Hosted-Toolbox
A hosted Foundry agent that loads tools from a Foundry Toolbox via the AF Foundry hosting bridge.
The agent declares one FoundryAITool.CreateHostedMcpToolbox(name) marker; AddFoundryToolboxes(name) registers a FoundryToolboxService that resolves the marker into the individual MCP tools the toolbox bundles, connecting to the Foundry Toolboxes MCP proxy at startup and discovering tools via tools/list.
Prerequisites
- A Microsoft Foundry project with a Toolbox configured.
- Azure CLI logged in (
az login). - Set environment variables:
AZURE_AI_PROJECT_ENDPOINT(local-dev) orFOUNDRY_PROJECT_ENDPOINT(auto-injected in hosted containers)AZURE_AI_MODEL_DEPLOYMENT_NAME(defaultgpt-4o)TOOLBOX_NAME(defaultmy-toolbox)
The Foundry.Hosting package builds the toolbox proxy URL from FOUNDRY_PROJECT_ENDPOINT as {FOUNDRY_PROJECT_ENDPOINT}/toolboxes/{TOOLBOX_NAME}/mcp?api-version=v1 per tools-integration-spec.md §2–§3.
Run
dotnet run --tl:off
