What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

  • webinarnet_list_webinars

    List the webinars in the account, one page at a time, with title, language, screen-sharing and green-room settings, and the latest schedule. Good first call to find a webinar id. webinar.net Open API: GET /webinars.

  • webinarnet_get_webinar

    Get one webinar by id: title, language, source, URLs and the latest schedule. webinar.net Open API: GET /webinars/{webinarId}.

  • webinarnet_get_webinar_summary

    Get the summary of one webinar: title, folders, start date, duration, and the registrant, live attendee, on-demand attendee and no-show counts. webinar.net Open API: GET /webinars/{webinarId}/summary.

  • webinarnet_list_schedules

    List the schedules (session dates and times) of one webinar, with their type, status and time zone. webinar.net Open API: GET /webinars/{webinarId}/schedules.

  • webinarnet_get_schedule

    Get one schedule of a webinar: start, end, time zone and status. webinar.net Open API: GET /webinars/{webinarId}/schedules/{scheduleId}.

  • webinarnet_get_registration_form_fields

    List the registration form fields of one webinar: key, label, type, order and whether each field is required. Call this before webinarnet_create_registrant to get the right keys. webinar.net Open API: GET /webinars/{webinarId}/registration-form/fields.

  • webinarnet_list_registrants

    List the registrants of one webinar, one page at a time, with their registration fields, source and date. Personal data: only read what the task needs. webinar.net Open API: GET /webinars/{webinarId}/registrants.

  • webinarnet_get_registrant

  • webinarnet_list_attendees

    List the attendees of one webinar, one page at a time: live and on-demand attendance flags, join dates and watch durations, and optionally each attendee's activities. Personal data: only read what the task needs. webinar.net Open API: GET /webinars/{webinarId}/attendees.

  • webinarnet_create_registrant

    Add a registrant to a webinar. This creates a real registration on the webinar. Get the field keys with webinarnet_get_registration_form_fields first. Not idempotent: a second call creates a second registrant. webinar.net Open API: POST /webinars/{webinarId}/registrants.

  • webinarnet_update_registrant

    Change the registration answers of one registrant. Send the fields to change, with their keys from webinarnet_get_registration_form_fields. Repeating the same call gives the same result. webinar.net Open API: PUT /webinars/{webinarId}/registrants/{registrantId}.

Common questions

Is webinar.net 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 (1.4.3) reached the registry today.

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 Business and above.

What can I use instead?

webinar.net MCP by usefulapi

Use your webinar.net account from Claude, Cursor, or any MCP client. Read webinars, schedules, registrants and attendees, and register or update people. Hosted, no local install: connect with your own credentials.

Live endpoint: https://webinar-net.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://webinar-net.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http webinar-net https://webinar-net.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": { "webinar-net": { "url": "https://webinar-net.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 webinar.net credentials.

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

On first connect you provide an API Key and an API Secret (webinar.net → Account Settings → Open API → API Credentials). The account owner creates them. The server validates it and stores it per user. No keys go in config files.
