Connect an MCP client

Paste this URL into any MCP client that speaks Streamable HTTP:

https://mcp.prezzly.ai

Prezzly authenticates with Authorization: Bearer <token>. Prefer OAuth when the client supports it. If it asks for a key, generate one under Connections.

Note: After you connect, install the Prezzly skill so the agent uploads files locally (uploadUrl + curl) instead of pasting image contents into tool calls.

Cursor

Add this to .cursor/mcp.json in the project (or your user MCP config). The url field is enough:

{
  "mcpServers": {
    "prezzly": {
      "url": "https://mcp.prezzly.ai"
    }
  }
}

Reload MCP in Cursor Settings. Cursor starts OAuth and asks you to sign in to Prezzly. Then tell the agent to upload the project folder. See Publish and update a deck.

Claude.ai

Settings → Connectors → Add custom connector. Paste https://mcp.prezzly.ai. Claude starts OAuth and asks you to sign in to Prezzly.

Ask Claude to build or upload the deck. In the browser it has no disk, so it should call create_presentation with a self-contained index.html in files.

Claude Code

claude mcp add --transport http prezzly https://mcp.prezzly.ai

Claude Code starts OAuth when the client supports it. Otherwise paste a Bearer key from Connections.

Claude Desktop

Add a custom connector with https://mcp.prezzly.ai, or put the same JSON as Cursor into the Desktop MCP config. Prefer OAuth. A Bearer key from Connections also works.

VS Code (Copilot)

In .vscode/mcp.json or your user MCP settings:

{
  "servers": {
    "prezzly": {
      "url": "https://mcp.prezzly.ai",
      "type": "http"
    }
  }
}

Field names vary by VS Code build. If the editor asks for a header, set Authorization to Bearer <key> from Connections.

Windsurf, Cline, and Zed

Any client that accepts a Streamable HTTP MCP URL can use https://mcp.prezzly.ai. Use OAuth when the client starts it. Otherwise add:

Authorization: Bearer <your-prezzly-mcp-key>

ChatGPT and other hosts

If the host lets you add a custom MCP or connector URL, paste https://mcp.prezzly.ai. Chat clients without a disk should send HTML in files, not a zip. See Publish and update a deck.

OAuth vs API key

Method	When to use
OAuth	Cursor, Claude.ai, and any client that opens a Prezzly sign-in window
Bearer API key	Desktop or CLI clients that only accept a token

Create and revoke keys on Connections. A 401 with a create_upload_link hint means the upload token expired, not that you lost the connection. Mint a new upload URL and continue.

If tools look stale (no create_upload_link), reload the MCP server in the client. Do not fall back to pasting HTML into add_revision.
