# Script Execution with Code Interpreter
|
||||
|
||||
This sample demonstrates how to use **Agent Skills** with **script execution** via the hosted code interpreter.
|
||||
|
||||
## What's Different from Step01?
|
||||
|
||||
In the [basic skills sample](../Agent_Step01_BasicSkills/), skills only provide instructions and resources as text. This sample adds **script execution** — the agent can load Python scripts from skill resources and execute them using the LLM provider's built-in code interpreter.
|
||||
|
||||
This is enabled by configuring `FileAgentSkillScriptExecutor.HostedCodeInterpreter()` on the skills provider options:
|
||||
|
||||
```csharp
|
||||
var skillsProvider = new FileAgentSkillsProvider(
|
||||
skillPath: Path.Combine(AppContext.BaseDirectory, "skills"),
|
||||
options: new FileAgentSkillsProviderOptions
|
||||
{
|
||||
ScriptExecutor = FileAgentSkillScriptExecutor.HostedCodeInterpreter()
|
||||
});
|
||||
```
|
||||
|
||||
## Skills Included
|
||||
|
||||
### password-generator
|
||||
Generates secure passwords using a Python script with configurable length and complexity.
|
||||
- `scripts/generate.py` — Password generation script
|
||||
- `references/PASSWORD_GUIDELINES.md` — Recommended length and symbol sets by use case

||||

||||

```
|
||||
|
||||
## Running the Sample
|
||||
|
||||
### Prerequisites
|
||||
- .NET 10.0 SDK
|
||||
- Azure OpenAI endpoint with a deployed model that supports code interpreter
|
||||
|
||||
### Setup
|
||||
1. Set environment variables:
|
||||
```bash
|
||||
export AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
|
||||
export AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
|
||||
```
|
||||
|
||||
2. Run the sample:
|
||||
```bash
|
||||
dotnet run
|
||||
```
|
||||
|
||||
### Example
|
||||
|
||||
The sample asks the agent to generate a secure password. The agent:
|
||||
1. Loads the password-generator skill
|
||||
2. Reads the `generate.py` script via `read_skill_resource`
|
||||
3. Executes the script using the code interpreter with appropriate parameters
|
||||
4. Returns the generated password

# Password Generator
|
||||
|
||||
This skill generates secure passwords using a Python script.
|
||||
|
||||
## Usage
|
||||
|
||||
When the user requests a password:
|
||||
1. First, review `references/PASSWORD_GUIDELINES.md` to determine the recommended password length and character sets for the user's use case
|
||||
2. Load `scripts/generate.py` and adjust its parameters (length, character set) based on the guidelines and user's requirements
|
||||
3. Execute the script
|
||||
4. Present the generated password clearly

# Password Generation Guidelines
|
||||
|
||||
## General Rules
|
||||
|
||||
- Never reuse passwords across services.
|
||||
- Always use cryptographically secure randomness (e.g., `random.SystemRandom()`).
|
||||
- Avoid dictionary words, keyboard patterns, and personal information.
|
||||
|
||||
## Recommended Settings by Use Case
|
||||
|
||||
| Use Case | Min Length | Character Set | Example |
|
||||
|-----------------------|-----------|----------------------------------------|--------------------------|
|
||||
| Web account | 16 | Upper + lower + digits + symbols | `G7!kQp@2xM#nW9$z` |
|
||||
| Database credential | 24 | Upper + lower + digits + symbols | `aR3$vK8!mN2@pQ7&xL5#wY` |
|
||||
| Wi-Fi / network key | 20 | Upper + lower + digits + symbols | `Ht4&jL9!rP2#mK7@xQ` |
|
||||
| API key / token | 32 | Upper + lower + digits (no symbols) | `k8Rm3xQ7nW2pL9vT4jH6yA` |
|
||||
| Encryption passphrase | 32 | Upper + lower + digits + symbols | `Xp4!kR8@mN2#vQ7&jL9$wT` |
|
||||
|
||||
## Symbol Sets
|
||||
|
||||
- **Standard symbols**: `!@#$%^&*()-_=+`
|
||||
- **Extended symbols**: `~`{}[]|;:'",.<>?/\`
|
||||
- **Safe symbols** (URL/shell-safe): `!@#$&*-_=+`
|
||||
- If the target system restricts symbols, use only the **safe** set.

