## Description
Create amazing video experiences with the Qencode API, straight from your AI assistant.

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "qencode": {
    "command": "npx",
    "args": ["-y","qencode"]
  }
}
```

## Documentation & README

# qencode-mcp

Model Context Protocol (MCP) server for the [Qencode Transcoding API](https://docs.qencode.com/api-reference/transcoding).

Connect any MCP-compatible AI client — Claude, Cursor, ChatGPT, Grok, Gemini — to your Qencode account and let it submit, monitor, and reason about transcoding jobs on your behalf.


## Quick example

Once your client is connected (see [Connect a client](#connect-a-client)), ask your agent in plain English:

> Transcode `https://example.com/input.mp4` as an HLS ladder at 1080/720/540/360. Put it in my R2 bucket `videos/demo/`.

The agent picks the `hls_abr` recipe, fills in the per-rendition encoding params, submits via `start_encode2_raw`, and polls until the job is done.

## Prerequisites

- A **Qencode portal account** with at least one project — sign in at the portal for your environment: <https://portal.qencode.com> (production) or <https://portal-qa.qencode.com> (QA). You select the project during the OAuth consent step.
- An **MCP-compatible client** (Claude, Cursor, ChatGPT, Grok, Gemini, or any custom client).

There are no API keys to copy into client config — authentication is browser-based OAuth.

## How it works

The connector uses standard OAuth 2.1 — no API keys in client config. On first use, your client opens a browser, you sign in to your Qencode portal account, pick a project, and approve the requested scopes. The client stores the token; subsequent calls are silent until the token expires.

**Scopes the client should request at authorize time** (published via Protected Resource Metadata):

| Scope | Purpose |
| ----- | ------- |
| `openid` | OIDC identity |
| `profile` | Display name |
| `email` | Account email |
| `offline_access` | Refresh token |
| `transcoding:read` | `get_job_status`, `wait_for_job`, docs tools |
| `transcoding:write` | `transcode_video`, `start_encode2_raw` |

The RS enforces `transcoding:read` and `transcoding:write` on access tokens at the transport layer.

Your Qencode API keys never leave the portal. The MCP server derives a short-lived session token per request via an internal portal endpoint.

## Environments

The same connector is deployed in two environments. Each has its own domains, accounts, projects, and credentials — sign in to the portal that matches the endpoint you connect to.

| Role | Production | QA (testing) |
| --- | --- | --- |
| MCP endpoint (connect here) | `https://mcp.qencode.com/mcp` | `https://mcp-qa.qencode.com/mcp` |
| Portal (sign in / projects) | `https://portal.qencode.com` | `https://portal-qa.qencode.com` |
| Authorization server | `https://auth.qencode.com` | `https://auth-qa.qencode.com` |
| Qencode API | `https://api.qencode.com` | `https://api-qa.qencode.com` |

The instructions below use the **production** endpoint. To test against QA, swap in the QA URL and sign in at the QA portal.

## Connect a client

**Endpoint:** `https://mcp.qencode.com/mcp` — same for every client below. Sign in to your Qencode account when the browser opens and approve access.

> **QA (internal testing):** use `https://mcp-qa.qencode.com/mcp` and sign in at the QA portal instead.

| Client | Where to add it | MCP URL / config |
| --- | --- | --- |
| **Claude** (chat) | Message box → **+** → Connectors → Add connector | `https://mcp.qencode.com/mcp` |
| **Claude Code** | Terminal | `claude mcp add --transport http qencode https://mcp.qencode.com/mcp` |
| **ChatGPT** | Apps → search **Qencode** → Connect; or Developer Mode → Build app | Connector URL: `https://mcp.qencode.com/mcp` |
| **Gemini** | `~/.gemini/settings.json` → `mcpServers` | `"httpUrl": "https://mcp.qencode.com/mcp"` — then `/mcp auth qencode` in the CLI |
| **Cursor** | Settings → Tools & MCP → New MCP Server (or `~/.cursor/mcp.json`) | `"url": "https://mcp.qencode.com/mcp"` — restart Cursor after saving |

**Cursor** (`mcp.json`):

```json
{
  "mcpServers": {
    "qencode": { "url": "https://mcp.qencode.com/mcp" }
  }
}
```

**Gemini** (`settings.json`):

