Vocab Cards — MCP server

https://mcp.vocabcards.app/<key> is an MCP server (Streamable HTTP). Give your address to an AI assistant that takes MCP servers — in Claude: Settings → Connectors → Add custom connector — and the assistant can add words and sentences to the word file of the account the key belongs to.
Keys are made and revoked under AI assistant on the Account page at https://vocabcards.app. Anyone with the address can add to the file: keep it like a password.
