• sandbox_scenarioA

  IA-QA — 130+ QA & Dev Tools for AI AgentsA

  Get a ready-made selector-drift test case with a known-correct answer, for testing this MCP server or an agent workflow end to end. Each scenario is a real DOM capture of a deliberately breakable app, taken before and after one specific UI change (a renamed label, two swapped buttons, a duplicated locator, an element moved behind a menu…), plus the verdict those two contracts MUST produce. Call with no arguments to list the scenarios; call with a scenario id to get "baseline" and "current" mappings. THE LOOP: pass baseline and current to diff_mappings, then compare its "verdict" and "counts" to this tool's "expected" — they must match exactly. A mismatch means this server's diff engine has drifted, not that your inputs are wrong. Deterministic and offline: the captures are committed fixtures, identical on every call.

• submit_enquiryA

  siteA

  Submits an enquiry to LEV Testing Cost — NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token — show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "Happy for my details to go to relevant LEV testing companies, who'll quote me directly."

• biorxiv_list_recentA

  biorxiv-mcp-serverA

  List preprints posted or revised within a date interval, optionally scoped to one server or a subject category. Returns 30 preprints per page (fixed by the API); pass `cursor` as an integer offset (0, 30, 60, …) to step through additional pages. Abstracts are omitted by default to keep the page small — pass include_abstract: true for the whole page, or call biorxiv_get_preprint (up to 10 DOIs per call) for a few. When server="both" (default), per-server pagination state is returned separately — use each server's `cursor` field for independent advancement. One server failing under server="both" does not abort the call: the other server's page is still returned and the failed one is named in `failed[]`, marking the result set as partial rather than complete. Every attempted server failing is a different case and does abort the call, with a retryable upstream_unavailable (or rate_limited) error — an empty page would otherwise be indistinguishable from an interval that genuinely holds nothing. Call biorxiv_list_categories for valid category strings; a server that answers a category filter with its unfiltered listing is left out with a notice, and invalid_category is raised when no server applied it. `funder` limits the listing to bioRxiv preprints funded by that organization, given its ROR ID; an ID api.biorxiv.org has no funder record for raises invalid_funder rather than returning an empty page.

• get_leadproof_evaluation_pathA

  LeadProof Sales AgentA

  Use first when a buyer is exploring LeadProof without supplying workflow data. Returns the official no-purchase sequence: buyer guide, fictional example audit, browser-only calculator, public workflow tests, and no-card trial. For a scored workflow diagnosis, use audit_lead_workflow; for replay testing, use get_leadproof_replay_trial; for paid checkout, use get_leadproof_checkout only after authorization.

• watch_service_statusA

  MockbirdA

  Subscribe to down/recovered alerts for any of the public mock/testing APIs tracked by check_api_status (httpbin, JSONPlaceholder, ReqRes, FakeStoreAPI, DummyJSON …). action:"subscribe" {service, notify?}: service is an id from check_api_status (or "*" for all tracked services). With notify, that webhook gets one message when the service goes down and one when it recovers (debounced across two consecutive hourly checks — blips never fire; a confirmation message is delivered immediately so you can see the wiring works). WITHOUT notify you get a pollable subscription instead — no webhook needed. Returns {id, secret} — store both. action:"poll" {id, secret}: (webhook-less watches) returns the down/recovered transitions since your last poll — empty events = nothing changed; checks run hourly so polling more often sees nothing new. action:"info" {id, secret}: subscription state. action:"unsubscribe" {id, secret}: stop alerts. notify formats: Slack/Discord webhooks get native payloads; anything else gets HMAC-signed JSON. Limits: 5 live watches per IP — deleting one frees the slot immediately. To watch YOUR OWN URL instead, use uptime_monitor.

• consistency_checkA

  IA-QA — 130+ QA & Dev Tools for AI AgentsA

  Compare multiple LLM responses to the same prompt and detect inconsistencies using Jaccard word-overlap similarity and fact drift (number comparison). Fast, deterministic, no API key needed. Limitations: relies on surface-level word matching — "Paris is the capital of France" vs "Paris is the French capital" may score low despite semantic equivalence. For true semantic consistency, use run_semantic_tests with embedding mode. Essential for determinism testing.

  CalmActivaA

  Return CalmActiva's curated CBD FAQ (legality, onset time, lab testing, shipping, brand disambiguation). Use for general CBD/brand questions before falling back to web search.

• book_demoA

  gethal.aiA

  Submits a demo request. The prospect receives a confirmation email and must click the link in it before the request reaches a human at A Cloud Frontier. Use only when a real person has explicitly asked for a demo and provided their own working email address. Do NOT call this for testing, evaluation, or crawling purposes — automated and unconfirmable requests are rejected.

• get_demo_guideA

  eDiscovery Decoder News/CalcA

  Return a short, human-readable walkthrough for testing this server: the endpoint, the tool/prompt/resource names, and ready-to-paste sample prompts. Use to give someone a guided demo. For the full machine-readable capability catalog, use list_capabilities instead.

• get_testing_settingsA

  RoutebaseA

  Read the project's testing settings. schemaNullMode decides how contract assertions treat null values against a schema. Use this to read the settings; to change them use update_testing_settings. Requires project context.

