bugsnag_list_span_groups

List span groups (operations) tracked for performance monitoring Parameters: - projectId (string): Unique identifier of the project. This is optional if a current project is set and is used to set the current project for BugSnag tools. - sort (enum): Field to sort by - direction (enum): Sort direction for ordering results (default: "desc") - perPage (number): How many results to return per page. (default: 30) - starredOnly (boolean): Show only starred span groups - nextUrl (string): URL for retrieving the next page of results. Use the value in the previous response to get the next page when more results are available. Only values provided in the output from this tool can be used. Do not attempt to construct it manually. - filters (record<string, array>): Apply filters to narrow down the span group list. Use the List Trace Fields tool to discover available filter fields. Time filters support extended ISO 8601 format (e.g. 2018-05-20T00:00:00Z) or relative format (e.g. 7d, 24h). (default: {"span.since":[{"type":"eq","value":"7d"}]}) Use Cases: 1. View all operations being tracked for performance 2. Find slow operations by sorting by duration metrics 3. Filter to starred/important span groups Examples: 1. List slowest operations json { "sort": "duration_p95", "direction": "desc", "perPage": 10 } Expected Output: Array of span groups sorted by 95th percentile duration 2. List starred span groups with filtering json { "starredOnly": true, "filters": { "span_group.category": [ { "type": "eq", "value": "full_page_load" } ] } } Expected Output: Array of starred span groups filtered by category Hints: 1. Span groups represent different operation types (page loads, API calls, etc.) 2. Use sort by duration_p95 or duration_p99 to find the slowest operations 3. Star important span groups for quick access 4. Use nextUrl for pagination. It is categorised as a Read tool in the SmartBear MCP MCP Server, which means it retrieves data without modifying state.

bugsnag_list_span_groups accepts 7 parameters: sort, filters, nextUrl, perPage, direction, projectId, starredOnly. The full parameter table on this page comes from the server's own tool schema.
