MCP server for unified prompt artifacts -- skills, slash commands, and rules.
Skills are reusable prompt files stored in the project's `.aether/skills/` directory. This server exposes tools for loading skills and managing notes, and implements the MCP prompts protocol so skills can be invoked as slash commands.
# Construction
```rust,ignore
use mcp_servers::SkillsMcp;
let server = SkillsMcp::new(vec!["/my/project/.aether".into()]);
// From CLI args (e.g. --dir ~/.aether)
let server = SkillsMcp::from_args(vec!["--dir".into(), "/home/user/.aether".into()]).unwrap();
// Multiple directories (last wins on name collision)
let server = SkillsMcp::new(vec!["/shared/skills".into(), "/my/project/.aether".into()]);
let server = SkillsMcp::from_args(vec![
"--dir".into(), "/shared/skills".into(),
"--dir".into(), "/my/project/.aether".into(),
]).unwrap();
```
# Tools provided
- **`get_skills`** -- Load skill files from the skills directory. Optionally filter by name.
- **`save_note`** -- Save a note (creates or updates a file in the notes directory).
- **`search_notes`** -- Search saved notes by keyword.
# Prompts
The server also implements the MCP prompts protocol, listing available skills as invocable prompts. This allows MCP clients to present skills as slash commands with argument substitution.