# Auth Client-Server Sample
|
||||
|
||||
This sample demonstrates how to authorize AI agents and their tools using OAuth 2.0 scopes. It shows two levels of access control: an endpoint-level scope (`agent.chat`) that gates access to the agent, and tool-level scopes (`expenses.view`, `expenses.approve`) that control what the agent can do on behalf of each user.
|
||||
|
||||
While this sample uses Keycloak to avoid complex setup in order to run the sample, Keycloak can easily be replaced with any OIDC compatible provider, including [Microsoft Entra Id](https://www.microsoft.com/security/business/identity-access/microsoft-entra-id).
|
||||
|
||||
## Overview
|
||||
|
||||
The sample has three components, all launched with a single `docker compose up`:
|
||||
|
||||
| Service | Port | Description |
|
||||
|---------|------|-------------|
|
||||
| **WebClient** | `http://localhost:8080` | Razor Pages web app with OIDC login and a chat UI that calls the AgentService |
|
||||
| **AgentService** | `http://localhost:5001` | ASP.NET Minimal API hosting an expense approval agent with scope-authorized tools |
|
||||
| **Keycloak** | `http://localhost:5002` | OIDC identity provider, auto-provisioned with realm, clients, scopes, and test users |
|
||||
|
||||
```
|
||||
┌──────────────┐ OIDC login ┌───────────┐
|
||||
│ WebClient │ ◄──────────────────► │ Keycloak │
|
||||
│ (Razor app) │ (browser flow) │ (Docker) │
|
||||
│ :8080 │ │ :5002 │
|
||||
└──────┬───────┘ └─────┬─────┘
|
||||
│ REST + Bearer token │
|
||||
▼ │
|
||||
┌───────────────┐ JWT validation ──────┘
|
||||
│ AgentService │ ◄──── (jwks from Keycloak)
|
||||
│ (Minimal API) │
|
||||
│ :5001 │
|
||||
└───────────────┘
|
||||
```
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- [Docker](https://docs.docker.com/get-docker/) and Docker Compose
|
||||
|
||||
## Configuring Environment Variables
|
||||
|
||||
The AgentService requires an OpenAI-compatible endpoint. Set these environment variables before running:
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY="<your-openai-api-key>"
|
||||
export OPENAI_MODEL="gpt-4.1-mini"
|
||||
```
|
||||
|
||||
## Running the Sample
|
||||
|
||||
### Option 1: Docker Compose (Recommended)
|
||||
|
||||
```bash
|
||||
cd dotnet/samples/05-end-to-end/AspNetAgentAuthorization
|
||||
docker compose up
|
||||
```
|
||||
|
||||
This starts Keycloak, the AgentService, and the WebClient. Wait for Keycloak to finish importing the realm (you'll see `Running the server` in the logs).
|
||||
|
||||
#### Running in GitHub Codespaces
|
||||
|
||||
This sample has been built in such a way that it can be run from GitHub Codespaces.
|
||||
The Agent Framework repository has a C# specific dev container, named "C# (.NET)", that is configured for Codespaces.
|
||||
|
||||
When running in Codespaces, the sample auto-detects the environment via
|
||||
`CODESPACE_NAME` and `GITHUB_CODESPACES_PORT_FORWARDING_DOMAIN` and configures
|
||||
Keycloak and the web client accordingly. Just make the required ports public:
|
||||
|
||||
```bash
|
||||
# Make Keycloak and WebClient ports publicly accessible
|
||||
gh codespace ports visibility 5002:public 8080:public -c $CODESPACE_NAME
|
||||
|
||||
# Start the containers (Codespaces is auto-detected)
|
||||
docker compose up
|
||||
```
|
||||
|
||||
Then open the Codespaces-forwarded URL for port 8080 (shown in the **Ports** tab) in your browser.
