Persona MCP Server

Persona MCP Server is an MCP server that allows AI assistants such as Claude to dynamically load, switch, and manage custom personas directly from markdown files. It connects local markdown files to Model Context Protocol clients, enabling developers, prompt engineers, and writers to structure their system instructions, behavioral guidelines, and contextual roles in version-controlled text files. By reading personas directly from markdown documents, the server eliminates the need to manually copy and paste long system prompts or recreate custom instructions across separate sessions. Users can organize individual persona definitions within a repository or local directory, specifying tone, domain expertise, response formatting, and task constraints. When integrated into an MCP-supported workflow, the server allows the assistant to access persona instructions on demand, maintaining consistent system role behaviors across diverse projects and automated workflows. This dynamic management structure streamlines multi-role testing, interactive simulation setups, and domain-specific assistance while keeping prompt configurations cleanly separated, editable, and trackable within standard markdown note systems.