```json
{
  "mcpServers": {
    "qencode": {
      "httpUrl": "https://mcp.qencode.com/mcp",
      "timeout": 30000,
      "trust": false
    }
  }
}
```

Tip: sign in to [portal.qencode.com](https://portal.qencode.com) in your browser before connecting — OAuth goes smoother.

## What the connector exposes

### Tools

**Transcoding & jobs**

| Tool | Description |
| ---- | ----------- |
| `transcode_video` | Submit a job from a source URL to one or more outputs. Convenience wrapper — auto-injects `encoder_version: 2` (or `1` for VMAF) when omitted. |
| `start_encode2_raw` | Escape hatch — submit a job with the full `query` JSON exactly as the [Qencode API](https://docs.qencode.com/api-reference/transcoding/#start_encode2___query__attributes--format__attributes) expects. |
| `get_job_status` | One-shot status snapshot by `task_token`. |
| `get_job_status_detailed` | Full, authoritative job status, including per-rendition progress and output details. |
| `wait_for_job` | Poll until terminal state, timeout, or internal poll cap. Do not call in parallel with other tools in the same client batch. |
| `search_qencode_docs` | Search the built-in knowledge base of recipes and reference docs. |
| `fetch_qencode_doc` | Fetch the full content of a knowledge-base resource by `qencode://` URI (tool-based counterpart to `resources/read`). |

**Media Storage**

Bucket management and ingest for Qencode Media Storage. These ride the same OAuth grant as the transcoding tools — no extra scope and no re-consent.

| Tool | Description |
| ---- | ----------- |
| `list_buckets` | List the Media Storage buckets available to the account. |
| `create_bucket` | Create a new bucket. Called only on an explicit request — not to satisfy a missing `destination`. |
| `list_objects` | Browse the contents of a bucket. |
| `get_download_url` | Return a time-limited download URL for an existing object. |
| `download_url_to_bucket` | Server-side copy of a public URL into a bucket (ingest, no transcoding). |

### Resources

The server ships a knowledge base of recipes and reference docs, exposed as MCP resources so the agent can fetch only what it needs. Notable URIs:

- `qencode://docs/best-practices` — composition defaults the agent applies automatically
- `qencode://docs/storage` — destination compatibility matrix (Qencode S3, R2, AWS S3, Azure, B2, FTP/SFTP)
- `qencode://docs/error-codes` — error code → cause → fix
- `qencode://docs/gotchas` — non-obvious API quirks
- `qencode://schema/digest` — full attribute reference for `start_encode2`
- `qencode://recipe/<slug>` — one per feature flow: `hls_abr`, `mp4_ladder`, `audio_outputs`, `thumbnails`, `speech_to_text`, `subtitles`, `stitching`, `drm_widevine_ezdrm`, `drm_fairplay_ezdrm`, `drm_playready_ezdrm`, `drm_aes128`, `drm_buydrm`, `drm_expressplay`, `codec_av1`, `per_title_encoding`, `incremental_abr`, `refresh_abr_playlist`, `callbacks`, `reliability`, `video_metadata`

Use `search_qencode_docs` to discover the right recipe URI for a goal.

### Prompts (slash commands)

In clients that surface MCP prompts, **21** one-shot templates are available. Each tells the agent to read the matching `qencode://recipe/...` resource and submit via `start_encode2_raw`.

**ABR / packaging:** `encode_hls_abr`, `encode_dash_abr`, `encode_mp4_ladder`, `encode_incremental_rung`, `encode_refreshing_playlist`

**Codecs / quality:** `encode_av1`, `tune_per_title`

**Audio / images / text:** `extract_audio`, `generate_thumbnails`, `transcribe`, `add_subtitles`

**Probe / stitch:** `get_video_metadata`, `stitch_videos`

**Production hooks:** `enable_callbacks`, `enable_reliability`

**DRM:** `encode_aes128_hls`, `encode_widevine_ezdrm`, `encode_playready_ezdrm`, `encode_fairplay_ezdrm`, `encode_drm_buydrm`, `encode_drm_expressplay`

### Source URL rules

`transcode_video` and `start_encode2_raw` accept `source` values with schemes `https://`, `http://`, `s3://`, or `tus:`. FTP/SFTP and private/metadata URLs are rejected at the tool boundary (SSRF defence). See `docs/security/THREAT_MODEL.md` for limitations.

## Security

Authentication is OAuth 2.1 only — there is no static-API-key mode. Your Qencode API keys never leave the portal; the server derives a fresh, short-lived session token per request via an internal portal endpoint. Source URLs are validated at the tool boundary (SSRF defence — see [Source URL rules](#source-url-rules)).

Full threat model and adversarial test coverage: [`docs/security/THREAT_MODEL.md`](docs/security/THREAT_MODEL.md).

## Development

```bash
uv venv && uv pip install -e ".[dev]"
NO_NETWORK=1 pytest -q              # offline L1 + L2 + L5 (~540 tests)
pytest -m protocol                # MCP wire conformance only
pytest -m unit                    # per-tool logic (FakeQencode)
pytest -m security                # OWASP MCP Top 10 adversarial suite
```

Protocol tests run fully offline (mocked Authorization Server, portal, and Qencode API). **CI** is the Jenkins job `mcp_automated_tests` (`Jenkinsfile.manual`): manual checkboxes for any layer, nightly L3 cron, weekly L4 cron.

### Supported MCP protocol versions

Clients negotiate a version at `initialize`. This server targets **[MCP 2025-11-25](https://modelcontextprotocol.io/specification/2025-11-25)** as the primary version. CI also runs conformance tests against **2025-06-18** because JSON-RPC batching behavior differs between earlier revisions. We do not claim support for **2025-03-26** or older wire semantics beyond what the underlying SDK negotiates.

| Version     | Support        | Notes                                      |
| ----------- | -------------- | ------------------------------------------ |
| 2025-11-25  | Primary        | Streamable HTTP, resumable SSE where used  |
| 2025-06-18  | CI matrix      | Regression guard for mid-2025 clients      |
| 2025-03-26  | Not targeted   | Batching semantics differ from 2025-06-18  |

## Versioning policy

The connector follows [SemVer](https://semver.org/) applied to the **MCP surface** — tools, prompts, resources, OAuth scopes, and supported protocol versions. Qencode HTTP API changes are out of scope (they are the API's own concern, not the connector's).

- **MAJOR** — a breaking surface change: a tool/prompt/resource is removed or renamed, a previously optional argument becomes required, an OAuth scope is added or tightened in a way that forces re-consent, or a supported MCP protocol version is dropped.
- **MINOR** — a backward-compatible addition: a new tool/prompt/resource, a new optional argument, or a newly supported protocol version.
- **PATCH** — no change to the surface shape: tool/prompt description rewordings, knowledge-base/doc updates, and bug fixes.

Surface changes are guarded by snapshot tests under [`tests/protocol/`](tests/protocol). When you change the surface, regenerate the snapshots (`python scripts/regen_tools_snapshot.py`) and bump the version in the **same** PR: `pyproject.toml`, `src/qencode_mcp/__init__.py`, `server.json`, and a new `CHANGELOG.md` entry must all agree.
