LLM pricing where every rate carries the vendor page it was read from and the date it was read, and rates two sources disagree about are flagged rather than quietly resolved. 69 models across 12 providers, re-checked against the vendors every morning; most read against a vendor's own page, the rest labelled feed-sourced rather than laundered into a first-party claim. 3 tools: `get_price`, `estimate_cost`, `find_cheaper`. Transport: stdio. Clients: Claude Code, Claude Desktop, Cursor, Windsurf, VS Code. Install: `npx -y @promptspend/mcp`. No API key, no accounts. Also a keyless CORS-open REST API (https://promptspend.dev) and a VS Code extension. Homepage: https://promptspend.com. Docs: https://github.com/AndrewAvery7/promptspend/blob/main/mcp/README.md.
