Saída esperada

Ao ser invocado, o agente hospedado consulta o servidor MCP do Microsoft Learn por meio do endpoint Toolbox para obter trechos de documentação e respostas:

User: How does one create an Azure storage account using the az CLI?

Agent: To create an Azure storage account using the az CLI, run: `az storage account create --name <name> --resource-group <rg> --location <region> --sku Standard_LRS` ...

Criar um agente usando a ferramenta MCP com autenticação de conexão de projeto

O exemplo de TypeScript a seguir demonstra como adicionar um servidor MCP autenticado a uma caixa de ferramentas, anexar o ponto de extremidade MCP da caixa de ferramentas a um agente, enviar solicitações que disparam fluxos de trabalho de aprovação mcp, lidar com solicitações de aprovação e limpar recursos. Para obter uma versão do JavaScript, consulte o código sample no SDK do Azure do repositório JavaScript no GitHub.

Usar a ferramenta MCP com a API REST

Os exemplos a seguir mostram como criar um agente com a ferramenta MCP e chamá-lo usando a API de Respostas. Se a resposta incluir um item de saída com type definido como mcp_approval_request, envie uma solicitação de acompanhamento que inclua um mcp_approval_response item.

Pré-requisitos

Defina estas variáveis de ambiente:

• FOUNDRY_PROJECT_ENDPOINT: URL do endpoint do projeto.
• FOUNDRY_MODEL_DEPLOYMENT_NAME: Seu nome de implantação do modelo.
• AGENT_TOKEN: um token de portador para o Foundry.
• MCP_PROJECT_CONNECTION_NAME (opcional): o nome da conexão do projeto MCP.

Obtenha um token de acesso:

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

Se o servidor MCP no toolbox não exigir autenticação, omita project_connection_id da definição da ferramenta no toolbox. A ferramenta MCP do agente ainda utiliza project_connection_id para a conexão de ferramenta remota ao endpoint da toolbox.

1. Criar uma caixa de ferramentas com o servidor MCP

A maneira recomendada de adicionar um servidor MCP é por meio de uma caixa de ferramentas e anexar a caixa de ferramentas ao agente como uma ferramenta MCP. Veja o que é uma caixa de ferramentas?

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/toolboxes/mcp-server-toolbox/versions?api-version=v1" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "description": "Toolbox with the Azure REST API specifications MCP server",
    "tools": [
      {
        "type": "mcp",
        "server_label": "api-specs",
        "server_url": "https://gitmcp.io/Azure/azure-rest-api-specs",
        "require_approval": "never"
      }
    ]
  }'

O kit de ferramentas expõe um endpoint compatível com MCP em $FOUNDRY_PROJECT_ENDPOINT/toolboxes/mcp-server-toolbox/versions/<version>/mcp?api-version=v1, em que <version> é a versão retornada pela chamada anterior.

2. Criar uma conexão de ferramenta remota com a caixa de ferramentas

Crie uma conexão de projeto de ferramenta remota que aponte para o endpoint da caixa de ferramentas. Use um token de usuário do Entra para que a identidade do chamador seja transmitida (público-alvo https://ai.azure.com):

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

3. Criar um agente MCP

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/agents?api-version=v1" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "name": "<AGENT_NAME>-mcp",
    "description": "MCP agent",
    "definition": {
      "kind": "prompt",
      "model": "'$FOUNDRY_MODEL_DEPLOYMENT_NAME'",
      "instructions": "You are a helpful agent that can use MCP tools to assist users. Use the available MCP tools to answer questions and perform tasks.",
      "tools": [
        {
          "type": "mcp",
          "server_label": "toolbox",
          "server_url": "'$FOUNDRY_PROJECT_ENDPOINT'/toolboxes/mcp-server-toolbox/versions/<version>/mcp?api-version=v1",
          "require_approval": "always",
          "project_connection_id": "mcp-server-toolbox-conn"
        }
      ]
    }
  }'

Para usar um servidor MCP autenticado dentro da caixa de ferramentas, adicione "project_connection_id": "'$MCP_PROJECT_CONNECTION_NAME'" à definição da ferramenta de caixa de ferramentas. Mude server_url para o endpoint do servidor autenticado (por exemplo, https://api.githubcopilot.com/mcp).

4. Criar uma resposta

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "agent": {"type": "agent_reference", "name": "<AGENT_NAME>-mcp"},
    "input": "Please summarize the Azure REST API specifications Readme"
  }'

Se a resposta incluir um item de saída com type definido como mcp_approval_request, copie o item id de solicitação de aprovação como APPROVAL_REQUEST_ID. Copie também a resposta id de nível superior como PREVIOUS_RESPONSE_ID.