|
||||
|
||||
### Option 2: Run Locally
|
||||
|
||||
1. Start Keycloak:
|
||||
```bash
|
||||
docker compose up keycloak
|
||||
```
|
||||
|
||||
2. In a new terminal, start the AgentService:
|
||||
```bash
|
||||
cd Service
|
||||
dotnet run --urls "http://localhost:5001"
|
||||
```
|
||||
|
||||
3. In another terminal, start the WebClient:
|
||||
```bash
|
||||
cd RazorWebClient
|
||||
dotnet run --urls "http://localhost:8080"
|
||||
```
|
||||
|
||||
## Using the Sample
|
||||
|
||||
1. Open `http://localhost:8080` in your browser
|
||||
2. Click **Login** — you'll be redirected to Keycloak
|
||||
3. Sign in with one of the pre-configured users:
|
||||
- **`testuser` / `password`** — can chat, view expenses, and approve expenses (up to €1,000)
|
||||
- **`viewer` / `password`** — can chat and view expenses, but **cannot approve** them
|
||||
4. Try asking the agent:
|
||||
- _"Show me the pending expenses"_ — both users can do this
|
||||
- _"Approve expense #1"_ — only `testuser` can do this; `viewer` will be denied
|
||||
- _"Approve expense #3"_ — even `testuser` will be denied (€4,500 exceeds the €1,000 limit)
|
||||
|
||||
## Pre-Configured Keycloak Realm
|
||||
|
||||
The `keycloak/dev-realm.json` file auto-provisions:
|
||||
|
||||
| Resource | Details |
|
||||
|----------|---------|
|
||||
| **Realm** | `dev` |
|
||||
| **Client: agent-service** | Confidential client (the API audience) |
|
||||
| **Client: web-client** | Public client for the Razor app's OIDC login |
|
||||
| **Scope: agent.chat** | Required to call the `/chat` endpoint |
|
||||
| **Scope: expenses.view** | Required to list pending expenses |
|
||||
| **Scope: expenses.approve** | Required to approve expenses |
|
||||
| **User: testuser** | Has `agent.chat`, `expenses.view`, and `expenses.approve` scopes |
|
||||
| **User: viewer** | Has `agent.chat` and `expenses.view` scopes (no approval) |
|
||||
|
||||
### Pre-Seeded Expenses
|
||||
|
||||
The service starts with five demo expenses:
|
||||
|
||||
| # | Description | Amount | Status |
|
||||
|---|-------------|--------|--------|
|
||||
| 1 | Conference travel — Berlin | €850 | Pending |
|
||||
| 2 | Team dinner — Q4 celebration | €320 | Pending |
|
||||
| 3 | Cloud infrastructure — annual renewal | €4,500 | Pending (over limit) |
|
||||
| 4 | Office supplies — ergonomic keyboards | €675 | Pending |
|
||||
| 5 | Client gift baskets — holiday season | €980 | Pending |
|
||||
|
||||
Keycloak admin console: `http://localhost:5002` (login: `admin` / `admin`).
