Retrieve a single test suite or all test suites for a project in TestRail. Set payload.action to 'one' or 'many' to specify the operation.

Get detailed information about a test case including its custom fields

Get all test cases for a project. Filter by section, API params (priority, type), or any field including custom fields via 'where'. Returns case IDs, titles, and any additional requested fields.

Get the field schema for test cases for a specific project. You should normally provide project_id to get fields applicable to your project. If you truly need all fields across all projects, you may omit project_id, but this is rarely what you want. Returns available fields with their types and options (for dropdown fields).

Update a test case in TestRail. The update operation requires knowing valid field names that are returned by get_case_fields tool. Supports partial updates — only specify the fields you want to change.

Bulk update multiple test cases with the same field values. The update operation requires knowing valid field names that are returned by get_case_fields tool. More efficient than calling update_case multiple times.

Create a new test case in TestRail. The create operation requires knowing valid field names that are returned by get_case_fields tool.

Resolve numeric reference IDs of a Multi-select case field (type ID 12) into their textual values for a specific project.

Get all sections for a project. Returns section IDs and names that can be used with add_case

Create a new section or update an existing section in TestRail. Set payload.action to 'create' or 'update' to specify the operation.

Create a new test run or update an existing one in TestRail. Set payload.action to 'create' or 'update' to specify the operation.

Retrieve a single test run or all test runs for a project in TestRail. Set payload.action to 'one' or 'many' to specify the operation.

Add an attachment to a test run in TestRail. (Deprecated: Prefer add_attachment tool). Maximum upload size is 256MB.

Add one or more test results to a test run

Add one or more test results to a test run using case IDs instead of test IDs

Get results for a specific test in TestRail.

Add an attachment to a test case or test run in TestRail. If the file_path points to a directory, it will be automatically zipped before uploading. Maximum upload size is 256MB.

Download a single attachment or list all attachments for a test case or test run in TestRail. Set payload.action to 'one' or 'many' to specify the operation.

Get all configuration groups and configurations for a project in TestRail.

Get all available test case labels (sometimes called tags) for a project. Returns label IDs and titles that can be used when creating or updating test cases.

Get all available test case priorities (e.g. Critical, High, Medium, Low). Returns priority IDs and names that can be used when creating or updating test cases.

Get all available test statuses (e.g. Passed, Failed, Blocked). Returns status IDs and names that can be used with add_result and get_tests

Get available test case templates for a project. Template IDs determine which fields are available when creating or updating test cases

Get tests for a test run, optionally filtered by status

Get active users from TestRail. Resolves active users globally or per-project. If global fetch is forbidden (for non-admin accounts), falls back to merging users across all active projects so users referenced as reviewers or assignees can be resolved.
