MentorHostedTools enum

Provider-hosted tools the coordinator may use (roadmap #15 — Agent Framework hosted tools).

On this page

Unlike [MentorAction] function tools, these are not executed by your application: they run on the model provider's infrastructure during inference. MentorAgent only declares them, which is exactly what the Agent Framework does (HostedWebSearchTool, HostedCodeInterpreterTool, HostedFileSearchTool, HostedImageGenerationTool, HostedMcpServerTool from Microsoft.Extensions.AI).

⚠️ Availability depends on the provider. Azure OpenAI / OpenAI Responses clients support the full set; the Chat Completions client supports web search only. Enabling a tool the provider does not support makes the provider reject the call — see the package README.

public enum MentorHostedTools

dotnet add package Novior.MentorAgent.Abstractions

Values

Value	Number	Description
`None`	0	No hosted tools (default).
`WebSearch`	1	Web search — the provider searches the web for up-to-date information (current events, documentation, anything past the model's training cut-off).
`CodeInterpreter`	2	Code interpreter — the provider writes and runs code in its own sandbox for exact computation, data analysis and file processing. The code never runs on your servers.
`FileSearch`	4	File search — the provider searches documents you uploaded to its vector store(s). Requires `MentorOptions.FileSearchVectorStoreIds`.
`ImageGeneration`	8	Image generation — the provider generates images from the conversation and returns them inline. The generated images are rendered in the message bubble.
`HostedMcp`	16	Hosted MCP — the provider connects to a remote MCP server and calls its tools during inference (as opposed to `MentorOptions.McpServers`, where your process is the MCP client). Requires `MentorOptions.HostedMcpServers`.