|
||||
|
||||
## API Endpoints
|
||||
|
||||
### POST /chat (requires `agent.chat` scope)
|
||||
|
||||
```bash
|
||||
# Get a token for testuser
|
||||
TOKEN=$(curl -s -X POST http://localhost:5002/realms/dev/protocol/openid-connect/token \
|
||||
-d "grant_type=password&client_id=web-client&username=testuser&password=password&scope=openid agent.chat expenses.view expenses.approve" \
|
||||
| jq -r '.access_token')
|
||||
|
||||
# Chat with the agent
|
||||
curl -X POST http://localhost:5001/chat \
|
||||
-H "Authorization: Bearer $TOKEN" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"message": "Show me the pending expenses"}'
|
||||
```
|
||||
|
||||
## Key Concepts Demonstrated
|
||||
|
||||
- **Endpoint-Level Authorization** — The `/chat` endpoint requires the `agent.chat` scope, gating access to the agent itself
|
||||
- **Tool-Level Authorization** — Each agent tool checks its own scope (`expenses.view`, `expenses.approve`) at runtime, so different users have different capabilities within the same chat session
|
||||
- **Scope-Based Role Mapping** — Keycloak realm roles map to OAuth scopes, allowing administrators to control which users can access which agent capabilities

# What this sample demonstrates
|
||||
|
||||
This sample demonstrates Human-in-the-Loop (HITL) capabilities with thread persistence. The agent wraps function tools with `ApprovalRequiredAIFunction` so that every tool invocation requires explicit user approval before execution. Thread state is maintained across requests using `InMemoryAgentThreadRepository`.
|
||||
|
||||
Key features:
|
||||
- Requiring human approval before executing function calls
|
||||
- Persisting conversation threads across multiple requests
|
||||
- Approving or rejecting tool invocations at runtime
|
||||
|
||||
> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before running this sample, ensure you have:
|
||||
|
||||
1. .NET 10 SDK installed
|
||||
2. An Azure OpenAI endpoint configured
|
||||
3. A deployment of a chat model (e.g., gpt-4o-mini)
|
||||
4. Azure CLI installed and authenticated (`az login`)
|
||||
|
||||
## Environment Variables
|
||||
|
||||
Set the following environment variables:
|
||||
|
||||
```powershell
|
||||
# Replace with your Azure OpenAI endpoint
|
||||
$env:AZURE_OPENAI_ENDPOINT="https://your-openai-resource.openai.azure.com/"
|
||||
|
||||
# Optional, defaults to gpt-4o-mini
|
||||
$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
The sample uses `ApprovalRequiredAIFunction` to wrap standard AI function tools. When the model decides to call a tool, the wrapper intercepts the invocation and returns a HITL approval request to the caller instead of executing the function immediately.
|
||||
|
||||
1. The user sends a message (e.g., "What is the weather in Vancouver?")
|
||||
2. The model determines a function call is needed and selects the `GetWeather` tool
|
||||
3. `ApprovalRequiredAIFunction` intercepts the call and returns an approval request containing the function name and arguments
|
||||
4. The user responds with `approve` or `reject`
|
||||
5. If approved, the function executes and the model generates a response using the result
|
||||
6. If rejected, the model generates a response without the function result
|
||||
|
||||
Thread persistence is handled by `InMemoryAgentThreadRepository`, which stores conversation history keyed by `conversation.id`. This means the HITL flow works across multiple HTTP requests as long as each request includes the same `conversation.id`.
|
||||
|
||||
> **Note:** HITL requires a stable `conversation.id` in every request so the agent can correlate the approval response with the original function call. Use the `run-requests.http` file in this directory to test the full approval flow.

# HITL (Human-in-the-Loop) Flow
|
||||
#
|
||||
# This sample requires a multi-turn conversation to demonstrate the approval flow:
|
||||
# 1. Send a request that triggers a tool call (e.g., asking about the weather)
|
||||
# 2. The agent responds with a function_call named "__hosted_agent_adapter_hitl__"
|
||||
# containing the call_id and the tool details
|
||||
# 3. Send a follow-up request with a function_call_output to approve or reject
|
||||
#
|
||||
# IMPORTANT: You must use the same conversation.id across all requests in a flow,
|
||||
# and update the call_id from step 2 into step 3.

# What this sample demonstrates
|
||||
|
||||
This sample demonstrates how to build a hosted agent that uses local C# function tools — a key advantage of code-based hosted agents over prompt agents. The agent acts as a Seattle travel assistant with a `GetAvailableHotels` tool that simulates querying a hotel availability API.
