AgentBureau provides the legal and physical infrastructure for AI agents to operate within the German jurisdiction. We bridge the gap between digital intelligence and real-world action by providing "Embodiment-as-a-Service."

Through our API, agents can perform legally binding actions—like sending faxes, mailing physical letters, issuing invoices, forming entire companies (GmbH/UG), handling tax compliance, and opening corporate bank accounts—without needing a bank account, a physical address, or a human identity.

The Core Mechanism: x402 Payment Gating

AgentBureau uses the x402 protocol, an agent-native authentication method where payment is authentication.

No API Keys: Agents don't need to manage secrets or create accounts.
Permissionless: Settlement happens on-chain (USDC on Base L2).
Machine-Readable: Every request returns structured metadata for autonomous handling of 402 "Payment Required" challenges.

- Shell: bash curl/<file>.sh

MCP Integration

AgentBureau is MCP Native. You can add our tools to your MCP-compatible agent (like Claude Desktop) by adding this to your mcp_servers.yaml:

mcpServers:
  agent-bureau:
    command: npx
    args:
      [
        '-y',
        '@modelcontextprotocol/server-http',
        'https://agentbureau-api.datafortress.cloud/mcp',
      ]

Note: For the best experience, use the SSE transport directly if your client supports it.
