Retrieve the 'current' project on which tools should operate by default. This allows BugSnag tools to be called with no projectId parameter. **Toolset:** Projects **Parameters:** None **Use Cases:** 1. Understand if a current project has been set **Hints:** 1. If a project is returned, it can be assumed that the user expects interactions with BugSnag tools to refer to this project 2. If this tool returns no current project then other BugSnag tools will require an explicit project ID parameter 3. Call the List Projects tool to see all projects that the user has access to. Get the project ID from this list either by asking the user for the project name or slug 4. You might find a BugSnag API key in the user's code where they configure the BugSnag SDK that can be matched to a project 'apiKey' field from the project list

This is optional if a current project is set and is used to set the current project for BugSnag tools. - filters (record<string, array>): Apply filters to narrow down the error list. Use the List Project Event Filters 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: {"event.since":[{"type":"eq","value":"30d"}],"error.status":[{"type":"eq","value":"open"}]}) - sort (enum): Field to sort the errors by (default: "last_seen") - direction (enum): Sort direction for ordering results (default: "desc") - perPage (number): How many results to return per page. (default: 30) - 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. **Use Cases:** 1. Debug recent application errors by filtering for open errors in the last 7 days 2. Generate error reports for stakeholders by filtering specific error types or severity levels 3. Monitor error trends over time using date range filters 4. Find errors affecting specific users or environments using metadata filters **Examples:** 1.

Get the 10 open errors with the most users affected in the last 30 days ```json { "filters": { "event.since": [ { "type": "eq", "value": "30d" } ], "error.status": [ { "type": "eq", "value": "open" } ] }, "sort": "users", "direction": "desc", "perPage": 10 } ``` Expected Output: JSON object with a list of errors in the 'data' field, a count of the current page of results in the 'count' field, and a total count of all results in the 'total' field 3. Get the next 50 results ```json { "nextUrl": "https://api.bugsnag.com/projects/515fb9337c1074f6fd000003/errors?base=2025-08-29T13%3A11%3A37Z&direction=desc&filters%5Berror.status%5D%5B%5D%5Btype%5D=eq&filters%5Berror.status%5D%5B%5D%5Bvalue%5D=open&offset=10&per_page=10&sort=users", "perPage": 50 } ``` Expected Output: JSON object with a list of errors, with a URL to the next page if more results are available and a total count of all errors matched **Hints:** 1. Use List Project Event Filters tool first to discover valid filter field names for your project 2. Combine multiple filters to narrow results - filters are applied with AND logic 3. For time filters: use relative format (7d, 24h) for recent periods or ISO 8601 UTC format (2018-05-20T00:00:00Z) for specific dates 4. Common time filters: event.since (from this time), event.before (until this time) 5. The 'event.since' filter and 'error.status' filters are always applied and if not specified are set to '30d' and 'open' respectively 6. There may not be any errors matching the filters - this is not a problem with the tool, in fact it might be a good thing that the user's application had no errors 7. This tool returns paged results. The 'page_error_count' field indicates the number of results returned in the current page, and the 'total_error_count' field indicates the total number of results across all pages. 8. If the output contains a 'next_url' value, there are more results available - call this tool again supplying the next URL as a parameter to retrieve the next page. 9. Do not modify the next URL as this can cause incorrect results. The only other parameter that can be used with 'next' is 'per_page' to control the page size.

This is optional if a current project is set and is used to set the current project for BugSnag tools. - endpoints (array) *required*: Array of URL patterns by which network spans are grouped. Endpoints follow OpenAPI path templating syntax (https://swagger.io/specification/#path-templating) where path parameters use curly braces (e.g., /users/{id}). If you encounter colon-prefixed parameters (e.g., :userId from Express/React Router), convert them to curly braces (e.g., {userId}). Wildcards (*) can be used in domains (e.g., https://*.example.com) to match multiple subdomains. **Use Cases:** 1. Consolidate similar API endpoints into single span groups 2. Group dynamic URLs using path parameters (e.g., /api/users/{userId} groups /api/users/123, /api/users/456) 3.

Group API endpoints with path parameters ```json { "endpoints": [ "/api/users/{userId}", "/api/products/{productId}", "/api/orders/{orderId}/items/{itemId}" ] } ``` Expected Output: Success response confirming the update 2. Group endpoints with domain wildcards and path parameters ```json { "endpoints": [ "https://*.example.com/api/v1/{resourceId}", "https://api.example.com/v2/users/{userId}", "/graphql" ] } ``` Expected Output: Success response confirming the update 3. Convert colon-prefixed parameters to curly braces (e.g., from Express/React Router) ```json { "endpoints": [ "/{organizationSlug}/{projectSlug}/performance/view-load", "/api/{version}/items/{itemId}" ] } ``` Expected Output: Success response confirming the update **Hints:** 1. Use Get Network Grouping first to see current patterns 2. Use OpenAPI path templating with curly braces for path parameters: /users/{userId}, /orders/{orderId}/items/{itemId} 3. Convert colon-prefixed parameters to curly braces: :organizationSlug becomes {organizationSlug}, :projectSlug becomes {projectSlug} 4. Wildcards (*) can be used in domains to match subdomains: https://*.example.com/api 5. This replaces all existing patterns - include all patterns you want to keep 6. Well-designed patterns reduce noise in performance monitoring