|
||||
|
||||
Key features:
|
||||
- Defining local C# functions as agent tools using `AIFunctionFactory`
|
||||
- Using `AIProjectClient` to discover the OpenAI connection from the Azure AI Foundry project
|
||||
- Building a `ChatClientAgent` with custom instructions and tools
|
||||
- Deploying to the Foundry Hosted Agent service
|
||||
|
||||
> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before running this sample, ensure you have:
|
||||
|
||||
1. .NET 10 SDK installed
|
||||
2. An Azure AI Foundry Project with a chat model deployed (e.g., gpt-4o-mini)
|
||||
3. Azure CLI installed and authenticated (`az login`)
|
||||
|
||||
## Environment Variables
|
||||
|
||||
Set the following environment variables:
|
||||
|
||||
```powershell
|
||||
# Replace with your Azure AI Foundry project endpoint
|
||||
$env:AZURE_AI_PROJECT_ENDPOINT="https://your-project.services.ai.azure.com/api/projects/your-project-name"
|
||||
|
||||
# Optional, defaults to gpt-4o-mini
|
||||
$env:MODEL_DEPLOYMENT_NAME="gpt-4o-mini"
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
1. The agent uses `AIProjectClient` to discover the Azure OpenAI connection from the project endpoint
|
||||
2. A local C# function `GetAvailableHotels` is registered as a tool using `AIFunctionFactory.Create`
|
||||
3. When users ask about hotels, the model invokes the local tool to search simulated hotel data
|
||||
4. The tool filters hotels by price and calculates total costs based on the requested dates
|
||||
5. Results are returned to the model, which presents them in a conversational format

# What this sample demonstrates
|
||||
|
||||
This sample demonstrates how to use Foundry tools with an AI agent via the `UseFoundryTools` extension. The agent is configured with two tool types: an MCP (Model Context Protocol) connection for fetching Microsoft Learn documentation and a code interpreter for running code when needed.
|
||||
|
||||
Key features:
|
||||
|
||||
- Configuring Foundry tools using `UseFoundryTools` with MCP and code interpreter
|
||||
- Connecting to an external MCP tool via a Foundry project connection
|
||||
- Using `AzureCliCredential` for Azure authentication
|
||||
- OpenTelemetry instrumentation for both the chat client and agent
|
||||
|
||||
> For common prerequisites and setup instructions, see the [Hosted Agent Samples README](../README.md).
|
||||
|
||||
## Prerequisites
|
||||
|
||||
In addition to the common prerequisites:
|
||||
|
||||
1. An **Azure AI Foundry project** with a chat model deployed (e.g., `gpt-5.2`, `gpt-4o-mini`)
|
||||
2. The **Azure AI Developer** role assigned on the Foundry resource (includes the `agents/write` data action required by `UseFoundryTools`)
|
||||
3. An **MCP tool connection** configured in your Foundry project pointing to `https://learn.microsoft.com/api/mcp`
|
||||
|
||||
## Environment Variables
|
||||
|
||||
In addition to the common environment variables in the root README:
|
||||
|
||||
```powershell
|
||||
# Your Azure AI Foundry project endpoint (required by UseFoundryTools)
|
||||
$env:AZURE_AI_PROJECT_ENDPOINT="https://your-resource.services.ai.azure.com/api/projects/your-project"
|
||||
|
||||
# Chat model deployment name (defaults to gpt-4o-mini if not set)
|
||||
$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
|
||||
|
||||
# The MCP tool connection name (just the name, not the full ARM resource ID)
|
||||
$env:MCP_TOOL_CONNECTION_ID="SampleMCPTool"
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
1. An `AzureOpenAIClient` is created with `AzureCliCredential` and used to get a chat client
|
||||
2. The chat client is wrapped with `UseFoundryTools` which registers two Foundry tool types:
|
||||
- **MCP connection**: Connects to an external MCP server (Microsoft Learn) via the project connection name, providing documentation fetch and search capabilities
|
||||
- **Code interpreter**: Allows the agent to execute code snippets when needed
|
||||
3. `UseFoundryTools` resolves the connection using `AZURE_AI_PROJECT_ENDPOINT` internally
|
||||
4. A `ChatClientAgent` is created with instructions guiding it to use the MCP tools for documentation queries
|
||||
5. The agent is hosted using `RunAIAgentAsync` which exposes the OpenAI Responses-compatible API endpoint

# Hosted Agent Samples
|
||||
|
||||
These samples demonstrate how to build and host AI agents using the [Azure AI AgentServer SDK](https://learn.microsoft.com/en-us/dotnet/api/overview/azure/ai.agentserver.agentframework-readme). Each sample can be run locally and deployed to Microsoft Foundry as a hosted agent.
