upvoteclub/upvote-club-mcp-mcpb

This repository packages the Upvote.club MCP server as a Claude Desktop extension, using the .mcpb bundle format. Instead of manually cloning a repository and editing a config file, you install it with a single double click and Claude Desktop's Settings menu, which then lets you ask Claude to promote a link using Upvote.club's service directly from a conversation. Upvote.club maintains several related packages for connecting to their API in different ways. A core package holds the shared server library, a local package runs over stdio for tools like Cursor and Claude Code, this MCPB package is the single click Claude Desktop install, a remote package works as a Claude.ai custom connector over HTTPS, and an apps package adds an inline task progress interface. To use it, you register an account on Upvote.club, subscribe to their MATE plan, and generate an API key from the site. You then double click the packaged .mcpb file, paste in your API key when prompted, and you are ready to ask Claude to promote a link. The bundle exposes six tools in total, documented in the core repository's API reference. For developers who want to build the bundle themselves rather than download a prebuilt one, the README shows how to clone the repo, run npm install, test the server locally over stdio with an API key set, and then package it into a .mcpb file using Anthropic's mcpb packaging tool. The README states the server only connects to the official Upvote.club API endpoint and links to the service's privacy policy. As with its sibling packages, this tool only becomes useful once you have a paid Upvote.club account, so it functions as a convenience wrapper for that specific commercial service rather than a general purpose tool.
