Managed Agents — cURL / Raw HTTP

Use these examples when the user needs raw HTTP requests or is working without an SDK.

Setup

export ANTHROPIC_API_KEY="your-api-key"

# Common headers
HEADERS=(
  -H "Content-Type: application/json"
  -H "x-api-key: $ANTHROPIC_API_KEY"
  -H "anthropic-version: 2023-06-01"
  -H "anthropic-beta: managed-agents-2026-04-01"
)

Create an Environment

curl -X POST https://api.anthropic.com/v1/environments \
  "${HEADERS[@]}" \
  -d '{
    "name": "my-dev-env",
    "config": {
      "type": "cloud",
      "networking": { "type": "unrestricted" }
    }
  }'

With restricted networking

curl -X POST https://api.anthropic.com/v1/environments \
  "${HEADERS[@]}" \
  -d '{
    "name": "restricted-env",
    "config": {
      "type": "cloud",
      "networking": {
        "type": "package_managers_and_custom",
        "allowed_hosts": ["api.example.com"]
      }
    }
  }'

Create an Agent (required first step)

⚠️ There is no inline agent config. Under managed-agents-2026-04-01, model/system/tools are top-level fields on POST /v1/agents, not on the session. Always create the agent first — the session only takes "agent": {"type": "agent", "id": "..."}.

Minimal

# 1. Create the agent
curl -X POST https://api.anthropic.com/v1/agents \
  "${HEADERS[@]}" \
  -d '{
    "name": "Coding Assistant",
    "model": "claude-opus-4-7",
    "tools": [{ "type": "agent_toolset_20260401" }]
  }'
# → { "id": "agent_abc123", ... }

# 2. Start a session
curl -X POST https://api.anthropic.com/v1/sessions \
  "${HEADERS[@]}" \
  -d '{
    "agent": { "type": "agent", "id": "agent_abc123", "version": "1772585501101368014" },
    "environment_id": "env_abc123"
  }'

With system prompt, custom tools, and GitHub repo

# 1. Create the agent
curl -X POST https://api.anthropic.com/v1/agents \
  "${HEADERS[@]}" \
  -d '{
    "name": "Code Reviewer",
    "model": "claude-opus-4-7",
    "system": "You are a senior code reviewer. Be thorough and constructive.",
    "tools": [
      { "type": "agent_toolset_20260401" },
      {
        "type": "custom",
        "name": "run_linter",
        "description": "Run the project linter on a file",
        "input_schema": {
          "type": "object",
          "properties": {
            "file_path": { "type": "string", "description": "Path to lint" }
          },
          "required": ["file_path"]
        }
      }
    ]
  }'

# 2. Start a session with the repo mounted
curl -X POST https://api.anthropic.com/v1/sessions \
  "${HEADERS[@]}" \
  -d '{
    "agent": { "type": "agent", "id": "agent_abc123", "version": "1772585501101368014" },
    "environment_id": "env_abc123",
    "title": "Code review session",
    "resources": [
      {
        "type": "github_repository",
        "url": "https://github.com/owner/repo",
        "mount_path": "/workspace/repo",
        "authorization_token": "ghp_...",
        "branch": "feature-branch"
      }
    ]
  }'

Send a User Message

curl -X POST https://api.anthropic.com/v1/sessions/$SESSION_ID/events \
  "${HEADERS[@]}" \
  -d '{
    "events": [
      {
        "type": "user.message",
        "content": [{ "type": "text", "text": "Review the auth module for security issues" }]
      }
    ]
  }'

Stream Events (SSE)

curl -N https://api.anthropic.com/v1/sessions/$SESSION_ID/events/stream \
  "${HEADERS[@]}"

Response format:

event: session.status_running
data: {"type":"session.status_running","id":"sevt_...","processed_at":"..."}

event: agent.message
data: {"type":"agent.message","id":"sevt_...","content":[{"type":"text","text":"I'll review..."}],"processed_at":"..."}

event: session.status_idle
data: {"type":"session.status_idle","id":"sevt_...","processed_at":"..."}

Poll Events

# Get all events
curl https://api.anthropic.com/v1/sessions/$SESSION_ID/events \
  "${HEADERS[@]}"

# Paginated — get next page of events
curl "https://api.anthropic.com/v1/sessions/$SESSION_ID/events?page=page_abc123" \
  "${HEADERS[@]}"

Provide Custom Tool Result

When the agent calls a custom tool, send the result back:

curl -X POST https://api.anthropic.com/v1/sessions/$SESSION_ID/events \
  "${HEADERS[@]}" \
  -d '{
    "events": [
      {
        "type": "user.custom_tool_result",
        "custom_tool_use_id": "sevt_abc123",
        "content": [{ "type": "text", "text": "No linting errors found." }]
      }
    ]
  }'

Interrupt a Running Session

curl -X POST https://api.anthropic.com/v1/sessions/$SESSION_ID/events \
  "${HEADERS[@]}" \
  -d '{
    "events": [
      {
        "type": "interrupt"
      }
    ]
  }'

Get Session Details

curl https://api.anthropic.com/v1/sessions/$SESSION_ID \
  "${HEADERS[@]}"

List Sessions

curl https://api.anthropic.com/v1/sessions \
  "${HEADERS[@]}"

Delete a Session

curl -X DELETE https://api.anthropic.com/v1/sessions/$SESSION_ID \
  "${HEADERS[@]}"

Upload a File

curl -X POST https://api.anthropic.com/v1/files \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: files-api-2025-04-14" \
  -F "file=@path/to/file.txt" \
  -F "purpose=agent"

List and Download Session Files

List files the agent wrote to /mnt/session/outputs/ during a session, then download them.

# List files associated with a session
curl "https://api.anthropic.com/v1/files?scope_id=$SESSION_ID" \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: files-api-2025-04-14,managed-agents-2026-04-01"

# Download a specific file
curl "https://api.anthropic.com/v1/files/$FILE_ID/content" \
  -H "x-api-key: $ANTHROPIC_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "anthropic-beta: files-api-2025-04-14,managed-agents-2026-04-01" \
  -o downloaded_file.txt

List Agents

curl https://api.anthropic.com/v1/agents \
  "${HEADERS[@]}"

MCP Server Integration

# 1. Agent declares MCP server (no auth here — auth goes in a vault)
curl -X POST https://api.anthropic.com/v1/agents \
  "${HEADERS[@]}" \
  -d '{
    "name": "MCP Agent",
    "model": "claude-opus-4-7",
    "mcp_servers": [
      { "type": "url", "name": "my-tools", "url": "https://my-mcp-server.example.com/sse" }
    ],
    "tools": [
      { "type": "agent_toolset_20260401" },
      { "type": "mcp_toolset", "mcp_server_name": "my-tools" }
    ]
  }'

# 2. Session attaches vault containing credentials for that MCP server URL
curl -X POST https://api.anthropic.com/v1/sessions \
  "${HEADERS[@]}" \
  -d '{
    "agent": "agent_abc123",
    "environment_id": "env_abc123",
    "vault_ids": ["vlt_abc123"]
  }'

See shared/managed-agents-tools.md §Vaults for creating vaults and adding credentials.