|
||||
|
||||
## Samples
|
||||
|
||||
| Sample | Description |
|
||||
|--------|-------------|
|
||||
| [`AgentWithTools`](./AgentWithTools/) | Foundry tools (MCP + code interpreter) via `UseFoundryTools` |
|
||||
| [`AgentWithLocalTools`](./AgentWithLocalTools/) | Local C# function tool execution (Seattle hotel search) |
|
||||
| [`AgentThreadAndHITL`](./AgentThreadAndHITL/) | Human-in-the-loop with `ApprovalRequiredAIFunction` and thread persistence |
|
||||
| [`AgentWithHostedMCP`](./AgentWithHostedMCP/) | Hosted MCP server tool (Microsoft Learn search) |
|
||||
| [`AgentWithTextSearchRag`](./AgentWithTextSearchRag/) | RAG with `TextSearchProvider` (Contoso Outdoors) |
|
||||
| [`AgentsInWorkflows`](./AgentsInWorkflows/) | Sequential workflow pipeline (translation chain) |
|
||||
|
||||
## Common Prerequisites
|
||||
|
||||
Before running any sample, ensure you have:
|
||||
|
||||
1. **.NET 10 SDK** or later — [Download](https://dotnet.microsoft.com/download/dotnet/10.0)
|
||||
2. **Azure CLI** installed — [Install guide](https://learn.microsoft.com/cli/azure/install-azure-cli)
|
||||
3. **Azure OpenAI** or **Azure AI Foundry project** with a chat model deployed (e.g., `gpt-4o-mini`)
|
||||
|
||||
### Authenticate with Azure CLI
|
||||
|
||||
All samples use `AzureCliCredential` for authentication. Make sure you're logged in:
|
||||
|
||||
```powershell
|
||||
az login
|
||||
az account show # Verify the correct subscription
|
||||
```
|
||||
|
||||
### Common Environment Variables
|
||||
|
||||
Most samples require one or more of these environment variables:
|
||||
|
||||
| Variable | Used By | Description |
|
||||
|----------|---------|-------------|
|
||||
| `AZURE_OPENAI_ENDPOINT` | Most samples | Your Azure OpenAI resource endpoint URL |
|
||||
| `AZURE_OPENAI_DEPLOYMENT_NAME` | Most samples | Chat model deployment name (defaults to `gpt-4o-mini`) |
|
||||
| `AZURE_AI_PROJECT_ENDPOINT` | AgentWithTools, AgentWithLocalTools | Azure AI Foundry project endpoint |
|
||||
| `MCP_TOOL_CONNECTION_ID` | AgentWithTools | Foundry MCP tool connection name |
|
||||
| `MODEL_DEPLOYMENT_NAME` | AgentWithLocalTools | Chat model deployment name (defaults to `gpt-4o-mini`) |
|
||||
|
||||
See each sample's README for the specific variables required.
|
||||
|
||||
## Azure AI Foundry Setup (for samples that use Foundry)
|
||||
|
||||
Some samples (`AgentWithTools`, `AgentWithLocalTools`) connect to an Azure AI Foundry project. If you're using these samples, you'll need additional setup.
