Claude Code: deny. ### `cancel_compel` - 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: ```untrusted-server-text 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. ``` ### `delete_webhook` - 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: ```untrusted-server-text Delete a webhook endpoint by id. Removes the registration and stops future deliveries. ``` ### `rotate_webhook_secret` - 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: ```untrusted-server-text 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. ``` ### `stop_lighting_cue` - 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: ```untrusted-server-text Stop a live cue by its launch_id. Idempotent - the cue is marked stop-requested so REACT drops it on its next refresh. ``` ## Changes things (11) Creates or changes something that can be changed back. Claude Code: ask. ### `ack_lighting_cue` - The description's first verb is "react": a word for a change. Description, as the server wrote it: ```untrusted-server-text REACT/BAE acknowledgement for a launch_id. Idempotently records whether the executor accepted or rejected the cue and which executor observed it. ``` ### `create_compel` - The name "create_compel" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `create_compel_from_music` - The name "create_compel_from_music" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a compel from a selected Deezer preview track. If the user provides an audio file instead, upload that file and use create_compel. ``` ### `launch_lighting_cue` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `register_webhook` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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= 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. ``` ### `report_lighting_cue` - The description's first verb is "react": a word for a change. Description, as the server wrote it: ```untrusted-server-text REACT/BAE report-back for cue status, active variables, skipped bindings, capability misses, last_frame_at, and errors. ``` ### `set_lighting_cue_variables` - The name "set_lighting_cue_variables" says "set": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `start_render` - The name "start_render" says "start": a word for a change. Description, as the server wrote it: ```untrusted-server-text Start rendering a READY compel with default configuration so an agent can continue to final MP4 without opening the browser UI. ``` ### `test_webhook_delivery` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `update_webhook` - The name "update_webhook" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `upload_media` - The name "upload_media" says "upload": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Get upload instructions for media files (audio, images, video). Returns the upload URL and required headers. Requires API token authentication. ``` ## Only reads (15) Looks things up and changes nothing. Claude Code: allow. ### `get_account_credits` - The name "get_account_credits" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get the authenticated account's render-minute balance and plan: minutes remaining (free + paid), monthly allowance, plan code, and whether the quota is exceeded. Call before starting an expensive render so an agent can make cost-aware decisions. ``` ### `get_capabilities` - The name "get_capabilities" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get Compeller platform capabilities, supported features, and API version. ``` ### `get_compel` - The name "get_compel" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get the current status, progress, and details of a Compeller generation job. ``` ### `get_lighting_cue` - The name "get_lighting_cue" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch a single live lighting cue by its launch_id, including resolved variables, launch_contract, and REACT feedback. ``` ### `get_pricing` - The name "get_pricing" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get current Compeller subscription plans and pricing. ``` ### `get_rendering` - The name "get_rendering" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Get details of a specific video rendering. ``` ### `list_compels` - The name "list_compels" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List all Compeller generation jobs for the authenticated account, newest first. ``` ### `list_lighting_cues` - The name "list_lighting_cues" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the live (non-stopped) lighting cues REACT is executing, including each cue's launch_id, resolved variables, launch_contract, and feedback. Optionally scope to one stage. ``` ### `list_lighting_effects` - The name "list_lighting_effects" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the COM-497 starter lighting effects available to launch as cues (e.g. "gobo-cycle", "x-move", "dimmer-pulse"). Each effect carries an id, the capabilities it needs, and a launch_contract template. Use the returned id as effect_id for launch_lighting_cue. ``` ### `list_renderings` - The name "list_renderings" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List all video renderings for a specific compel. ``` ### `list_styles` - The name "list_styles" says "list": a word for reading.
