Common questions

Is BigMarker MCP by usefulapi safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.6.2) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

BigMarker MCP by usefulapi

Use your BigMarker account from Claude, Cursor, or any MCP client. Read conferences, channels, registrants, attendees, no-shows, presenters and recordings, and register or cancel people. Hosted, no local install: connect with your own credentials.

Live endpoint: https://bigmarker.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://bigmarker.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http bigmarker https://bigmarker.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "bigmarker": { "url": "https://bigmarker.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your BigMarker credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/bigmarker/

On first connect you provide a BigMarker API key (BigMarker → Settings → API keys). If the page shows no key, ask BigMarker support to enable API access. The server validates it and stores it per user. No keys go in config files.

Pro+ (per user)$39/mo or $390/yr (2 months free)100,000 tool calls / month

Each paid plan covers this server only. Ask your AI to run bigmarker_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with bigmarker_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with bigmarker_upgrade before then undoes the cancel. Or write to support@usefulapi.io.