|
||||
|
||||
### Azure AI Developer Role
|
||||
|
||||
The `UseFoundryTools` extension requires the **Azure AI Developer** role on the Cognitive Services resource. Even if you created the project, you may not have this role by default.
|
||||
|
||||
```powershell
|
||||
az role assignment create `
|
||||
--role "Azure AI Developer" `
|
||||
--assignee "your-email@microsoft.com" `
|
||||
--scope "/subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.CognitiveServices/accounts/{account-name}"
|
||||
```
|
||||
|
||||
> **Note**: You need **Owner** or **User Access Administrator** permissions on the resource to assign roles. If you don't have this, you may need to request JIT (Just-In-Time) elevated access via [Azure PIM](https://portal.azure.com/#view/Microsoft_Azure_PIMCommon/ActivationMenuBlade/~/aadmigratedresource).
|
||||
|
||||
For more details on permissions, see [Azure AI Foundry Permissions](https://aka.ms/FoundryPermissions).
|
||||
|
||||
### Creating an MCP Tool Connection
|
||||
|
||||
The `AgentWithTools` sample requires an MCP tool connection configured in your Foundry project:
|
||||
|
||||
1. Go to the [Azure AI Foundry portal](https://ai.azure.com)
|
||||
2. Navigate to your project
|
||||
3. Go to **Connected resources** → **+ New connection** → **Model Context Protocol tool**
|
||||
4. Fill in:
|
||||
- **Name**: `SampleMCPTool` (or any name you prefer)
|
||||
- **Remote MCP Server endpoint**: `https://learn.microsoft.com/api/mcp`
|
||||
- **Authentication**: `Unauthenticated`
|
||||
5. Click **Connect**
|
||||
|
||||
The connection **name** (e.g., `SampleMCPTool`) is used as the `MCP_TOOL_CONNECTION_ID` environment variable.
|
||||
|
||||
> **Important**: Use only the connection **name**, not the full ARM resource ID.
|
||||
|
||||
## Running a Sample
|
||||
|
||||
Each sample runs as a standalone hosted agent on `http://localhost:8088/`:
|
||||
|
||||
```powershell
|
||||
cd <sample-directory>
|
||||
dotnet run
|
||||
```
|
||||
|
||||
### Interacting with the Agent
|
||||
|
||||
Each sample includes a `run-requests.http` file for testing with the [VS Code REST Client](https://marketplace.visualstudio.com/items?itemName=humao.rest-client) extension, or you can use PowerShell:
|
||||
|
||||
```powershell
|
||||
$body = @{ input = "Your question here" } | ConvertTo-Json
|
||||
Invoke-RestMethod -Uri "http://localhost:8088/responses" -Method Post -Body $body -ContentType "application/json"
|
||||
```
|
||||
|
||||
## Deploying to Microsoft Foundry
|
||||
|
||||
Each sample includes a `Dockerfile` and `agent.yaml` for deployment. To deploy your agent to Microsoft Foundry, follow the [hosted agents deployment guide](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents).
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### `PermissionDenied` — lacks `agents/write` data action
|
||||
|
||||
Assign the **Azure AI Developer** role to your user. See [Azure AI Developer Role](#azure-ai-developer-role) above.
|
||||
|
||||
### `Project connection ... was not found`
|
||||
|
||||
Make sure `MCP_TOOL_CONNECTION_ID` contains only the connection **name** (e.g., `SampleMCPTool`), not the full ARM resource ID path.
|
||||
|
||||
### `AZURE_AI_PROJECT_ENDPOINT must be set`
|
||||
|
||||
The `UseFoundryTools` extension requires `AZURE_AI_PROJECT_ENDPOINT`. Set it to your Foundry project endpoint (e.g., `https://your-resource.services.ai.azure.com/api/projects/your-project`).
|
||||
|
||||
### Multi-framework error when running `dotnet run`
|
||||
|
||||
If you see "Your project targets multiple frameworks", specify the framework:
|
||||
|
||||

|
||||
dotnet run --framework net10.0
