actions	array	yes	Sequential actions with {{param}} placeholders for substitution
cwd	string	—	Absolute path to the project root directory.
description	string	—	Human-readable description of what this module does
name	string	yes	Module name (used in $use references, e.g. "auth-jwt", "navigate-patient")
params	object	—	Parameter definitions. Each key is a param name, value is { required: boolean, default?: string, description?: string }

No output schema declared.

No examples provided.

e2e_create_test ~1,266

Create a new E2E test JSON file. IMPORTANT: prefer built-in actions over evaluate blocks. ## Action selection guide (use instead of evaluate) **Clicking elements by text** — DON'T write evaluate to find+click elements: click: { type: "click", text: "Submit" } — searches button, a, [role=tab], span, etc. click_regex: { type: "click_regex", text: "save|guardar" } — regex match, case-insensitive click_menu_item: { type: "click_menu_item", text: "Delete" } — [role=menuitem], .MenuItem, etc. click_option: { type: "click_option", text: "Option A" } — [role=option] in dropdowns click_chip: { type: "click_chip", text: "Active" } — MUI Chip / tag elements click_icon: { type: "click_icon", value: "edit" } — SVG/icon by data-testid, aria-label, class click_in_context:{ type: "click_in_context", text: "Row text", selector: "button" } — child within container **Asserting text presence/absence** — DON'T write evaluate with body.includes(): assert_text: { type: "assert_text", text: "Welcome" } — text IS on page (case-sensitive). Uses: text assert_no_text: { type: "assert_no_text", text: "Error" } — text is NOT on page. Uses: text assert_text_in: { type: "assert_text_in", selector: "[class*='Drawer']", text: "profesional|doctor" } — scoped regex in container (case-insensitive default). Uses: selector + text (+ value:"exact") **Asserting elements** — DON'T write evaluate to count or check visibility: assert_visible: { type: "assert_visible", selector: ".modal" } — Uses: selector (NOT text) assert_not_visible: { type: "assert_not_visible", selector: ".loader" } — Uses: selector (NOT text) assert_count: { type: "assert_count", selector: "input", value: ">= 2" } — Uses: selector + value assert_element_text: { type: "assert_element_text", selector: "h1", text: "Dashboard" } — Uses: selector + text assert_matches: { type: "…

Input Output Examples

Name	Type	Req	Description
cwd	string	—	Absolute path to the project root directory. Claude Code should pass its current working directory.
hooks	object	—	Optional hooks: beforeAll, afterAll, beforeEach, afterEach (each an array of actions). Note: beforeAll runs on a SEPARATE page that is closed before tests — use beforeEach for auth/setup.