5. Enviar uma resposta de aprovação

Se a ferramenta MCP exigir aprovação, envie uma solicitação de acompanhamento:

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "previous_response_id": "'$PREVIOUS_RESPONSE_ID'",
    "input": [
      {
        "type": "mcp_approval_response",
        "approval_request_id": "'$APPROVAL_REQUEST_ID'",
        "approve": true
      }
    ]
  }'

6. Limpar os recursos

Exclua o agente:

curl -X DELETE "$FOUNDRY_PROJECT_ENDPOINT/agents/<AGENT_NAME>-mcp?api-version=v1" \
  -H "Authorization: Bearer $AGENT_TOKEN"

from time import sleep
from azure.identity import DefaultAzureCredential
from azure.ai.projects import AIProjectClient

PROJECT_ENDPOINT = "your_project_endpoint"
AGENT_NAME = "your_mcp_agent_name"

project = AIProjectClient(
    endpoint=PROJECT_ENDPOINT,
    credential=DefaultAzureCredential(),
)
openai = project.get_openai_client()

# Start a background response. It returns immediately with status "queued".
response = openai.responses.create(
    extra_body={
        "agent_reference": {
            "name": AGENT_NAME,
            "type": "agent_reference",
        }
    },
    input="Run the long-running task and summarize the result.",
    background=True,
)

# Poll the response ID until the MCP tool call completes.
while response.status in ("queued", "in_progress"):
    sleep(5)
    response = openai.responses.retrieve(response.id)

print(response.output_text)

using Azure.Identity;
using Azure.AI.Projects;

var projectEndpoint = "your_project_endpoint";
var agentName = "your_mcp_agent_name";

AIProjectClient projectClient = new(
    endpoint: new Uri(projectEndpoint),
    tokenProvider: new DefaultAzureCredential());

ProjectResponsesClient responsesClient
    = projectClient.ProjectOpenAIClient.GetProjectResponsesClientForAgent(agentName);

// Start a background response. It returns immediately with status "queued".
ResponseResult response = await responsesClient.CreateResponseAsync(
    new CreateResponseOptions
    {
        InputItems = { ResponseItem.CreateUserMessageItem(
            "Run the long-running task and summarize the result.") },
        Background = true,
    });

// Poll the response ID until the MCP tool call completes.
while (response.Status is "queued" or "in_progress")
{
    await Task.Delay(5000);
    response = await responsesClient.RetrieveResponseAsync(response.Id);
}
Console.WriteLine(response.GetOutputText());

import { DefaultAzureCredential } from "@azure/identity";
import { AIProjectClient } from "@azure/ai-projects";

const PROJECT_ENDPOINT = "your_project_endpoint";
const AGENT_NAME = "your_mcp_agent_name";

const project = new AIProjectClient(PROJECT_ENDPOINT, new DefaultAzureCredential());
const openai = project.getOpenAIClient();

// Start a background response. It returns immediately with status "queued".
let response = await openai.responses.create(
  {
    input: "Run the long-running task and summarize the result.",
    background: true,
  },
  { body: { agent_reference: { name: AGENT_NAME, type: "agent_reference" } } },
);

// Poll the response ID until the MCP tool call completes.
while (response.status === "queued" || response.status === "in_progress") {
  await new Promise((r) => setTimeout(r, 5000));
  response = await openai.responses.retrieve(response.id);
}
console.log(response.output_text);

import com.azure.ai.agents.*;
import com.azure.ai.agents.models.AgentReference;
import com.azure.ai.agents.models.AzureCreateResponseOptions;
import com.azure.identity.DefaultAzureCredentialBuilder;
import com.openai.models.responses.Response;
import com.openai.models.responses.ResponseCreateParams;

String projectEndpoint = "your_project_endpoint";
String agentName = "your_mcp_agent_name";

AgentsClientBuilder builder = new AgentsClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .endpoint(projectEndpoint);
ResponsesClient responsesClient = builder.buildResponsesClient();

AgentReference agentRef = new AgentReference(agentName);

// Start a background response. It returns immediately with status "queued".
Response response = responsesClient.createAzureResponse(
    new AzureCreateResponseOptions()
        .setAgentReference(agentRef)
        .setBackground(true),
    ResponseCreateParams.builder()
        .input("Run the long-running task and summarize the result."));

// Poll the response ID until the MCP tool call completes.
while (response.status().equals("queued") || response.status().equals("in_progress")) {
    Thread.sleep(5000);
    response = responsesClient.getAzureResponse(response.id());
}
System.out.println(response.output());

Crie uma resposta em segundo plano. A solicitação retorna imediatamente com uma resposta id e um status de queued:

curl -X POST "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AGENT_TOKEN" \
  -d '{
    "agent": {"type": "agent_reference", "name": "<AGENT_NAME>-mcp"},
    "input": "Run the long-running task and summarize the result.",
    "background": true
  }'

Copie a resposta id do resultado e, em seguida, sonde-a até que status seja completed:

curl "$FOUNDRY_PROJECT_ENDPOINT/openai/v1/responses/$RESPONSE_ID" \
  -H "Authorization: Bearer $AGENT_TOKEN"

Quando status é completed, a output matriz contém o resultado da chamada da ferramenta MCP e a mensagem do assistente final.
