@deva-me/mcp-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

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

Pricing (Current)

Use deva_cost_estimate before execution and deva_resources_catalog for live catalog/pricing from the API.

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:

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