Overview

Description from the maker (original English)

Read WaiverFile waivers, events, forms and SMS opt-ins; create and update events, invite managers.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • Can do 17 things (tools) waiverfile_get_site, waiverfile_list_waiver_forms, waiverfile_list_events, waiverfile_list_upcoming_events …
  • The registry lists no key to fill in.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

    List upcoming waiver events between two dates (UTC), for example the next 7 days. GET /GetUpcomingEvents.

  • waiverfile_find_waivers_by_reference

    Find waivers by the reference ids an outside booking or reservation system attached to them (referenceID1, 2, 3). Give at least one of reference_id_1/2/3, or reference_id_any to match all three fields. GET /GetWaiversByReferenceID.

  • waiverfile_list_waivers

    A page of the waivers signed in a date range. Set lite for only the collected form data (smaller). For a flat export with custom form columns use waiverfile_export_waiver_data; for totals use waiverfile_count_waivers. Personal data of signers. GET /GetAllWaiversByDateRange or /Ge

  • waiverfile_export_waiver_data

    A page of flat waiver rows for a date range (the data behind the WaiverFile export): standard fields, optionally every custom form field as a column, and participants either as one comma-separated column or one row each. Personal data of signers. GET /GetWaiverData.

  • waiverfile_count_waivers

    How many waivers a date range holds: record_count (GetWaiverDataCount, the rows waiverfile_export_waiver_data pages through) and waiver_count (GetAllWaiversByDateRangePageCount, which WaiverFile documents as the number of waivers in the range, used to work out the pages of waiver

  • waiverfile_list_sms_subscribers

    SMS marketing subscribers (phone numbers) that opted in during a date range, or with opted_out set the ones that opted out. Dates are UTC. Personal data. GET /GetSubscribersByDate or /GetOptedOutSubscribersByOptOutDate.

  • waiverfile_update_event

    Update an existing event. WaiverFile replaces the whole event, so name, start, end and all_day are required and anything left out is reset: category_id empty = no category, waiver_form_ids empty = ALL active forms are attached. Read the event first (waiverfile_list_events) and se

  • waiverfile_invite_event_managers

    SENDS EMAIL: invites people (by email address) to manage one event; they can log in to WaiverFile and see its signers and participants, with the fields set in the account settings. WaiverFile emails each address, with your optional message in the body (skip_email_if_account_exist

  • waiverfile_create_event_category

    Create an event category (a label to group events). Not idempotent: calling twice with the same name creates two categories. POST /InsertEventCategory.

Common questions

Is WaiverFile MCP by usefulapi safe?

It passed 3 of 3 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 –, and the latest version (1.14.4) 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 in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://waiverfile.usefulapi.io/mcp.
