⚠️ DEPRECATION NOTICE ⚠️
hexai-mcp-server is currently EXPERIMENTAL and NOT ACTIVELY MAINTAINED.
The author does not have a real use case for this MCP server at this time.
Prompts are now managed through slash commands and meta-commands in the
main hexai agent system, making this MCP server's prompt management
functionality redundant.
This code is kept in the repository for potential future enhancements
(possibly adding more useful functionality than prompt management), but
no guarantees are made about its stability or continued support.
Use at your own risk.
