Deletes or cancels 4Removes, cancels or revokes something.Claude Code: deny

cancel_compelCancel an in-progress compel.No findings
Why it is in this group
- The name "cancel_compel" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Cancel an in-progress compel. Dequeues it if still queued, otherwise cancels any active external (AI provider) tasks and transitions it to CANCELLED. Idempotent - cancelling an already-CANCELLED compel succeeds. Use to stop a mis-prompted or runaway job before it consumes more render minutes.
Annotations the server declares
- title: Cancel a compel
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: true
delete_webhookDelete a webhook endpoint by id.No findings
Why it is in this group
- The name "delete_webhook" says "delete": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Delete a webhook endpoint by id. Removes the registration and stops future deliveries.
Annotations the server declares
- title: Delete webhook
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: true
rotate_webhook_secretMint a new HMAC-SHA256 signing secret for a registered webhook endpoint.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Mint a new HMAC-SHA256 signing secret for a registered webhook endpoint. The previous secret is invalidated immediately - integrators must update their receiver before the next compel terminal event fires. Returns the new secret exactly once; store it on receipt.
Annotations the server declares
- title: Rotate webhook secret
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: true
stop_lighting_cueStop a live cue by its launch_id.No findings
Why it is in this group
- The name "stop_lighting_cue" says "stop": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
Stop a live cue by its launch_id. Idempotent - the cue is marked stop-requested so REACT drops it on its next refresh.
Annotations the server declares
- title: Stop lighting cue
- readOnlyHint: false
- destructiveHint: true

Changes things 11Creates or changes something that can be changed back.Claude Code: ask

ack_lighting_cueREACT/BAE acknowledgement for a launch_id.No findings
Why it is in this group
- The description's first verb is "react": a word for a change.
Description, as the server wrote it
REACT/BAE acknowledgement for a launch_id. Idempotently records whether the executor accepted or rejected the cue and which executor observed it.
Annotations the server declares
- title: Ack lighting cue
- readOnlyHint: false
- destructiveHint: false
create_compelCreate a Compeller generation job from primary audio media and optional reference media.No findings
Why it is in this group
- The name "create_compel" says "create": a word for a change.
Description, as the server wrote it
Create a Compeller generation job from primary audio media and optional reference media. Returns compel id, status, and links to track progress and retrieve renderings.
Annotations the server declares
- title: Create Compel from uploaded audio
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: false
create_compel_from_musicCreate a compel from a selected Deezer preview track.No findings
Why it is in this group
- The name "create_compel_from_music" says "create": a word for a change.
Description, as the server wrote it
Create a compel from a selected Deezer preview track. If the user provides an audio file instead, upload that file and use create_compel.
Annotations the server declares
- title: Create Compel from music search
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: false
launch_lighting_cueLaunch a starter lighting effect onto a stage as a live cue (e.g.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Launch a starter lighting effect onto a stage as a live cue (e.g. "gobo-cycle on the stage's 7R beams at speed 0.5"). Pass effect_id (from list_lighting_effects) and optional variables to override effect defaults. Validation is loud: an unknown effect, a launch_contract whose bindings a stage cannot render, or a missing required field is rejected. Returns the active cue including its launch_id, resolved variables, and launch_contract for REACT. REACT executes the cue per-frame; the live strobe slider stays authoritative and is never raised by a launch.
Annotations the server declares
- title: Launch lighting cue
- readOnlyHint: false
- destructiveHint: false
register_webhookRegister an HTTPS endpoint to receive signed push notifications for compel lifecycle events (compel.ready when renderable, compel.completed, compel.failed).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Register an HTTPS endpoint to receive signed push notifications for compel lifecycle events (compel.ready when renderable, compel.completed, compel.failed). Returns webhook_id and the HMAC-SHA256 signing secret exactly once - store the secret immediately, it is never returned again. Deliveries are signed via X-Compeller-Signature: sha256=<hex> over the raw body. Delivery is at-least-once: a failed delivery is retried with backoff (up to 6 attempts) and every retry carries the same X-Compeller-Event-Id, so dedupe on it.
Annotations the server declares
- title: Register webhook
- readOnlyHint: false
- openWorldHint: true
- destructiveHint: false
report_lighting_cueREACT/BAE report-back for cue status, active variables, skipped bindings, capability misses, last_frame_at, and errors.No findings
Why it is in this group
- The description's first verb is "react": a word for a change.
Description, as the server wrote it
REACT/BAE report-back for cue status, active variables, skipped bindings, capability misses, last_frame_at, and errors.
Annotations the server declares
- title: Report lighting cue
- readOnlyHint: false
- destructiveHint: false
set_lighting_cue_variablesUpdate variables on a live cue (e.g.No findings
Why it is in this group
- The name "set_lighting_cue_variables" says "set": a word for a change.
Description, as the server wrote it
Update variables on a live cue (e.g. change cycle speed or intensity mid-show). Only the variables you pass change; the rest keep their current values. Stopped cues are rejected.
Annotations the server declares
- title: Set lighting cue variables
- readOnlyHint: false
- destructiveHint: false
start_renderStart rendering a READY compel with default configuration so an agent can continue to final MP4 without opening the browser UI.No findings
Why it is in this group
- The name "start_render" says "start": a word for a change.
Description, as the server wrote it
Start rendering a READY compel with default configuration so an agent can continue to final MP4 without opening the browser UI.
Annotations the server declares
- title: Start Compel render
- readOnlyHint: false
- openWorldHint: false
- destructiveHint: false
test_webhook_deliverySynchronously POST a synthetic webhook.test event to a registered endpoint.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Synchronously POST a synthetic webhook.test event to a registered endpoint. Uses the same HMAC-SHA256 signature as real deliveries, runs the standard URL safety check at delivery time, and returns {webhook_id, event_id, event_type, delivered, response_status, response_body_preview, latency_ms, error?}. Ignores the endpoint's events subscription - test delivery is always on-demand. Use this to verify your integration before relying on compel.completed / compel.failed events.
Annotations the server declares
- title: Test webhook delivery
- readOnlyHint: false
- openWorldHint: true
- destructiveHint: false
update_webhookUpdate one or more mutable fields on a registered webhook endpoint: url, events, active.No findings
Why it is in this group
- The name "update_webhook" says "update": a word for a change.
Description, as the server wrote it
Update one or more mutable fields on a registered webhook endpoint: url, events, active. At least one of these must be provided. Validation mirrors register_webhook (https-only, <= 2048 chars, URL safety blocklist). Returns the updated endpoint (secret is never returned by this tool - use rotate_webhook_secret for that).
Annotations the server declares
- title: Update webhook
- readOnlyHint: false
- openWorldHint: true
- destructiveHint: false
upload_mediaGet upload instructions for media files (audio, images, video).1 finding
Why it is in this group
