Server details

Identifier: io.usefulapi/viralsweep
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Oct 30, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to usefulapi.io, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted read-only MCP access to ViralSweep brands, promotions, entrant summaries and existing winners, with usage metering and subscription tools.

What you can do: List brands and their promotions, optionally active or archived
Read promotion entries with entrant emails and entry/referral counts, searchable by email address
Read a promotion's existing winners and prize titles, filterable by Unix timestamps
Check monthly tool-call usage, request a missing feature, and start or cancel a paid plan
When to use it: Useful when you want an assistant to look up ViralSweep giveaway data — which brands and promotions exist, who entered, and who already won — without opening the dashboard. It is read-only, so it suits reporting and quick lookups rather than running or editing campaigns.
Requirements: A remote MCP endpoint added by URL only; no API key or Authorization header. Sign-in happens through OAuth on a hosted page that asks for your own ViralSweep credentials. A free tier allows 50 tool calls per month; paid plans raise the limit.

Before you install

The hosted sign-in page collects your ViralSweep account credentials, so trust in the third-party host matters. Entrant data includes email addresses, which are sent to the assistant and the hosting service. Subscription tools can start a paid plan through a Stripe Checkout link or cancel it, with no refund for the current period; confirm before running them.

Installation

In SourceWeft

Open ViralSweep MCP by usefulapi in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fviralsweep/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
