ChatGPT writes drafts via MCP, Claude edits them — two models, one shared board
BarcodeCutter · reddit · 2026-10-02
- A developer demonstrated an MCP workflow in his product Soul/Box: ChatGPT searched Reddit, wrote post drafts, and dropped them onto the Box board via MCP; then Claude, connected to the same Box, read the cards and edited them — no copy-pasting between models.
- The AI side is plain MCP: read the Box, keep a record, put a card on the board, join a room.
- Design principle: the AI can propose but can't rewrite who you are — profile claims require the user's swipe approval. The product is free, and he asks MCP builders whether agents should write learned facts directly or queue them for approval.
