+ Supported in ADKPython +
+ +The [Oruk MCP server](https://oruk.ai/docs/mcp) connects your ADK agent to +transcription and vocal-expression analysis for prerecorded English audio. +It runs remotely at `https://oruk.ai/mcp` using Streamable HTTP, so you do not +need to install an Oruk server or SDK locally. + +## Use cases + +- **Transcribe recordings**: Turn a voice note or other recording into text + with segments and word timings. +- **Review vocal delivery**: Inspect emotion and speaking-style scores for + audio segments, optionally alongside a transcript. +- **Select a speech model**: Read the current model catalog and supported + label sets before processing audio. + +## Prerequisites + +- Python 3.10 or later and ADK, configured for Gemini as described in the + [Python quickstart](/get-started/python/). +- An Oruk API key from your [Oruk account](https://oruk.ai/account). Oruk also + offers a temporary, no-account MCP trial with three requests and a 30-minute + key, subject to availability. See the [MCP setup guide](https://oruk.ai/docs/mcp) + for that separate setup flow. +- An English recording you have permission to send to Oruk. The example uses + a public sample URL. For your own recordings, use a publicly fetchable URL + or the base64 input described below. + +## Use with agent + +=== "Python" + + === "Remote MCP Server" + + Install ADK with its MCP dependencies: + + ```shell + python -m pip install "google-adk[mcp]" + ``` + + Create an agent with `adk create oruk_agent`, following the Python + quickstart to configure its Gemini credentials. Add the Oruk key to + `oruk_agent/.env` and keep that file out of version control: + + ```dotenv title="oruk_agent/.env" + GOOGLE_API_KEY=YOUR_GEMINI_API_KEY + ORUK_API_KEY=YOUR_ORUK_API_KEY + ``` + + Replace `oruk_agent/agent.py` with the following code: + + ```python title="oruk_agent/agent.py" + import os + + from google.adk.agents import Agent + from google.adk.tools.mcp_tool import McpToolset + from google.adk.tools.mcp_tool.mcp_session_manager import ( + StreamableHTTPConnectionParams, + ) + + oruk_api_key = os.environ["ORUK_API_KEY"].strip() + if not oruk_api_key: + raise ValueError("Set ORUK_API_KEY before running the agent.") + + root_agent = Agent( + model="gemini-flash-latest", + name="oruk_agent", + instruction=( + "Help users analyze prerecorded English speech.

Explain the returned + vocal-expression scores without inferring the speaker's feelings. + ``` + + The connection sends the Oruk key in an HTTP header. The tool filter + exposes only speech analysis and model discovery, excluding account + usage and trial-key creation. The Gemini credential is separate from + the Oruk credential. + +## Available tools + +Tool | Description +---- | ----------- +`oruk_analyze_speech` | Return a transcript, emotion scores, speaking-style scores, and segments. +`oruk_transcribe_audio` | Return an English transcript with segments and word timings. +`oruk_analyze_tone` | Return emotion and speaking-style scores without requesting a transcript. +`oruk_list_models` | Read the current model catalog, label sets, and plan information without an API key. + +The server additionally exposes `oruk_check_usage`, `oruk_create_trial_key`, +and `oruk_get_started`. These are intentionally excluded from this example. +See the [complete tool list](https://oruk.ai/docs/mcp) before adding them to +an agent's tool filter. + +## Configuration + +For audio tools, supply exactly one of these inputs: + +- **Public URL**: Set `audio_url` to a publicly fetchable audio file, up to + 30 MB. Oruk fetches this URL; it cannot access a path on your computer. +- **Inline bytes**: Set `audio_base64` to base64-encoded audio, up to 8 MiB + decoded, and provide a `filename` with the correct extension. Avoid placing + large base64 strings in a chat prompt. + +The server accepts WAV, FLAC, MP3, M4A, OGG, and WebM, with a maximum duration +of 60 minutes. This integration covers prerecorded English speech, not live +microphone streaming. The default model is `oruk-resonance`; check +`oruk_list_models` for current model capabilities. + +Results include text content and machine-readable `structuredContent`. +The default `detail: "compact"` returns the top scores and condensed segments. +Use `detail: "full"` for all labels, segments, and timings returned by the +underlying API, subject to the MCP response-size limit. This does not expose +scores for labels that the API did not return. + +Scores describe vocal expression and delivery. They are independent and do not +sum to one. They are not probabilities of private feelings and should not be +used to infer intent, identity, or a diagnosis. See Oruk's +[score interpretation guide](https://oruk.ai/docs#labels). + +A tool response with `isError: true` is a failure, even when the HTTP request +succeeds. Check the error before using the result. An expired key, exhausted +trial, inaccessible audio URL, or unsupported input can prevent analysis. +Usage and reference cost fields are not subscription invoice charges; actual +billing follows the configured Oruk plan. + +## Additional resources + +- [Oruk MCP documentation](https://oruk.ai/docs/mcp) +- [Oruk MCP connection metadata](https://github.com/Oruk-AI/oruk-mcp) +- [MCP tools in ADK](/tools-custom/mcp-tools/)
