Synthesia MCP

Connect Synthesia to the AI tools your team already works in.

With Synthesia MCP, you can turn a script or an idea into a Synthesia video draft, or create and edit a Syren video, from inside Claude or ChatGPT, without copy-pasting between apps.

Quick start

ChatGPT: install Synthesia from the ChatGPT marketplace listing
Claude and other MCP clients: point your client at the server URL: https://mcp.synthesia.io/mcp

Synthesia MCP is in public beta

Synthesia MCP is now open to everyone, but it’s still under active development, so you may run into bugs or rough edges. Found something that’s not working right? Let us know using this form.

What is Synthesia MCP?

Synthesia MCP is our hosted server built on the Model Context Protocol (MCP), an open standard that lets AI assistants securely call out to external tools. It gives MCP-compatible clients a curated set of tools for creating, generating, and finding Synthesia videos, grounded in your workspace’s brand kit, templates, and avatars.

Because it’s a standard MCP server, it works alongside the other connectors you already use in a conversation. Pull source material from Slack, Notion, or Drive and turn it into a video draft in the same chat.

What can you do with it?

Turn an idea or script into a video draft: describe a video, or paste an existing script, and the assistant creates a draft in Synthesia
Get a draft that already looks on-brand: drafts are built from your workspace’s templates and avatars, so the first version already reflects your setup rather than a blank template
🆕 Pick a Style if you don’t have a brand kit: choose one of Synthesia’s curated Styles, or a template, in the setup widget
Pick your setup in-chat: an interactive widget lets you choose workspace, template, brand kit, and avatar before generation starts, then shows the draft as soon as it’s ready
Generate the final video without leaving the chat: once a draft looks right, ask Claude or ChatGPT to generate it and follow render progress in the same conversation—no need to switch to the editor first
Create and edit Syren videos by chatting: include “use Syren” in your prompt, watch the video in the Syren player in the chat, and refine it by describing the changes you want
Finish or refine in the editor: every Studio draft (and every video generated from one) also opens directly in the Synthesia editor if you want to make edits
Search your video library from the chat: look up existing videos, list and filter what you have access to, and pull metadata for a specific video
Chain it with other tools: combine it with any other MCP connector in the same conversation (for example: “summarize this doc from Notion and turn it into a video”)

Brand kit selection is available on Enterprise plans.

On other plans, you can pick one of Synthesia’s curated Styles or templates.

How it works

Synthesia MCP exposes a small, purpose-built set of tools rather than the full Synthesia API surface:

Tool group	What it does
Identity	Confirms who you’re signed in as and which workspace you’re acting in
Brand context	Reads available brand kits, templates, and avatars for the draft setup widget
Create draft	Generates a video draft from a script or a prompt
Draft status	Reports progress while a draft is being created
Generate video	Starts final video generation from a ready draft
Generation status	Reports render progress for a video that’s generating
Video search / list / get	Finds existing videos and returns metadata
Delete draft	Removes a draft you no longer need
Syren create / edit	Creates a Syren video from a brief and applies changes you describe in chat
Syren status / export	Reports progress, and exports the full-quality video file

Note:

Creating a draft isn’t instantaneous. Expect a short wait, typically 30-90 seconds, before it’s ready to open in the editor. Generating the final video takes longer than creating a draft—about as long as generating that same video directly in Synthesia would.

If a tool doesn’t show up yet:

When we add or change tools, most MCP clients still show the old list until you refresh. In Claude, restart the desktop or web app. In ChatGPT, ask your workspace admin to refresh the plugin from Settings → Plugins → Synthesia → Actions → Refresh.

Prerequisites

A Synthesia account on a Starter or Pro plan, or an enterprise Synthesia account in a workspace with login via WorkOS—if you’re on an enterprise workspace, accounts still on the legacy Cognito sign-in need to migrate before they can connect:
- If you don’t have SSO enabled for your organization (i.e. if you log in with your email and password), you should be fine
- If you log in via SSO and you’re not sure which your organization uses for Synthesia, check with your IT admin
A Claude or ChatGPT workspace where an admin has already enabled the Synthesia connector—whether you need this depends on your Claude/ChatGPT plan, not your Synthesia plan. See Connect as a personal user or as a workspace admin and Connect as an enterprise workspace member below.

