Audio Transcriber
CLI or API | MCP
Version: 2.3.3
Documentation — Installation, deployment, and usage across the CLI, Python API, official documentation.
Overview
Audio Transcriber is a production-grade Agent and Model Context Protocol (MCP) server designed to interface directly with Transcribe the operator's .wav .mp4 .mp3 .flac files to text or record the operator's own audio!.
Key Features
- Consolidated Action-Routed MCP Tools: Minimizes token overhead and eliminates tool bloat in LLM contexts by grouping methods into optimized, togglable tool modules.
- Enterprise-Grade Security: Complete support for Eunomia policies, OIDC token delegation, and granular execution context tracking.
- Native Telemetry & Tracing: Out-of-the-box OpenTelemetry exports and native Langfuse tracing.
CLI or API
This agent wraps the Transcribe the operator's .wav .mp4 .mp3 .flac files to text or record the operator's own audio! API. The operator can interact with it programmatically or via its integrated execution entrypoints.
Detailed instructions on how to use the underlying API wrappers, extended schema bindings, and developer SDK references are maintained in docs/index.md.
MCP
This server use dynamic Action-Routed tools to optimize token overhead and maximize IDE compatibility.

4 action-routed tool(s) · 7 verbose 1:1 tool(s). Each is enabled unless its <DOMAIN>TOOL toggle is set false; MCP_TOOL_MODE selects the surface (intent default — the six verb-tools, granular set loaded on demand · condensed action-routed · verbose 1:1 · both). Auto-generated — do not edit.
Detailed tool schemas, parameter shapes, and validation constraints are preserved in docs/usage.md.
Dynamic Tool Selection & Visibility
This MCP server supports dynamic toolset selection and visibility filtering at runtime. This allows the operator to restrict the set of exposed tools to prevent blowing up the LLM's context window.
The operator can configure tool filtering via multiple input channels:
- CLI Arguments: Pass
--toolsor--toolsets(or their disabled counterparts--disabled-toolsand--disabled-toolsets) during startup. - Environment Variables: Define standard environment variables:
MCP_ENABLED_TOOLS/MCP_DISABLED_TOOLSMCP_ENABLED_TAGS/MCP_DISABLED_TAGS
- HTTP SSE Request Headers: Pass custom headers during transport initialization:
x-mcp-enabled-tools/x-mcp-disabled-toolsx-mcp-enabled-tags/x-mcp-disabled-tags
- HTTP SSE Request Query Parameters: Append query parameters directly to the operator's transport connection URL:
?tools=tool1,tool2?tags=tag1
When query strings or parameters are provided, an LLM-free Knowledge Graph resolution layer (using DynamicToolOrchestrator) matches query intents against known tool tags, names, or descriptions, with safe fallback and automated 24-hour background cache refreshing.
MCP Configuration Examples
Install the connector-focused
[mcp]extra. Examples useaudio-transcriber[mcp]to add FastMCP / FastAPI throughagent-connector-sdk; the required Agent Connector SDK core still carriesepistemic-graph[full]. The[agent-runtime]extra additionally enables model orchestration.
stdio Transport (local IDEs — Cursor, Claude Desktop, VS Code)
{
"mcpServers": {
"audio-transcriber-mcp": {
"command": "uvx",
"args": [
"--from",
"audio-transcriber[mcp]",
"audio-transcriber-mcp"
],
"env": {
"MCP_TOOL_MODE": "intent",
"AUDIO_PROCESSINGTOOL": "True",
"MEDIA_SIDECARTOOL": "True",
"MISCTOOL": "True",
"TRANSCRIBE_DIRECTORY": "/path/to/transcribe_directory",
"WHISPER_MODEL": "base"
}
}
}
}
Runtime references require an alias-aware launcher such as Arbora. Other launchers must omit those entries and inject the resolved values through their own runtime secret boundary.
