Tools 48 found in our last check
get_workspaceThe workspace this key belongs to: its id, name and plan, and this period's usage.
get_usagePlan, runs used this billing period, included runs, extra-run packs and runs left.
get_networkHow our browsers reach your sites: the static addresses to allow-list, the country they browse from, and the countries available.
set_browse_fromChoose the country our browsers and devices reach your sites and app servers from (web and app tests), or automatic: the site's own country (an app test then uses our default country).
list_projectsThe projects in this workspace (a project groups the tests of one site or app).
get_projectOne project.
create_projectCreate a project, for example one per site or app.
update_projectRename a project or change its description.
delete_projectArchive a project: its tests stop running; past runs stay in the run history.
list_testsThe tests of a project, each with its latest run.
get_testOne test: its start address, requirement, plan, options and latest run.
create_testCreate a test of a website (url) or of an app (platform android or ios, and appId; device phone or tablet and osVersion, default a phone on the latest OS). Pass `plan` (from plan_test, after the requester confirmed it): it is stored as the approved checklist and the tester follo…
update_testChange a test: its title, start address, requirement, plan or options. Only the fields you pass change; within `options`, only the options you pass change and the others keep their values.
duplicate_testCopy a test under a new title: the test's info is copied over (start address, requirement, plan, options and files). Its run history and schedules stay with the original. The copy counts toward the plan's test limit. Without `title` it is named "<original title> (copy)". Pass `p…
delete_testArchive a test: it stops running; past runs stay in the run history.
plan_testHave the assistant draft a test from a plain-language description, or revise a plan, without saving anything. Returns the proposed steps, checks, values to record, assumptions and any questions only the requester can answer. Show the plan to the requester; to change it, call aga…
list_test_filesFiles a test can upload during its steps (for example an import file).
add_test_fileAdd a file the tester can upload during the test: up to 25 MB, up to 10 files per test. REST: send the raw bytes as the body with the file name in the X-File-Name header (or ?name=), or JSON {name, contentBase64}. MCP: name and contentBase64. A file with the same name replaces t…
delete_test_fileRemove one of a test's files.
list_credentialsThe sign-in accounts stored for a project: names, usernames and sites. Passwords are never returned.
add_credentialStore a sign-in account the tester can use. The password is encrypted, never returned, and never sent to the tester's AI: the tester types it. Tests refer to the account by name ("Sign in as the account \"customer\""). Through MCP the password passes through your AI agent: prefe…
delete_credentialDelete a sign-in account. Tests that sign in with it stop running until it is added again or they are edited.
list_endpointsCalls into your own systems the tester may make during a run (for example "create a voucher"). Headers are never returned.
add_endpointAdd a call the tester may make into your system. It sees only the name, the description and what the call returned. Using endpoints in a run needs a paid plan. bodyTemplate may contain {{param}} placeholders the tester fills in. Headers (for example Authorization) are encrypted…
delete_endpointDelete an endpoint.
run_testStart a run of one test. Runs take minutes: poll get_run until final is true. watchUrl opens the run live without signing in. App tests run the newest build of their app unless buildId names another (see list_builds). watchUrl is a view-only link anyone can open (no sign-in) to…
run_projectStart a run of every test in a project (a suite). Each started run has a watchUrl to watch it live without signing in. buildIds: builds to use; each app test runs the one of its own app. Tests that could not start are listed in skipped with the reason. REST: send an Idempotency-…
list_runsRecent runs, newest first, optionally for one test or project or with one status; or the runs with the given ids.
get_runA run: its status, and once final the verdict, the headline, each check's result with the reason, the values read, and links to the video, screenshots and the result page.
wait_runWait up to seconds (default 25, at most 55) for a run to finish, then return it: one call instead of polling get_run every few seconds. Call it again while final is false. The answer comes back the moment the run is final (verdict, checks and evidence in), or when the time is up…
stop_runStop a queued or running run. A run you stop is not counted.
create_watch_linkA view-only link to watch a run live and read its result, with no sign-in, valid while it runs and for some hours after. Runs started here get one automatically; this makes another, or one for a run started from the web app. The link shows the live screen, the steps and checks s…
revoke_watch_linkTurn off every watch link of a run straight away.
list_share_linksThe share links made for a run, with when they expire and how often they were opened.
create_share_linkA read-only link to a run's result, replay and video that anyone can open without signing in, until it expires.
delete_share_linkTurn off a share link straight away.
list_schedulesWhen tests run by themselves: every schedule in the workspace, or those of one test or project.
create_scheduleRun a test by itself: on chosen weekdays, or monthly on a day, at a time in a time zone. Each scheduled run counts like any other run.
update_schedulePause or resume a schedule.
delete_scheduleDelete a schedule.
list_devicesThe phones and tablets app tests can run on, and their OS versions (latest first). Pass device and osVersion to create_test, update_test, run_test or run_project. A new app test runs on a phone with the latest OS unless you choose otherwise; the version is saved with the test, s…
list_buildsThe app builds uploaded to a project (Android .apk, iOS Simulator .app zipped), newest first, with the largest size and part size for uploads.
get_buildOne build: its app id, version, status and any warnings.
find_buildIs this build already uploaded? Looks up the project's newest ready build by the file's sha256, else by a native fingerprint; build is null when neither matches. A sha256 match means the exact file is uploaded: run it with run_test {buildId} / run_project {buildIds} instead of u…
create_build_uploadStart a build upload and get signed links that upload the file without an API key: run the returned command in a shell, or PUT each part and POST complete to the links. The build is then checked and ready to run. For AI agents: tool arguments cannot carry a build, so hand the by…
import_buildFetch a build from an https link (an EAS, Bitrise, S3 or GitHub artifact link, up to the build size limit) into the project; it is checked and ready to run. Nothing to upload from your side. The link must be https to a public host name; up to 3 redirects are followed. headers (o…
complete_build_uploadFinish the upload with every part's etag. The build is checked (app id, version, whether our devices can run it) and returned. Use the returned build.id in run_test {buildId} or run_project {buildIds} to run the new build. Uploading alone does not start a run. The command from c…
delete_buildDelete a build. Runs that used it keep their results; a build a test pins cannot be deleted.
