User description

Part of wave-av/wave-context#48. Delivers the adk half of wave-av/wave-context#72 (the mcp-server half is wave-av/mcp-server#63).

The ADK shipped 10 tools covering streams and live production — and nothing for the fleet products that are actually in production. This adds three toolkits, taking the registry to 17 tools.

Toolkit Tools Calls
FleetToolkit wave_speak, wave_transcribe, wave_caption POST /v1/{voice,transcribe,captions} via the gateway
DispatchToolkit wave_route, wave_list_routing_profiles Dispatch POST /, GET /profilesits own host
PaymentsToolkit wave_find_paid_services, wave_payment_schemes GET /v1/mpp/services, GET /v1/{x402,mpp}/facilitator/supportedpublic

Every path is grounded in the spoke's own router, not the API spec

wave-av/api-spec declares /voice/generate, /voice/voices, /voice/clone, /transcribe/{id}, /captions/{jobId}/download, /phone/*, /podcast/*none of which exist. Each spoke owns its whole /v1 namespace with an exact-match router and 404s anything else; the gateway forwards /v1/<product> verbatim with no rewriting. Building from the spec would have shipped tools that 404. Filed as wave-av/api-spec#33; the paths here come from git show origin/main:src/api.ts in each spoke.

Worth stating plainly: phone and podcast are not buildable. wave-phone-edge and wave-podcast-edge have no api.ts at all — their src/ is favicon.ts, landing.ts, tokens.css.ts, worker.ts. They are landing shims, and neither prefix appears in the gateway routing table. No tool is claimed for either.

Three decisions worth your attention

1. wave_speak gives code the bytes and a serialiser a receipt. POST /v1/voice returns audio/mpeg. Returning the bytes is right for an SDK — discarding a response body is lossy and the caller can't recover it. But agent frameworks routinely JSON.stringify a tool result straight into a model's context, where a megabyte of serialised byte array is useless to something that cannot listen. So VoiceResult holds the real Uint8Array on .audio, and its toJSON() emits { contentType, byteLength, usage } instead. No caller has to choose.

This is the concrete answer to the open question I raised on mcp-server#63 — in MCP the tool result is text so a receipt is all that's possible, but in a TypeScript SDK we can have both.

2. PaymentsToolkit takes no API key — not an optional one, none at all. Those gateway routes are public by design, because an agent has to discover what it can buy before it holds a WAVE key. The surest way to never send a credential to an endpoint that doesn't authenticate it is to have nothing to send. Only the read half is exposed; the facilitator's verify and settle are the money-moving side and are deliberately not wrapped.

3. A separate base URL and a separate fetch path, twice. api.wave.online fronts the product spokes and the payment rails; dispatch.wave.online fronts Dispatch, which is not behind the gateway. Reusing AgentToolkit.call() would also have forced Content-Type: application/json onto content-type-sensitive spokes and — see below — swallowed every error.

Two things this fixes on the way past

AgentTool and the MCP-shape mapper move to src/tools/shared.ts so all four toolkits emit identical MCP definitions. AgentToolkit re-exports AgentTool from its original path, so import { type AgentTool } from '@wave-av/adk' resolves exactly as before — the public API is unchanged, and the smoke check asserts it.

The new toolkits throw a typed WaveToolError carrying the status and the response body verbatim. AgentToolkit.call() never checks response.ok, so it returns error bodies as though they were successful results — that's pre-existing and out of scope here, but it's why wave_find_paid_services surfacing a real 503 (below) is the intended behaviour rather than a swallowed empty list. WaveToolError is also the export the README has been advertising from @wave-av/adk/tools without it existing.

Verification

npm run type-check   # exit 0
npm run lint         # exit 0 (eslint --max-warnings 0)
npm run build        # ESM + CJS build success

Smoke check against the built output (dist/index.js, so it proves what a consumer gets) — 33/33:

=== registry ===
  ✓ AgentToolkit (pre-existing): 10 tools    ✓ FleetToolkit: 3 tools
  ✓ DispatchToolkit: 2 tools                 ✓ PaymentsToolkit: 2 tools
  total tools: 17
=== MCP shape is identical across all four toolkits ===
  ✓ AgentToolkit MCP defs unchanged in shape — wave_create_stream
=== no credential can reach the public payment rails ===
  ✓ PaymentsToolkit holds no apiKey — {"baseUrl":"https://api.wave.online"}
=== VoiceResult returns bytes to code, a receipt to a serialiser ===
  ✓ result.audio holds the real bytes        ✓ JSON.stringify omits the bytes
=== usage headers: absent must be null, never 0 ===
  ✓ usageMinutes null when absent (not 0)    ✓ a genuine 0 remaining survives as 0
=== zod validation actually fires ===
  ✓ wave_transcribe rejects a malformed url before any network call
  ✓ wave_payment_schemes rejects an out-of-enum rail (no path injection)
SMOKE PASS

Live proof — the two public tools need no key, so they ran against production:

=== wave_payment_schemes rail=x402 ===
{"supportedNetworks":[{"networkId":"eip155:8453","version":"x402@1","asset":"0x833589…2913"},
                      {"networkId":"eip155:84532","version":"x402@1","asset":"0x036cbd…cf7e"}],
 "schemes":["exact"],"facilitatorUrl":"https://gateway.wave.online/v1/x402/facilitator"}

=== wave_find_paid_services q='video transcription' ===
WaveToolError 503: {"error":"discovery_unavailable","reason":"vectorize_unbound"}

That 503 is a real production gap, not a defect in this PR — MPP service discovery is dark because its Vectorize index isn't bound (wave-av/wave-gateway#730). The toolkit raising it as a typed error rather than swallowing it is the point.

