RecordHTML

RecordHTML MCP server

Connect RecordHTML to an AI assistant and ask it for videos. The hosted MCP server records web pages and HTML5 creatives (banners, ads, animations, landing pages) to MP4, WebM or GIF in a real browser. It uses the same recorder, limits and storage as the web app and the API.

https://mcp.recordhtml.com

Streamable HTTP, sign in with OAuth. There is nothing to install or run on your machine.

This repository holds the server's listing in the MCP Registry (com.recordhtml/mcp). The server itself is hosted and not open source. Full documentation: https://recordhtml.com/docs/mcp

Connect

Add a remote MCP server with the URL above. Your client opens a sign-in page: sign in or create an account, approve the access and go back to the client. It should then list five tools.

Claude Code: then type /mcp, choose recordhtml and sign in.

claude mcp add --transport http recordhtml https://mcp.recordhtml.com

Claude (claude.ai and Claude Desktop): Settings → Connectors → Add custom connector, with https://mcp.recordhtml.com as the URL, then Connect.

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "recordhtml": { "url": "https://mcp.recordhtml.com" }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "recordhtml": { "type": "http", "url": "https://mcp.recordhtml.com" }
  }
}

ChatGPT, Codex and other clients: see Set up your client.

With an API key

Headless agents, and clients that can set headers, can send an API key from the API settings page instead of signing in. Keys are refused from browser pages.

claude mcp add --transport http recordhtml https://mcp.recordhtml.com \
  --header "Authorization: Bearer $RECORDHTML_API_KEY"

Tools

Example prompt: Record https://example.com/banner/ at 300×600 for 15 seconds as an MP4.

Publishing (maintainers)

The server is published under the com.recordhtml namespace, proven by a DNS TXT record at the apex of recordhtml.com. You need mcp-publisher and OpenSSL 3 (macOS's built-in LibreSSL has no Ed25519).

One time: create a key and add its TXT record.

OPENSSL=/opt/homebrew/opt/openssl@3/bin/openssl
$OPENSSL genpkey -algorithm Ed25519 -out key.pem    # keep it secret; *.pem is git-ignored
echo "recordhtml.com. IN TXT \"v=MCPv1; k=ed25519; p=$($OPENSSL pkey -in key.pem -pubout -outform DER | tail -c 32 | base64)\""

Add that record at the apex (recordhtml.com, not a subdomain), next to the existing TXT records. When you rotate the key, remove the old record.

Each release:

mcp-publisher validate
mcp-publisher login dns --domain recordhtml.com \
  --private-key "$($OPENSSL pkey -in key.pem -noout -text | grep -A3 'priv:' | tail -n +2 | tr -d ' :\n')"
mcp-publisher publish
curl -s "https://registry.modelcontextprotocol.io/v0.1/servers?search=com.recordhtml/mcp"

version follows the server's own version (MCP_SERVER_VERSION in html-recorder-web). To republish with only metadata changes, use a prerelease such as 1.0.0-1. A version can't be published twice.
