ArcPay Mantle MCP

ArcPay Mantle MCP is ArcPay for AI agents. Claude Desktop, Codex-compatible hosts, and other MCP clients can ask ArcPay for Mantle deployment data, derive agent and invoice IDs, prepare x402 paid-resource flows, generate privacy/invoice instructions, build RealClaw/Byreal handoff payloads, inspect ZeroDev and Mantle DeFi/RWA evidence requirements, and return evidence checklists before claiming any work is complete.

Install

npm install -g @arcpaylabs/mantle-mcp

Claude Desktop

Add this to your Claude Desktop MCP config:

{
  "mcpServers": {
    "arcpay-mantle": {
      "command": "arcpay-mantle-mcp"
    }
  }
}

Restart Claude Desktop after editing the config.

The MCP server makes ArcPay usable by agents directly, not only by humans clicking a dashboard. It does not sign transactions or mutate treasury state; it returns deterministic IDs, integration guidance, handoff payloads, and public deployment metadata that an operator can verify before execution.

Agent-Native Flows

agent_onboarding_payload lets Claude/Codex/custom agents request the same onboarding payload a dashboard user gets: agent id, x402 endpoint, contract map, policy requirements, and claim-code steps.

usdy_card_plan lets an agent or developer prepare card issuance without touching the dashboard. It returns the card id, vault/token contracts, call sequence, and proof requirements for create/top-up/spend.

policy_plan returns both global workspace controls and per-agent controls, so an agent can explain what it is allowed to do before attempting any paid or money-moving action.

evidence_template is the guardrail: it tells the agent exactly what hashes, API responses, RealClaw evidence, venue receipts, and screenshots are required before it can claim completion.
