Tool	Type	What it does
`inngest_list_events`	read	List events List the events received in the key's environment, newest first. Events are what start functions, so this is where an investigation begins. Inngest: GET /v1/events.
`inngest_get_event`	read	Get one event Fetch a single event with its name, payload and timestamp. Inngest: GET /v1/events/{eventId}.
`inngest_list_event_runs`	read	List the runs an event started List every function run one event triggered, with each run's status. This is the hop from 'this event arrived' to 'and here is what it did'. Inngest: GET /v1/events/{eventId}/runs.
`inngest_get_run`	read	Get one function run Fetch a single function run — its status, output and error. Inngest: GET /v1/runs/{runId}.
`inngest_list_run_jobs`	read	List a run's steps List the individual steps (jobs) of one run, with their status and timing — how you find which step of a durable function failed. Inngest: GET /v1/runs/{runId}/jobs.
`inngest_list_cancellations`	read	List bulk cancellations List bulk-cancellation jobs and their progress. Inngest: GET /v1/cancellations.
`inngest_list_webhooks`	read	List webhooks List the webhook ingresses configured for the environment — the external sources that turn into events. Inngest: GET /v1/webhooks.
`inngest_get_webhook`	read	Get one webhook Fetch a single webhook ingress with its URL and transform. Inngest: GET /v1/webhooks/{webhookId}.
`inngest_create_cancellation`	write	Bulk cancel function runs Cancel every run of one function that started within a time window, optionally narrowed by an event expression. This STOPS IN-FLIGHT WORK across your production functions — scope the window tightly. Runs already finished are unaffected. Inngest: POST /v1/cancellations.
`inngest_delete_cancellation`	write	Stop a bulk cancellation Delete a bulk-cancellation job so it stops cancelling further runs. Runs it already cancelled stay cancelled. Inngest: DELETE /v1/cancellations/{cancellationId}.
`inngest_delete_webhook`	write	Delete a webhook Remove a webhook ingress. The external source stops producing events immediately. Inngest: DELETE /v1/webhooks/{webhookId}.
