About MCP Server By TestMu AI

TestMu AI MCP Server lets developers run, debug, and triage tests through natural language directly from their IDE (Cursor, Claude, GitHub Copilot, and other MCP clients). It exposes five tools — HyperExecute (test orchestration + YAML config), Automation (debug failures via logs), SmartUI (visual regression), Accessibility (WCAG/a11y checks), and Test Manager (AI test-case generation) — bringing TestMu AI's testing cloud into your agentic workflow. Connect via mcp.lambdatest.com/mcp with OAuth.

List all Test Manager projects the authenticated user is allowed to see. Supports keyword search and pagination.

Find test cases in a project by filters (folder, priority, automation status, type, tags) and/or search (matches test case ID like TC-123, or title; minimum 3 characters) — returns summaries. Filters combine (AND). Pass case_id instead to get one case's full detail (steps, BDD scenarios, field values).

Get a folder tree. Test Manager keeps three folder types: Test Cases and Test Runs folders (per project — pass project_id) and Modules folders (organization-level, since modules are shared across projects — no project_id needed). Pick with the tree parameter (default: test-cases). New test-case/test-run folders can be created with tm_create_folder.

List the organization's reusable step Modules (modules are org-level, shared across projects — the same list as the Modules page). Supports name search and pagination. Reference a module by id when creating or editing a test case to include its steps (the Module itself is never changed).

List saved run Configurations (reusable platform / browser / OS / device setups). To apply one to a run, pass the configuration's TOP-LEVEL id to tm_create_test_run or tm_update_test_run as configuration_id (NOT the nested environments[].environment_id). Pass run_type to see only the configurations usable for that run type (kaneai vs manual). Each test instance carries exactly one configuration. Configurations are created by humans in the Test Manager UI.

Pass run_id to get one test run's detail plus its result summary (instance counts by status — passed / failed / skipped / not started / in progress — and pass rate). Otherwise pass project_id to list runs with optional filters. Every returned run carries run_type ("kaneai" or "manual") identifying KaneAI runs — the backend stores KaneAI runs with type "Manual" (result-entry mode), so use run_type, not type, to tell them apart.

Pass milestone_id to get one milestone's detail and live completion progress. Otherwise pass project_id to list the project's milestones.

Test coverage for a project — overall and per folder — computed live from the project's test cases (matches the Test Cases screen). Also answers requirement / traceability coverage: pass jira_id (any Jira issue key, e.g. TE-123 — a requirement, user story, epic, ticket or bug) to get that item's test coverage (the test cases linked to it and how many are automated; zero linked cases = uncovered). For a set of requirements, call once per Jira key. A scope with no test cases returns all zeros.

Create a new Test Manager project. Project & Org Instructions (Memory Layer) stay managed in the UI. Deleting projects is not available through this connection.

Update a project's name, description or tags (fields are merged — only what you pass changes). Project & Org Instructions stay managed in the UI.

Create a folder — in a project's Test Cases tree (default) or Test Runs tree (pass project_id), or in the organization-level Modules tree (no project_id needed; module folders are shared across projects). Optionally nest it under an existing parent folder to build folder trees. Deleting folders is not available through this connection.

Rename a folder, change its description, or move it under a different parent folder. Works on all three folder types: per-project Test Cases (default) and Test Runs trees, and the organization-level Modules tree. Moves of test-cases/test-runs folders require project_id; module folders need none.

Generate structured test cases from a requirement or prompt using the Test Manager AI generator (applies the project's Memory Layer — Project & Org Instructions — automatically) and file them into the chosen folder. Requirement documents, specs, spreadsheets or screenshots can be attached via files to ground the generation. Volume = test_scenario_limit × per_scenario_test_cases_limit, capped at 50 per call. By default all generated cases are saved into the folder (one sub-folder per scenario); pass auto_save=false to review before saving. The call returns FAST with a request_id (and a browser progress URL) — generation takes ~30-90s in the background; call this tool again with just request_id to check progress, fetch results, or save. Note: consumes AI generation credits.

Create a single test case in a project folder, with optional steps and references to existing step Modules (module steps are included; the Module itself is unchanged). For creating many cases from a requirement, prefer tm_generate_test_cases.

Edit an existing test case (fields are merged — only what you pass changes). test_steps, when given, REPLACE the case's steps; module_ids append module reference steps. Deleting test cases is not available through this connection.

