## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (edit_session).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 75/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 1042 tokens (~80/item across 13 items; 12 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 74/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 8% of tool parameters carry a description.
  - Structured output schemas are declared (25% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

First indexed and scored.

## MCP tools (12)

### `describe_nodes` (~60 tokens)

Discover Hyperwave node types, inputs, numeric controls, graph sources, and complete default node templates. Pass a kind to retrieve details; omit it for the compact inventory. Use these templates and stable ids in edit_session changes.

Input parameters:

- `kind` (string)

### `create_session` (~83 tokens)

Create a private temporary collaborative Hyperwave workspace, expiring after 24 hours. Returns sessionId, secret token, editorUrl, revision, and state. Share editorUrl with the user to collaborate. Keep token private. Sessions store project state, never chat prompts or analytics. Begin with read_session and edit_session; no account is needed.

Input parameters:

- `name` (string)

### `read_session` (~65 tokens)

Read the shared preset, current revision, expiry, and checkpoint summaries. Include checkpoints=true to retrieve restorable states. Always read after a conflict and before editing an old revision.

Input parameters:

- `checkpoints` (boolean)
- `sessionId` (string, required)
- `token` (string, required)

### `edit_session` (~155 tokens)

Apply one atomic, undoable batch of changes to the shared preset. Paths are field-name arrays; nodes and connections use stable element ids instead of numeric indices, e.g. [document,graphs,root,nodes,node-id,params,gain]. Use describe_nodes templates when adding nodes. Supply baseRevision from read_session. Independent concurrent changes merge; conflicting fields return SESSION_CONFLICT. Significant agent batches automatically checkpoint the previous state. Never blindly replace the whole document after a conflict.

Input parameters:

- `actor` (string)
- `baseRevision` (integer, required)
- `changes` (array, required)
- `checkpoint` (boolean)
- `label` (string)
- `sessionId` (string, required)
- `token` (string, required)

### `checkpoint_session` (~103 tokens)

Create a restorable version of the current shared preset with a short description. Also use before a substantial experiment. Checkpoints are retained in the shared version history and exported preset. Use action=rename or delete with checkpointId to manage an existing version.

Input parameters:

- `action` (string)
- `baseRevision` (integer, required)
- `checkpointId` (string)
- `label` (string)
- `sessionId` (string, required)
- `token` (string, required)

### `restore_session` (~70 tokens)

Restore a checkpoint as a new shared edit. Requires the exact current revision; preserves the current preset as a checkpoint first. Both participants see the restored state.

Input parameters:

- `baseRevision` (integer, required)
- `checkpointId` (string, required)
- `sessionId` (string, required)
- `token` (string, required)

### `wait_for_changes` (~79 tokens)

Wait up to 20 seconds for a newer shared revision. Returns changed=false on timeout; otherwise the current state. Use while collaborating with the user, then inspect their changes before the next edit.

Input parameters:

- `afterRevision` (integer, required)
- `sessionId` (string, required)
- `timeoutMs` (integer)
- `token` (string, required)

### `render_session` (~90 tokens)

Render an exact shared revision using Hyperwave's shipped WASM engine without an open browser. Returns short-lived preview WAV, wavetable WAV, and editable preset archive links. Rendering is bounded; unsupported nodes are reported rather than silently rendered as passthroughs. Open editorUrl for larger interactive renders.

Input parameters:

- `revision` (integer, required)
- `sessionId` (string, required)
- `token` (string, required)

### `close_session` (~54 tokens)

Permanently delete the temporary collaborative workspace. Save or export a preset first; downloaded and normally saved presets remain available.

Input parameters:

- `baseRevision` (integer, required)
- `sessionId` (string, required)
- `token` (string, required)

### `list_export_targets` (~60 tokens)

Read supported synthesizer import formats, steps, caveats, and primary sources. Filter by exact slug or category.

Input parameters:

- `category` (string)
- `cursor` (string)
- `limit` (integer)
- `slug` (string)

Output parameters:

- `has_more` (boolean)
- `next_cursor` (string|null)
- `targets` (array)
- `total` (integer)

### `calculate_frame_size` (~82 tokens)

Calculate packed float32 mono WAV sample count, payload bytes, total bytes, and durations. Pure calculation; no audio rendering or saved data.

Input parameters:

- `frameCount` (integer, required): Number of frames packed into the WAV
- `sampleRate` (integer, required): WAV sample-rate header, in Hz
- `samplesPerFrame` (integer, required): Samples in each single-cycle frame

Output parameters:

- `fileByteCountWithHeader` (number)
- `frameCount` (number)
- `frameDurationSeconds` (number)
- `frameDurationSecondsAtRate` (object)
- `payloadByteCount` (number)
- `sampleRate` (number)
- `samplesPerFrame` (number)
- `totalDurationSeconds` (number)
- `totalSampleCount` (number)

### `describe_wav_encoding` (~48 tokens)

Read Hyperwave's actual WAV encoder layout for float32 or pcm16 exports, including format tag, bytes per sample, channel count, and header size.

Input parameters:

- `format` (string, required)

Output parameters:

- `bitsPerSample` (integer)
- `bytesPerSample` (integer)
- `channels` (integer)
- `format` (string)
- `formatTag` (integer)
- `headerByteLength` (integer)

### What tools does the app.hyperwave.www/wavetable-tools MCP server expose?

app.hyperwave.www/wavetable-tools exposes 12 tools: describe_nodes, create_session, read_session, edit_session, checkpoint_session, and 7 more. Their descriptions and schemas cost roughly 949 tokens of context every time the server is loaded.

### Does the app.hyperwave.www/wavetable-tools MCP server require authentication?

No. We connected to app.hyperwave.www/wavetable-tools without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the app.hyperwave.www/wavetable-tools MCP server still maintained?

app.hyperwave.www/wavetable-tools is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