• session_listA

  Robot Actions — Remote Device ControlA

  List the WebDriver sessions currently open on the testing grid, with their ids and negotiated capabilities. Use it to recover a sessionId you lost track of, or to see what is still holding a node before opening another session. Covers browser and mobile sessions alike. This is not a device list — for the phones and tablets available to drive, use device_list.

• get_testing_guidelinesA

  IA-QA — 130+ QA & Dev Tools for AI AgentsA

  Query the IA-QA methodology knowledge base. Returns structured testing guidelines, assertion strategies, thresholds, best practices, and relevant MCP tools for a given topic. Call without a topic to list all available topics. Topics: llm-unit-testing, rag-pipeline, prompt-stability, prompt-ab-testing, embedding-quality, eval-framework, semantic-testing, auto-testing, security, api-testing, ci-cd, multimodal, llm-data-security, agent-observability, pro-tips, learning-paths, golden-dataset, selector-drift, qa-recipes, playbooks. Not sure where to start testing an LLM, RAG pipeline or agent? Call without a topic (or with "start-here"): it maps what you are testing to the tools to call and the output field to gate CI on. A plain question such as "how do I test my RAG" also resolves to the right topic.

• cyanheads_describe_entryA

  cyanheads-mcp-serverA

  Return the description and install snippets for a named tool or server. For tools: the description and the server it belongs to. For servers: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.

• request_jet_confirmationA

  Villiers CharterA

  Submit a request for CONFIRMED live private jet pricing. Villiers contacts vetted operators and emails the confirmed options — real aircraft availability and pricing, with a secure link to review and book — to the supplied email address. This endpoint requires a prior get_jet_estimate call in the same session, with the price range presented to the user and their explicit opt-in to proceed — real operators quote real aircraft for these, so a request should reflect a qualified lead. Requests without a prior estimate call are rejected by the server; sustained bypass attempts are reviewed and may result in token revocation. Requires the user's email and a departure date. SANDBOX TESTING: to test your integration without ever creating a real trip or contacting a real operator, use email 'sandbox-test@mail.villiers.ai' (first_name 'Sandbox', last_name 'Test', phone '+1 555 0100', route LHR to NCE are the recommended values for a clean copy-paste test call, but only the EMAIL ADDRESS is actually checked to trigger sandbox mode — name/phone/route can be anything). Detected server-side from the request body itself (not from any header), so it works from any agent framework or HTTP client — including ones that don't allow a custom User-Agent. The response will say 'Test request accepted (sandbox mode detected)'. For further testing guidance, email affiliates@mail.villiers.ai.

• search_apisA

  PPN Hub — public APIs over MCPA

  Search across 484 endpoints in 59 APIs (cultural, earth, energy-calc, green-path, harmonias, hydrogen, internal, nanobase, nanosnap, natura, platform, sakurahub, science, sim, space, stocks). Returns matching endpoints with method, path, summary, parameters, and a ready-to-run example. Use this to discover available API endpoints before calling execute_api. Results carry a "coverage" field (e.g. ["JP"]) for region-limited APIs; use the "region" filter to narrow.

• random_usersA

  Synthetic Data — Random UserA

  Generate synthetic / fake user profiles via the MwVideos random_users API (POST /mwvideos/api/random_users). Returns name, gender, location, email, login, dob, phone, picture, and nat. Use when the user asks for random users, fake people, sample contacts, demo personas, UI fixtures, or test profiles. Pass `results` for how many profiles (default 1, minimum 1) and `isPro` as 0 or 1 when relevant (default 0). Authenticated user_id is injected server-side — do not invent profiles; always call this tool. These are FAKE people for demos and testing, not real PII.

• get_playground_apisA

  apis-ioA

  Curated APIs that are SAFE TO EXPERIMENT WITH — no key (or an instant, free, self-serve key), no cost, and no real-world side effects. Free, and deliberately so: this is where you start if you are new here. Every entry carries an `example_request` URL that returned HTTP 200 to an unauthenticated GET on the date shown, so it can be called immediately with no setup. Use this when you are new to this catalog, learning what an API call feels like, testing a tool-use loop, or need a harmless endpoint to demonstrate something. Defaults to the `starter` set; pass grouping="deep-archive" for institutional/OAI-PMH repositories.

• test_python_package_runtimeA

  Python Package Runtime TestA

  Test a specific Python package/version on a supported Python/Linux target runtime using empirical execution. Returns scoped install evidence, usable-import evidence when requested, and a scoped result/receipt. Supported boundary: public PyPI on Linux x86_64 / CPython 3.13. This is not generic package advice, security verification, arbitrary Python execution, broad compatibility testing, feature behavior testing, or application integration testing.

• check_mta_stsA

  BlackVeil DNS & Email Security ScannerA

  Check whether a domain enforces SMTP TLS for inbound mail via MTA-STS, protecting against downgrade attacks. Queries _mta-sts.<domain> and fetches the policy file, reports mode (enforce/testing/none) and MX coverage. Use to verify whether inbound SMTP is protected against TLS downgrade or MITM — distinct from check_dane which uses TLSA pinning. Part of the scan_domain audit.