Connect as a personal user or as a workspace admin

Follow these steps if you’re connecting Synthesia MCP to your own personal Claude or ChatGPT account, or if you’re a workspace/organization admin setting it up for your team. If you’re joining an enterprise workspace where an admin has already added Synthesia, skip to Connect as an enterprise workspace member instead.

The server is public at https://mcp.synthesia.io/mcp, so it should be reachable from your AI provider’s cloud without any firewall or allowlisting changes on your end.

Claude

Personal accounts (not part of a company workspace):

Go to Customize → Connectors
Select the + button next to Connectors
Select Add custom connector
Enter a name and the server URL https://mcp.synthesia.io/mcp
Leave the OAuth client ID and secret fields empty—Synthesia authenticates via WorkOS, so no client credentials are needed
Select Add, then follow the connection prompts to sign in

Workspace or organization admins (Team/Enterprise):

Go to Organization settings → Connectors
Select Add, hover over Custom, then choose Web
Enter the server URL https://mcp.synthesia.io/mcp
Leave the OAuth client ID and secret fields empty
Select Add

Workspace members then connect individually from Customize → Connectors, by finding Synthesia (labeled Custom) and selecting Connect.

See Anthropic’s guide to custom connectors using remote MCP for more on this flow.

Note:

If we update the server’s tool list or descriptions, refresh the connector from Settings → Connectors → Synthesia → Refresh. On Claude’s Business plan, connectors can’t be updated after publishing, so you’ll need to recreate and republish to pick up changes.

ChatGPT

Synthesia is now listed in the ChatGPT marketplace, so Developer Mode is no longer required.

Open ChatGPT and go to Settings → Apps (or Plugins, depending on your account)
Find Synthesia and select Install plugin (or Connect)
Sign in to your Synthesia account and review the requested permissions
Confirm you can tag Synthesia in a message box, then try a prompt using it

Note:

On ChatGPT Business, Enterprise, or Edu workspaces, admins control whether Synthesia is enabled by default. If Synthesia shows Disabled by admin, ask your workspace admin to enable it from Workspace settings → Apps.

Other MCP clients

Point any MCP-compatible client at the server URL:

https://mcp.synthesia.io/mcp

Note:

Claude and ChatGPT are the only clients we currently test against. If you connect from another client and run into issues, let us know via the feedback form.

Connect as an enterprise workspace member

These steps are for members of an enterprise workspace where an admin has already enabled Synthesia MCP as an org-wide connector.

Claude

Open Claude Desktop or the Claude web app
Go to Settings → Connectors
Find Synthesia in the list of connectors and select Connect
A Synthesia window will open, where you can approve the permissions and sign in (your session is cached, so you won’t be asked to approve every time)
Confirm the Synthesia connector appears under the connectors icon in the message box, then try a prompt using it

ChatGPT

Open ChatGPT and go to Settings → Apps (or Plugins)
Find Synthesia and select Connect
Sign in to your Synthesia account and review the requested permissions
Confirm you can tag Synthesia in a message box, then try a prompt using it

If Synthesia doesn’t appear or shows Disabled by admin, your workspace admin needs to enable it from Workspace settings → Apps first.

Create and edit videos with Syren

You can create and edit Syren videos from Claude or ChatGPT. The Syren player appears in the chat, and you refine the video by describing the changes you want.

Syren videos created with Synthesia MCP consume credits.

Create a Syren video

In Claude, go to Settings → Connectors → Synthesia, and confirm the Syren tools aren’t set to Blocked.
Start a new chat.
Turn Synthesia on. In Claude, select the + menu and switch on Synthesia. In ChatGPT, tag Synthesia in the message box.
Ask for a video and include “use Syren” in your prompt. For example: “Turn this Notion page into a 60-second explainer with Syren.”