Streamable-HTTP Transport (networked / production)
{
"mcpServers": {
"audio-transcriber-mcp": {
"command": "uvx",
"args": [
"--from",
"audio-transcriber[mcp]",
"audio-transcriber-mcp",
"--transport",
"streamable-http",
"--port",
"8000"
],
"env": {
"TRANSPORT": "streamable-http",
"HOST": "127.0.0.1",
"PORT": "8000",
"MCP_TOOL_MODE": "intent",
"AUDIO_PROCESSINGTOOL": "True",
"MEDIA_SIDECARTOOL": "True",
"MISCTOOL": "True",
"TRANSCRIBE_DIRECTORY": "/path/to/transcribe_directory",
"WHISPER_MODEL": "base"
}
}
}
}
Alternatively, connect to a pre-deployed Streamable-HTTP instance by url:
{
"mcpServers": {
"audio-transcriber-mcp": {
"url": "http://localhost:8000/audio-transcriber-mcp/mcp"
}
}
}
Run a reviewed container image as a least-privilege stdio child (no listener or published port):
docker run -i --rm \
--read-only \
--cap-drop=ALL \
--security-opt=no-new-privileges \
--pids-limit=256 \
--tmpfs /tmp:rw,noexec,nosuid,nodev,size=64m \
-e TRANSPORT=stdio \
-e MCP_TOOL_MODE=intent \
-e AUDIO_PROCESSINGTOOL=True \
-e MEDIA_SIDECARTOOL=True \
-e MISCTOOL=True \
-e TRANSCRIBE_DIRECTORY=/path/to/transcribe_directory \
-e WHISPER_MODEL=base \
registry.example.invalid/audio-transcriber@sha256:<digest> audio-transcriber-mcp
For containerized network HTTP, supply an authenticated TLS ingress (or
direct server TLS), exact MCP_ALLOWED_HOSTS, and an exact trusted-proxy
CIDR policy through the operator-owned deployment profile. The generator
does not emit an unauthenticated non-loopback listener.
Auto-generated from the code-read env surface (MCP_TOOL_MODE + package vars) — do not edit.
Additional Deployment Options
audio-transcriber can run as a local stdio process or container, or behind a remote
network boundary. The
Deployment guide carries
the detailed transport contract.
- Local container — launch a reviewed immutable image as a least-privilege stdio child with no listener or published port.
- Remote URL — connect through an operator-supplied authenticated HTTPS
ingress. Keep its URL, outbound identity references, trust profile, and exact
MCP_ALLOWED_HOSTSinAgentConfig.
Agent
Configure transcription (optional)
export WHISPER_MODEL="base" export TRANSCRIBE_DIRECTORY="/path/to/transcribe_directory"
Connector-focused MCP server (includes the shared graph engine)
uv pip install "audio-transcriber[mcp]"
Everything (development)
uv pip install "audio-transcriber[all]" # or: python -m pip install "audio-transcriber[all]"
### Container images (`:mcp`)
One multi-stage `docker/Dockerfile` builds the MCP-only image (`--target mcp`):
| Image tag | Build target | Contents | Entrypoint |
|-----------|--------------|----------|------------|
| `example/audio-transcriber:mcp` | `--target mcp` | `audio-transcriber[mcp]` — **connector-focused**, includes `epistemic-graph[full]`; no model-orchestration stack | `audio-transcriber-mcp` |
```bash
docker build --target mcp -t example/audio-transcriber:mcp docker/ # connector-focused MCP server
agent (immutable agent digest) with a co-located :mcp sidecar.
Knowledge-graph database (epistemic-graph)
Agent Connector SDK core dependency (epistemic-graph[full]). The [mcp] extra keeps
deployments can use the bundled engine. For production or shared state, run
epistemic-graph as a dedicated database service and configure the runtime to use it.
Deployment recipes (single-node + Raft HA), connection configuration, and architecture
diagrams are documented in the
epistemic-graph deployment guide.

Deploy with agent-connector-sdk-deployment
Provision this package with the consolidated agent-connector-sdk-deployment
workflow. It selects an installed-package, editable-source, or immutable-container
path; records only runtime secret and TLS-profile references in AgentConfig; and
runs doctor, registration, policy, observability, and rollback gates. Ask your agent
to "deploy audio-transcriber with agent-connector-sdk-deployment".
| Install mode | Command |
|---|---|
| Installed package | uv tool install "audio-transcriber[mcp]", then run audio-transcriber-mcp |
| Immutable container | deploy registry.example.invalid/audio-transcriber@sha256:<digest> through the operator-selected orchestrator |
The repository embeds no deployment profile, credential value, certificate path, or
environment-specific endpoint. Supply those at runtime through AgentConfig and the
configured secret provider.
Governed capability contract
This package ships a compact canonical skill surface with specialist procedures
kept as referenced workflows. The current MCP tools, skill metadata,
connector_manifest.yml, ontology, mappings, shapes, fixtures, migrations,
tool-schema fingerprints, and certification metadata form one versioned
capability contract. Validate them together; do not rely on stale tool names or
historical per-task skill wrappers.
Runtime endpoints, credentials, certificate trust, tenant identity, retention, and observability policy are deployment inputs and are never packaged values. See Configuration, trust, and privacy before enabling a network transport, connector ingestion, Arbora delegation, or trace export.
