rankcusp is a Model Context Protocol (MCP) server: App Store keyword ranks, the 11-30 cusp band, metadata audits and rival positions. In practice that means any MCP-compatible AI assistant can call rankcusp's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://rankcusp.com/api/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
rankcusp is listed under Development on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
