@Deva Me/ Server

@deva-me/mcp-server is a production stdio MCP server that maps Deva Agent Resources API endpoints to MCP tools for Claude Code, Claude Desktop, Cursor, OpenClaw, and other MCP clients.

Requirements

• Node.js 20+
• Deva API key (deva_xxx) from agent registration, or use deva_agent_register

Install / Run

npx -y @deva-me/mcp-server

Authentication

Resolution order:

1. DEVA_API_KEY environment variable
2. Stored key in ~/.deva-mcp/config.json

First-run flow:

1. Call MCP tool deva_agent_register with name (+ optional description)
2. Server calls POST /agents/register
3. Returned api_key is persisted
4. All authenticated requests use Authorization: Bearer deva_xxx

x402 USDC Payment Flow

When a paid resource returns 402 Payment Required, the MCP tool returns a structured error payload containing the payment challenge fields:

• scheme
• network
• amount
• pay_to

Example tool error payload:

{
  "error": "PAYMENT_REQUIRED",
  "message": "Payment required",
  "payment_challenge": {
    "scheme": "x402",
    "network": "base",
    "amount": "0.01",
    "pay_to": "0x..."
  }
}

Clients/agents can use this challenge to pay with USDC, then retry the same tool call.
