Overview

Investigate Raygun errors, deployments, user sessions, and application performance. Search Crash Reporting, RUM, and APM data, diagnose issues with full context, analyze trends, and manage application monitoring directly from Claude.

Tools

apm_issue_investigate

ChatGPT
Investigate one APM issue returned by apm_issues_search. Returns a typed metric and percentiles plus recent affected traces that can be passed to apm_trace_investigate. Slow issues use milliseconds; N+1 and chatty or overused API issues use call counts.

apm_trace_investigate

ChatGPT
Investigate one APM trace returned by apm_traces_search. Returns the trace summary, profiler threads, linked APM issues, and a bounded list containing issue-linked calls before the slowest remaining calls. Each call explains why it was selected and whether its parent is present. Raw arguments, variables, query text, and URL path values are intentionally omitted or redacted.

application_get_details

ChatGPT
Get detailed information about a specific application. Returns product-data status and plan information; set includeApiKey when the application API key is needed.

application_regenerate_api_key

ChatGPT
Generate a new API key for an application. Use this when the current API key has been compromised, needs to be rotated for security, or when integrating new services. Warning: This will invalidate the existing API key immediately.

applications_list

ChatGPT
List applications available to the current user. Use this to discover applications you have access to, find specific applications by browsing, or get an overview of your monitored applications.

customer_investigate

ChatGPT
Get a customer's profile, recent error groups (with instance counts and messages), and recent sessions. Use the Identifier returned by customers_search as the customerId parameter.

deployment_create

ChatGPT
Create a new deployment record to track a software release. Use this when deploying new versions to track releases and correlate future errors with specific deployments. Supports creation via application ID or API key.

deployment_get_latest

ChatGPT
Get the most recent deployment for an application along with its error groups. Use this to quickly assess the current production state, investigate recent deployment issues, or analyze errors in the latest release.

deployment_investigate

ChatGPT
Get comprehensive information about a specific deployment including its details and related error groups. Use this when you need to investigate deployment issues, analyze errors introduced in a release, or understand the impact of a specific deployment.

deployment_manage

ChatGPT
Update or delete a deployment record. Use this to modify deployment metadata (like version, deployment date, or comments) or remove deployment records that were created incorrectly. Updates return the modified deployment; deletes return nothing.

deployments_list

ChatGPT
List deployments for a Raygun application to track releases and software versions. Use this to browse deployment history, find specific releases, or analyze deployment patterns over time.

error_group_add_comment

ChatGPT
Add a comment to an error group. Use this to document investigation findings, resolution steps, or collaboration notes for your team. Extract identifiers from URLs like https://app.raygun.com/crashreporting/{appId}/errors/{errorGroupId}.

error_group_instances_list

ChatGPT
List lightweight instance identifiers and timestamps for an error group, newest first. Use this to compare when a group happened or select an exact instance, then call error_instance_get for full details.

error_group_investigate

ChatGPT
Get an error group together with its latest occurrence, including typed error or CSP violation details and request context. Use this after finding a group to diagnose its current failure. When given a Raygun URL like https://app.raygun.com/crashreporting/{appId}/errors/{errorGroupId}, extract the appId and errorGroupId from the path.

error_group_read_comments

ChatGPT
Read comments previously added to an error group. Use this to review prior investigation notes, collaboration context, and resolution history before taking action. Extract identifiers from URLs like https://app.raygun.com/crashreporting/{appId}/errors/{errorGroupId}.

error_group_update_status

ChatGPT
Change the status of an error group (activate, resolve, ignore, permanently ignore). Use this for error triage workflows - resolving fixed errors, ignoring known issues, or reactivating errors that need attention. Permanently ignoring with discardNewOccurrences enabled discards future occurrences. Extract identifiers from URLs like https://app.raygun.com/crashreporting/{appId}/errors/{errorGroupId}.

error_groups_list

ChatGPT
List error-group metadata without an occurrence time window or full-text matching. Use error_groups_search when looking for symptoms, code, URLs, users, tags, or custom data in occurrences.

error_instance_get

ChatGPT
Get the full typed details for one exact error instance, including an exception graph or CSP violation, request context, environment, and breadcrumbs. Use an instance identifier returned by search, investigation navigation, or error_group_instances_list.

invitation_revoke

ChatGPT
Cancel a pending team invitation that has not yet been accepted. Use this to revoke invitations sent by mistake, when access is no longer needed, or for security purposes. Only works on pending invitations - accepted invitations cannot be revoked.

invitation_send

ChatGPT
Send a team invitation to grant Raygun access to a new user. Use this to onboard new team members, grant application access, or expand your monitoring team. The recipient will receive an email with instructions to join.

invitations_manage

ChatGPT
List and review team invitations to manage user access and onboarding. Use this to see pending invitations, check invitation status, track team growth, or audit access grants. Helps with team management and security oversight.

metrics_performance_distribution_analyze

ChatGPT
Analyze performance metrics as histogram data to understand user experience distribution and variability. Returns bucketed data showing how many users experienced different performance levels (e.g., how many had 0-1s load times vs 2-3s load times). Use this to identify what percentage of users have good/bad performance and find performance outliers.

metrics_website_performance_analyze

ChatGPT
Analyze website performance metrics as time-series data to track trends, identify bottlenecks, and monitor improvements over time. Returns data points across time periods showing how performance changes. Use this to investigate performance trends, correlate with deployments, or track optimization results.

page_investigate

ChatGPT
Get basic information about a specific page (ID, URL/name, last seen). Use this to get page details needed for subsequent metrics or sessions queries. Returns the same entity information as the list but for a specific page.

pages_list

ChatGPT
List pages in a Raygun application to get page identifiers for use with sessions and metrics queries. Returns basic page information (ID, URL/name, last seen) that can be used to query specific page performance data or filter sessions by page.

session_investigate

ChatGPT
Get comprehensive session details including user environment, errors, and page views. Returns full session data with timing, location, device info, plus associated errors and page navigation. Use this to understand complete user experience, investigate problematic sessions, or analyze user journey patterns.

sessions_list

ChatGPT
List user sessions to analyze user behavior and environment data. Returns session timing, location (IP/country), device info (browser, OS, viewport), and deployment version. Use this to understand user patterns, identify problematic environments, or find sessions to investigate further.
