Promethic MCP
Public packaging and docs for the Promethic hosted MCP server.
Promethic is a prompt library: store versioned prompts where you set the model, switch models, and dial API-only settings (reasoning, verbosity, and other dials). Text, image, and JSON. Edit the output as you work; it tracks those edits and successful copy/download. Refine proposes the next version.