The Syren player appears in the chat with your video.

If your prompt doesn’t include “use Syren”, the assistant may create a video draft instead.

Edit and export a Syren video

Describe the change you want in the same chat.
Review the updated video in the Syren player.
Repeat until you’re happy with the video.
Ask the assistant to export the full-quality video file.

Permissions and scope

Provider	Authentication	Scope
Claude / ChatGPT	OAuth via WorkOS, per user	Single-workspace—tool calls only ever touch the Synthesia workspace you’re signed into

Note:

Video search and listing tools are permission-scoped: you only see videos you already have access to in Studio.

Rate limits

To keep a runaway agent or scripted loop from generating an unbounded number of videos, Synthesia MCP applies per-user limits on how many drafts and video generations you can kick off per hour. Normal use shouldn’t come close to these limits. If you do hit one, you’ll get a clear message asking you to try again later, and nothing will be created in the meantime.

Things to know

Studio drafts can’t be edited from the connector: you can’t change a draft’s scenes, narration, layout, or avatar from Claude or ChatGPT. Open the draft in the Synthesia editor to make those changes. When you generate the video, it uses the draft’s current state, so your editor changes carry through.
Syren videos are edited in chat: describe the change you want in the chat where you created the video, and the assistant updates it in the Syren player. Each change is saved as a new version, so you can ask to undo a change or restore an earlier version.
Syren videos can’t be opened in the Synthesia editor.
Draft quality is still maturing: script-to-draft generation is an early integration with the Synthesia Assistant, so drafts may be rougher than what you’d get from the Assistant inside the platform itself
Search is keyword-based: search is not semantic and doesn’t yet support filtering by date range
ChatGPT marketplace listing available; Claude still connector-only: Synthesia MCP is listed in the ChatGPT marketplace. It isn’t listed in Claude’s directory yet—connect there using the custom connector steps above
Draft creation is not instantaneous: a draft typically takes 30-90 seconds to generate
Only tested with Claude and ChatGPT: other MCP clients may work but aren’t officially supported

FAQ

Which AI tools does it work with?

Claude and ChatGPT today. It’s a standard MCP server, so in principle any MCP-compatible client can connect via the server URL, but we’ve only tested Claude and ChatGPT—treat other clients as experimental.

Why can’t I sign in?

If you log into Synthesia via SSO, the most common cause is still being on the legacy Cognito sign-in rather than WorkOS.

SSO itself isn’t required, so if you log in with an email and password, that means you authenticate via WorkOS, so it should work fine.

The other common cause is not having a qualifying Synthesia plan (Starter, Pro, or Enterprise). Check with your Synthesia account team if you’re unsure.

Does it edit my videos?

It depends on the video type. You can edit a Syren video by describing the change you want in the chat. You can’t edit a classic draft from the connector. Open the draft in the Synthesia editor, and your changes carry through when you generate the video.

Does this consume credits in Synthesia?

For Studio drafts, creating a draft doesn’t consume credits. Generating the final video does, the same way it would if you started that video directly in Synthesia—credits are based on the video’s duration. If you’re on Enterprise, you have unlimited Studio video generation, so no credits are consumed either way. Syren videos created through the connector use credits, just as they do in Synthesia.

Will the draft match our branding?

On Enterprise plans, yes—drafts are built from your workspace’s brand kit, templates, and avatars, so the first version already looks on-brand. On other plans, drafts are built from a Style or template you choose in the setup widget instead. You’ll typically still make some adjustments in the editor either way.

Does generating a video through the connector cost extra?

No. Generating a video via Synthesia MCP works the same way as generating it directly in Synthesia.

Is it on the Claude or ChatGPT marketplace?

Yes, on ChatGPT. It’s not yet listed in Claude’s directory—connect there using the server URL and the custom connector steps above.
