dotnet add package Novior.MentorAgent.Abstractions
```

## Values

| Value | Number | Description |
|---|---|---|
| `Published` | 0 | In every caller's `tools/list`. |
| `PublishedToRoles` | 1 | In the `tools/list` of the callers `McpCallerPrincipal` identifies as holding one of its roles. |
| `Withheld` | 2 | Never published: it asks for confirmation, the `RequiresApproval` predicate keeps it back, or it requires roles and no `McpCallerPrincipal` is set. |
| `NotServed` | 3 | The MCP server does not serve it: the host does not map the server (`MapMentorAgentMcp`), the action belongs to a specialist or a team, or its class is not registered in the container. |