Caveats — read these

  • The five authenticated tools are not proven end-to-end. That needs a live WAVE_API_KEY, and every product call is metered, so proving them bills real money. It should be done deliberately against a test org, not incidentally in a PR.
  • This repo's tests do not run. src/__tests__/*.test.ts import vitest, but vitest is absent from package-lock.json, there is no test script, and tsconfig.json excludes the test directory. So the gate here is type-check + lint + build + the out-of-repo smoke run above. I'm filing that separately rather than smuggling a test framework into this PR — and it is why I removed the words "and are covered by tests" from the Status prose in .wave/repo.json, which was not true.
  • dist/ is tracked but intentionally not updated here. It is committed at release time (prepublishOnly rebuilds it), not per feature.
  • The framework adapters still wrap only AgentToolkit, so the new tools aren't reachable from Mastra/LangGraph/LiveKit yet. Filing that as a follow-up.
  • CI is hard-down org-wide on Actions billing (wave-av/wave-rig#174), so checks cannot run on this PR.

.wave/repo.json

Updated so the generated README covers the new surface: three new capabilities, six new resolver-verified claims, a corrected tool count (10 → 17), and a "Working with audio" section. The README prose changes ride in this PR deliberately — merging it is the review.

Note

Medium Risk
Adds authenticated HTTP clients and public payment-discovery calls with deliberate host/auth split (Dispatch vs gateway); framework adapters still only wrap AgentToolkit, so new tools are not wired into Mastra/LangGraph/LiveKit yet.

Overview
Expands the ADK from 10 stream/production MCP tools to 17 by adding three toolkits and shared toolkit plumbing, with .wave/repo.json updated to document the new surface (including a “Working with audio” section).

FleetToolkit adds gateway-backed voice, transcribe, and caption tools (wave_speak, wave_transcribe, wave_caption) using spoke-grounded paths (POST /v1/voice, /v1/transcribe, /v1/captions). VoiceResult keeps real audio on .audio while toJSON() returns a usage receipt so frameworks do not stuff megabytes into model context. DispatchToolkit targets dispatch.wave.online (not the product gateway) for wave_route and wave_list_routing_profiles. PaymentsToolkit exposes public discovery only (wave_find_paid_services, wave_payment_schemes) with no API key and does not wrap verify/settle.

src/tools/shared.ts centralises AgentTool, toMCPToolDefs, validated, readUsage, and WaveToolError (assertOk on non-2xx, isRateLimited for 429). New toolkits use this; AgentToolkit delegates MCP mapping and validation to shared code but call() still does not check response.ok (unchanged). Root and tools barrel exports include the new classes and helpers.

Summary by cubic

Previously, the ADK exposed 10 stream and production tools; it now exposes 17 across fleet media, Dispatch routing, and public payment discovery.

  • FleetToolkit targets gateway POST /v1/voice, /v1/transcribe, and /v1/captions, returning audio bytes while serializing speech results as compact receipts.
  • DispatchToolkit uses dispatch.wave.online for POST / and GET /profiles; PaymentsToolkit uses public MPP/x402 discovery routes without credentials.
  • Fleet and Dispatch calls may be metered; Fleet results expose usage and rate-limit headers, while payment tools omit money-moving verify and settle operations.
  • Shared validation and MCP mapping preserve the existing AgentToolkit API, and new toolkit failures throw WaveToolError with the response status and body.
  • .wave/repo.json now documents the 17-tool surface and retains the current CLI and test-status facts from main; framework adapters still expose only AgentToolkit.

Verification

  • Type-checking, linting, building, and the built-output smoke check pass (33/33).
  • Production payment checks returned supported x402 networks, while service discovery surfaced the known 503 vectorize_unbound response.
  • Repository unit tests have no runnable script or dependency, and authenticated calls were not run to avoid metering real usage.

Written for commit b93de50. Summary will update on new commits.

Adds the shipped WAVE surface the ADK was missing: the voice/transcribe/captions product spokes (FleetToolkit), Dispatch model routing (DispatchToolkit), and the read half of the x402/MPP agent-payment rails (PaymentsToolkit). Registry goes 10 -> 17 tools.

Every path comes from each spoke router at origin/main, not api-spec/openapi.yaml, which over-declares endpoints that 404 in production (wave-av/api-spec#33).

