AppSignal (BYOK) lets an AI assistant read your own AppSignal data through the AppSignal API with a key you supply (AppSignal personal API token). Read-only: 10 tools (verify_token, list_error_samples, list_performance_samples, get_sample, list_markers, list_metric_names, get_metric_type_and_tags, query_metric_timeseries, query_metric_by_namespace, get_deploy_statistics). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to appsignal.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by AppSignal. AppSignal and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the AppSignal API (appsignal.com) with a BYOK key; documentation: https://docs.appsignal.com/api. Endpoints checked against that documentation on 2026-10-16.
