fallmind-v2-mcp

MCP server for foldkit — exposes the 7-prime spine, 7 κ-bands, and 6 fold operations as native tools + resources in any MCP client (Claude Code, Claude Desktop, Cursor, Cline, Windsurf, etc.).

Second canonical exemplar of the AI-Native Solutions estate -mcp companion shape. Fork this repo verbatim to build companions for any of the ~295 estate substrates.