AgentTool and the MCP-shape mapper move to src/tools/shared.ts so all four toolkits emit identical MCP definitions; AgentToolkit re-exports AgentTool from its original path, so the public API is unchanged.

Flagging a problem with this PR's base that I found after opening it.

This repo is not the one that publishes @wave-av/adk. It sits at 1.0.2; npm serves 1.0.14, built from wave-av/sdkssdk-typescript/packages/adk. Full evidence and the decision needed are in wave-av/sdks#42.

Two consequences for this PR:

  1. Merging it would not ship these toolkits to anyone. The work is sound — 33/33 smoke checks, live-proved payment tools, type-check/lint/build clean — but it lands in a fork.
  2. One of its stated caveats is wrong because the fork is wrong. I wrote that dist/ here contains only index.js/index.cjs and that the subpath exports are unbuilt. That is true of this repo and false of the shipped package, which builds all six subpath entries. That claim comes from this repo's .wave/repo.json, which describes the fork rather than the product.

If sdks becomes the home (the likelier call), this needs re-basing onto sdk-typescript/packages/adk — mechanically straightforward, since the four new files are self-contained and the only edits to existing files are the AgentTool/toMCPTools extraction in AgentToolkit.ts and the two barrel exports. The .wave/repo.json half would need reworking against whatever SSOT sdks uses.

Not re-basing it unilaterally — that decision belongs with wave-av/sdks#42. Holding here.

Resolves three content conflicts in .wave/repo.json, all of them the same
shape: this branch and main both rewrote the SSOT facts, for different and
compatible reasons. Both sides are kept.

1. purpose / description -- main rewrote purpose around the WAVE positioning
   ("media infrastructure for the agentic internet") and added a new
   description field. This branch had rewritten the same string to describe
   the four toolkits it adds. Kept mains framing and its new field, with the
   tool facts updated to what this branch actually ships.

2. claims[] -- main corrected cli-bin-declared: the CLI is now really built,
   so bin points at ./dist/cli/index.js rather than the older index.mjs that
   was never present in dist/. That correction is newer and true, so mains
   line wins; this branchs six new toolkit claims are appended alongside it
   rather than being dropped by taking one side wholesale.

3. sections[] Status prose -- same merge: mains corrected CLI and test-file
   wording, with this branchs toolkit and tool-count wording.

Grounded, not asserted. The 17-tools-across-4-toolkits figure was counted from
the merged source: AgentToolkit 10, FleetToolkit 3, DispatchToolkit 2,
PaymentsToolkit 2. Mains CLI facts were re-checked against the merged tree --
src/cli/index.ts exists, the build script compiles it, and package.json bin is
./dist/cli/index.js. All 14 claim resolvers were then run against the working
tree and all 14 resolve.

The file parses as JSON, and no main-only file was dropped by the merge.

CodeAnt Nitpicks

2 code suggestions

1. Malformed or empty usage headers become NaN or 0, despite the declared number-or-null type, allowing invalid metering data into tool results.

Type error · src/tools/shared.ts:76-77


2. The advertised MCP schema omits Zod constraints such as URL formats, enum values, minimums, and maximums, so clients can generate calls that handlers reject.

Resolve the publishing source before advertising this API.

These claims describe four toolkits and 17 tools as the public @wave-av/adk surface. The PR objective states that this repository is not the repository used to publish that package, and npm serves a different version. Merging these exports and metadata here will not make the documented tools available to consumers and can leave the published package inconsistent with .wave/repo.json.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Neither new toolkit bounds its outbound request. Both toolkits call fetch with no timeout and no AbortSignal. If WAVE Dispatch or the gateway stalls, the agent tool call hangs for the platform default. Add a configurable timeout and apply it at both call sites, ideally through one shared helper in src/tools/shared.ts.

  • src/tools/DispatchToolkit.ts#L45-L52: add timeoutMs to DispatchToolkitConfig and pass signal: AbortSignal.timeout(this.timeoutMs) in call.
  • src/tools/PaymentsToolkit.ts#L43-L43: add timeoutMs to PaymentsToolkitConfig and pass the same signal in publicGet.

🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Add a timeout and cancellation to the gateway request.

post calls fetch with no AbortSignal and no timeout. transcribe and caption trigger a server-side media fetch and a full STT run, so these requests are long-running. If the connection stalls, the returned promise never settles, and the public methods give the caller no way to cancel.

Accept an optional signal on speak, transcribe, and caption, and pass a default deadline through AbortSignal.timeout.

-  private async post(tool: string, path: string, init?: RequestInit): Promise<Response> {
+  private async post(tool: string, path: string, init?: RequestInit): Promise<Response> {
     const response = await fetch(`${this.baseUrl}${path}`, {

       headers: { Authorization: `Bearer ${this.apiKey}`, ...init?.headers },

Bound the error body before buffering it.

response.text() buffers the complete non-2xx body. The later 500-character message limit does not limit allocation. A large gateway error response can exhaust memory in every toolkit that uses assertOk. Read a bounded number of bytes, cancel the remaining stream, and mark the stored body as truncated.
