The LoneScale MCP server lets AI assistants (Claude, Cursor, ChatGPT, custom agents) call LoneScale’s enrichment and sourcing capabilities as tools — directly from a chat, no glue code required. It implements the Model Context Protocol over Streamable HTTP and authenticates users via OAuth 2.0 with PKCE. Behind the scenes, every tool call uses the same LoneScale Public API documented elsewhere on this site.Documentation Index
