DeskFerry vs Claude Managed Agents

import Anthropic from "@anthropic-ai/sdk";
const client = new Anthropic();

// Once: where tools run
const environment = await client.beta.environments.create({
  name: "ops-env",
  config: { type: "cloud", networking: { type: "unrestricted" } },
});

// Once: the agent (persisted and versioned)
const agent = await client.beta.agents.create({
  name: "Invoice chaser",
  model: "claude-opus-5",
  system: "Chase overdue invoices politely. Ask before sending.",
  mcp_servers: [{ type: "url", name: "billing", url: MCP_URL }],
  tools: [
    { type: "agent_toolset_20260401", default_config: { enabled: true } },
    { type: "mcp_toolset", mcp_server_name: "billing" },
  ],
});

// Every run: a session, then send a message and stream events
const session = await client.beta.sessions.create({
  agent: agent.id,
  environment_id: environment.id,
  vault_ids: [vault.id], // credentials for the MCP server
});

Powerful and flexible. You still build the MCP server or pick one, store credentials in a vault, handle the event stream, and give people a way to use it.
