Zvid

@zvid/mcp

Official Zvid agent and MCP server. Creator follows a quality-first workflow: plan the brief, adapt designed examples or library assets, validate exact project JSON, save a reviewable draft, then render only after approval. Automation and Developer add trusted direct operations.

Authentication

There are exactly two ways to authenticate. Every setup below uses one of them:

Method 1 — OAuth sign-in. Add https://mcp.zvid.io/mcp to your MCP client and sign in when prompted. The endpoint publishes OAuth discovery metadata, uses authorization code + PKCE with the single scope zvid:mcp, and issues short-lived access tokens with rotating refresh tokens (revocable per RFC 7009). This is what the client-specific instructions below use.

Method 2 — API key. Create a key at app.zvid.io/api-keys, then either:

• Hosted: send it in the X-Api-Key header on https://mcp.zvid.io/mcp — for programmatic clients that cannot run an OAuth flow, or legacy access.
• Local stdio / self-hosted: pass it via ZVID_API_KEY / --api-key as shown in Local stdio / self-hosted setup. The stdio transport is API-key only, because MCP OAuth is defined for HTTP transports.

Hosted setup (recommended)

The hosted endpoint is https://mcp.zvid.io/mcp. It accepts both authentication methods: OAuth sign-in (method 1 — used by the client instructions below) and an API key in the X-Api-Key header (method 2).

Claude Code

claude mcp add --transport http zvid https://mcp.zvid.io/mcp

claude mcp login zvid

You can also open /mcp inside Claude Code and authenticate there.

OpenAI Codex

Register the server, then authenticate from MCP settings or the command line:

codex mcp add zvid --url https://mcp.zvid.io/mcp

codex mcp login zvid

The dashboard stores the default tool profile and maximum credits per render for MCP clients. A client may connect with concrete values in the endpoint, for example https://mcp.zvid.io/mcp?profile=creator&maxRenderCredits=60; this is connection configuration and cannot be changed by the model during a conversation. The default per-render credit limit is 120, and the dashboard limit, when set, is a hard ceiling: the effective limit is the lower of the dashboard value and the value requested in the endpoint.

The official n8n workflow copies both dashboard defaults into its workflow JSON when downloaded. Each workflow can then choose another concrete profile and credit ceiling locally without updating the dashboard or any other workflow.

Local stdio / self-hosted setup

The npm/stdio entry point uses an API key (authentication method 2). Configuration resolution is CLI flags, then environment, then ~/.zvid-mcp.json:

npx -y @zvid/mcp --api-key zvid_your_key_here --api-url http://localhost:4000

For a self-hosted OAuth deployment, keep the resource and issuer identical on both services:

The orchestrator also accepts OAUTH_ACCESS_TOKEN_TTL_SECONDS and OAUTH_REFRESH_TOKEN_TTL_SECONDS; their defaults are one hour and 30 days.

From a checkout:

cd mcp && npm install && npm run build

claude mcp add zvid --env ZVID_API_KEY=zvid_your_key_here -- node /absolute/path/to/mcp/dist/index.js

Default Creator workflow

The default creator profile is the former Advanced authoring surface. It exposes planning, designed examples, creative-library search, stock media, schema/docs, repair, validation, projects and templates alongside approval-aware draft tools.

Creator deliberately rejects create_media and revise_media calls that omit the complete project payload. This prevents a weak model from improvising a poor layout from a brief. The agent must plan, adapt or assemble an exact payload, validate it remotely, fix every error and layout warning, and only then save the draft. create_media remains non-spending; render_media still requires the user-approved signed quote.

When the user asks for a reusable template rather than a one-off video or image, create_media_template saves a parameterized project — a top-level variables object of safe defaults referenced via {{name}} placeholders — as a persistent tpl_… template. It returns the declared variables, a credit estimate for rendering the untouched defaults, and an editor deep link (https://editor.zvid.io/?template= ). create_media_from_template then instantiates the template with new variable values as an approval-gated draft with a signed quote. Neither call spends credits. In the creator profile create_media_template requires the complete parameterized payload, mirroring create_media.

Rendering is deliberately separate from drafting. Quote tokens are HMAC-signed, expire after 15 minutes, bind the draft ID, project version, canonical payload hash, media type and estimated credits, and are revalidated immediately before submission. An idempotency UUID prevents retry duplication.

Capability profiles

Update and delete tools remain disabled in every profile. Stored webhook secrets are redacted by get_webhook; only create_webhook returns a new secret. MCP bulk calls normally allow at most 25 items, subject to account limits. The direct REST API's 500-item hard cap does not raise this tool ceiling; split work into appropriately sized batches.

The server also publishes four user-invoked workflow prompts (product promo, social reel, thumbnail and square post) and safe MCP resources at zvid://authoring/guidelines and zvid://account/summary.

Creator, Automation and Developer tools