Create a test run from chosen test cases — manual (default) or KaneAI (run_type: "kaneai"). Each included test case becomes a TEST RUN INSTANCE — the executable copy of that test inside the run, which carries its own status, remarks and exactly one Configuration. The cases must match the run type: KaneAI runs only take KaneAI-authored cases with completed code generation; manual runs only take manual cases. Optionally attach existing milestones, file into a run folder, and apply a Configuration to all instances (KaneAI configurations must be compatible with each case's platform — web/mobile-app/mobile-browser and iOS/Android).

Update an open test run — overall status (Passed / Failed / Skipped / In Progress), title, objective, milestones, folder, add test cases (each added case becomes a new test run instance; cases must match the run's type — KaneAI or manual), apply a Configuration to the run's instances (configuration_id; on KaneAI runs it must be kane-supported and platform-compatible with the targeted cases), toggle sequential execution (KaneAI runs), or archive it. Only open (active) runs can be updated; a closed/archived run returns a clear message. Adding cases/milestones appends, never replaces.

Record execution results on a MANUAL run's TEST RUN INSTANCES (the per-run copies of each test case) — max 500 per request, all-or-nothing (larger requests are rejected with nothing recorded). Manual runs only: KaneAI run results are recorded by KaneAI executions, so manual entry on a KaneAI run is rejected. Target an instance by instance_id, or just pass test_case_id and the instance is resolved automatically. Valid statuses: Passed, Failed, Skipped, Not Started (terminal — run-level "In Progress" is set via tm_update_test_run). Re-recording a step status replaces its result: an omitted step remark is cleared; response echoes per-step outcomes. Optional remarks and assignee per result, and per-step results via steps[] (mark individual test steps / BDD scenario rows Passed/Failed/Skipped with remarks, like the UI's per-step Mark Status). Note: this sets INSTANCE statuses; the run's overall status is set separately via tm_update_test_run.

Create a milestone in a project (status: Open), optionally with description, start/end dates, tags, and existing runs attached.

Update a milestone — title, description, dates, tags — or change its status (e.g. mark it Completed). Deleting milestones is not available through this connection.

Link a test case, test run, or a run result (instance) to a Jira issue (requirement / user story / epic / bug) — linked test cases are what give the issue its test coverage and traceability. Linking a result also links its case and run. Requires the Jira integration to be set up for the organization — otherwise a clear "set up Jira first" message is returned.

Link a test case, test run, or a run result (instance) to an Azure DevOps work item (requirement / user story / bug) by its URL — linked test cases are what give the work item its test coverage and traceability. Requires the Azure DevOps integration to be set up for the organization — otherwise a clear "set up Azure DevOps first" message is returned.

Retrieve the full accessibility scan report for a completed scan by scan ID.

Retrieve the list of accessibility issues found in a completed scan. Optionally filter by severity.

Upload screenshots to LambdaTest SmartUI for visual regression comparison. Supports PNG, JPEG, and JPG formats. Use projectToken from your SmartUI project settings.

Retrieve a list of HyperExecute jobs for the account with optional filtering by status.

Delete a HyperExecute job by job ID.

Retrieve all artifacts or categorized errors for a HyperExecute job or task.

Get an authenticated download URL (plus size/status metadata) for a specific HyperExecute job artifact. Requires artefactName (from getHyperExecuteJobArtifacts); optionally scope to a task with taskId. Returns a URL to fetch with your LambdaTest credentials rather than the raw file bytes.

Get details for a specific artifact within a HyperExecute job.

Retrieve the stages of a HyperExecute task (cache/prerun/scenario/etc.). Pass a stageId to return just that one stage. Stages are keyed by their parent task, so taskId is required.

Retrieve logs for a HyperExecute stage. (UNDOCUMENTED - may change without notice)

Retrieve tasks for a HyperExecute stage. (UNDOCUMENTED - may change without notice)

Retrieve details for a HyperExecute task by task ID. (UNDOCUMENTED - may change without notice)

Retrieve logs for a HyperExecute task. (UNDOCUMENTED - may change without notice)

Stream live output from a running HyperExecute job. (UNDOCUMENTED - may change without notice)

Perform a full analysis of a HyperExecute job: fetches job info, sessions, traverses all tasks → scenario stages → console logs, and returns a structured report with test results, per-scenario logs, and pass/fail statistics. Use this for questions like "which tests failed and why" or "show me the console logs for job X".
