Microsoft Foundry 的代理程式 Code Interpreter 工具

在 Python SDK 中使用代理程式與程式碼直譯工具的範例

以下的 Python 範例展示了如何將程式碼直譯工具加入工具箱、將工具箱附加到代理程式、上傳 CSV 檔案以供分析，以及根據資料請求長條圖。 選擇 Prompt Agents 以使用 Azure AI Projects SDK 建立伺服器端提示代理，或選擇 Hosted Agents 使用 Agent Framework FoundryChatClient 建立臨時且進行中的代理。

此範例展示了完整的工作流程：上傳檔案、建立啟用 Code Interpreter 的代理程式、請求資料視覺化，並下載產生的圖表。

用 Java 的程式碼直譯器建立圖表

對大多數代理來說，透過 工具箱 加入程式碼直譯器工具，並將工具箱附加到你的代理上作為 MCP 工具。 Java SDK 目前尚未公開工具箱建立 API，因此請使用目前支援的方法之一（Python、REST API、C#、TypeScript 或 Foundry 入口網站）來建立工具箱。 工具箱建立完成後，從你的 Java 代理中引用其 MCP 端點作為 McpTool。 以下範例將程式碼直譯工具箱 MCP 端點附加到代理上。

新增相依性至您的pom.xml：

Response: Here is the bar chart showing quarterly revenue for 2025 with Q1 ($2.1M), Q2 ($2.8M), Q3 ($3.2M), and Q4 ($2.9M) displayed in blue with data labels.

代理程式透過工具箱 MCP 端點使用 Code Interpreter，使用 matplotlib 撰寫 Python 程式碼產生圖表，並在沙盒環境中執行程式碼。 若要上傳 CSV 檔案並下載產生圖表的範例，請從本文頂端的語言選擇器中選擇 Python 或 TypeScript。 更多範例請參考 Azure AI 代理 Java SDK 範例 。

用 REST API 的程式碼直譯器建立圖表

以下範例展示了如何上傳 CSV 檔案、使用 Code Interpreter 建立代理程式、請求圖表，以及下載產生的檔案。

先決條件

設定以下環境變數：

• FOUNDRY_PROJECT_ENDPOINT： 你的專案端點網址。
• AGENT_TOKEN：Foundry 的持有人權杖。

取得存取權憑證：

export AGENT_TOKEN=$(az account get-access-token --scope "https://ai.azure.com/.default" --query accessToken -o tsv)

在工具箱中使用 Code Interpreter

若要透過工具箱上傳檔案供 Code Interpreter 使用，請使用 標頭，將檔案上傳至 POST {account_endpoint}/openai/v1/files Files 端點（x-aml-project-id）。 與提示代理流程不同，透過專案範圍的 Files 端點（/api/projects/{name}/openai/v1/files）上傳的檔案會收到一個 owner_id，而工具箱容器無法驗證它，因此 tools/call 會因所有權驗證錯誤而失敗。

1. 從 Azure Resource Manager 取得專案 GUID。 請使用properties.amlWorkspace.internalId (帶連字號的 UUID 格式)，而不是使用properties.internalId (不含連字號 - 工具箱容器會拒絕)：

   ARM_TOKEN=$(az account get-access-token --query accessToken -o tsv)
   PROJECT_GUID=$(curl -s -H "Authorization: Bearer $ARM_TOKEN" \
     "https://management.azure.com/subscriptions/{sub}/resourceGroups/{rg}/providers/Microsoft.CognitiveServices/accounts/{account}/projects/{project}?api-version=2025-06-01" \
     | jq -r '.properties.amlWorkspace.internalId')
   

2. 在帳號（資源）層級上傳檔案，標頭如下 x-aml-project-id ：

   cat > synthetic-company-financial-results.csv <<'CSV'
   name,sector,operating_profit
   SkyBridge Logistics,TRANSPORTATION,185.2
   Velocity Rail Freight,TRANSPORTATION,310.2
   AeroJet Airlines,TRANSPORTATION,510.6
   CSV
   
   TOKEN=$(az account get-access-token --scope https://ai.azure.com/.default --query accessToken -o tsv)
   curl -X POST "https://{account}.services.ai.azure.com/openai/v1/files" \
     -H "Authorization: Bearer $TOKEN" \
     -H "x-aml-project-id: $PROJECT_GUID" \
     -F "purpose=assistants" \
     -F "file=@synthetic-company-financial-results.csv"
   rm synthetic-company-financial-results.csv
   

回傳的檔案 id 就是你在工具設定中提供的 <FILE_ID> 數值。 檔案會掛載在 /mnt/data/{file-id}-{original-filename} 的沙盒中。

將程式碼直譯器加入工具箱

透過建立工具箱來新增程式碼直譯器，然後將工具箱附加到你的代理程式中作為 MCP 工具。 欲了解更多資訊，請參閱 「什麼是工具箱？」

• 建立包含程式碼直譯工具的工具箱：

  curl --request POST \
    --url "$FOUNDRY_PROJECT_ENDPOINT/toolboxes/code-interpreter-toolbox/versions?api-version=v1" \
    -H "Authorization: Bearer $AGENT_TOKEN" \
    -H "Content-Type: application/json" \
    --data '{
      "description": "Toolbox with the code interpreter tool",
      "tools": [
        {
          "type": "code_interpreter",
          "container": {
            "type": "auto",
            "file_ids": ["<FILE_ID>"]
          }
        }
      ]
    }'
  

  工具箱在 處暴露一個與 MCP 相容的端點 $FOUNDRY_PROJECT_ENDPOINT/toolboxes/code-interpreter-toolbox/versions/<version>/mcp?api-version=v1，其中 <version> 是前一次呼叫回傳的版本。

• 建立一個指向工具箱端點的遠端工具專案連線，並使用使用者 Entra 權杖，以便傳遞呼叫者的身分識別 (對象為https://ai.azure.com)。

  azd ai connection create code-interpreter-toolbox-conn \
    --kind remote-tool \
    --target "$FOUNDRY_PROJECT_ENDPOINT/toolboxes/code-interpreter-toolbox/versions/<version>/mcp?api-version=v1" \
    --auth-type user-entra-token \
    --audience https://ai.azure.com
  

用程式碼直譯器工具箱建立代理程式

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/agents?api-version=v1" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "name": "chart-agent",
    "definition": {
      "kind": "prompt",
      "model": "<MODEL_DEPLOYMENT>",
      "instructions": "You are a data visualization assistant. When asked to create charts, write and run Python code using matplotlib to generate them.",
      "tools": [
        {
          "type": "mcp",
          "server_label": "toolbox",
          "server_url": "'$FOUNDRY_PROJECT_ENDPOINT'/toolboxes/code-interpreter-toolbox/versions/<version>/mcp?api-version=v1",
          "require_approval": "never",
          "project_connection_id": "code-interpreter-toolbox-conn"
        }
      ]
    }
  }'

產生圖表

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "agent_reference": {"type": "agent_reference", "name": "chart-agent"},
    "input": "Create a bar chart of operating profit by company for the TRANSPORTATION sector from the uploaded CSV file. Use a blue color scheme and add data labels."
  }'

回覆中包含 container_file_citation 註解，其中包含產生的檔案細節。 從註解中儲存 container_id 和 file_id 值。

下載生成的圖表

curl -X GET "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/containers/<CONTAINER_ID>/files/<FILE_ID>/content" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  --output chart.png

清除

curl -X DELETE "$FOUNDRY_PROJECT_ENDPOINT/agents/chart-agent?api-version=v1" \
  -H "Authorization: Bearer $AGENT_TOKEN"
