agentmetal/mcp

MCP server that exposes AgentMetal as tools, so an agent can discover → pay → provision → SSH in → run commands → manage → renew its own Linux server (VPS / cloud instance) with no human signup. Paid tools sign USDC payments over x402 v2 (or pay by card); the rest are plain HTTP.

Tools

13 tools. Paid tools sign a USDC/x402 payment; account-gated tools need AGENTMETAL_API_KEY (am_live_…) and ownership of the server.

Tool	Pays?	Account key?	What it does
get_catalog	—	—	List plans, locations, and add-on pricing (bandwidth, storage). The free discovery hook.
provision_server	✅ USDC	—	Provision a VPS (plan, days, optional ssh_key/via, managed_key) → id, IPv4, SSH. With managed_key:true, a server-side keypair is generated, authorized, and the private key returned once (stored only encrypted) to enable exec_command.
get_server	—	—	Status, IPv4, expiry, bandwidth, storage for a server id
list_servers	—	—	Fleet for a wallet/account
extend_server	✅ USDC	—	Extend a lease by N days
destroy_server	—	✅	Destroy now
reboot_server	—	✅	Soft-reboot an owned server
server_logs	—	✅	Hypervisor-level diagnostics without logging in: status, recent provider actions, a VNC console URL, and live CPU/disk/net metrics (no text boot log exists provider-side)
exec_command	—	✅	Run a shell command as root over SSH → exit_code/stdout/stderr. Requires a server provisioned with managed_key:true. Bounded: 1–120 s timeout, 256 KB output cap.
get_firewall	—	—	Read a box's edge-firewall rules. Callable from the box itself (source-IP identity) or with an account key.
manage_firewall	—	—	Open/close inbound ports on a box's edge firewall (protocol/port/source_ips). From the box itself or with an account key; SSH-lockout guarded.
claim_account	—	—	Email a one-time claim code (via AWS SES)
verify_claim	—	—	Redeem the code for an account API key. Link a wallet by also passing wallet + wallet_signature.

Add-ons (currently API endpoints, not yet separate MCP tools): extra storage ($0.01/GB/day, attached block volume) via POST /v1/servers/{id}/storage and extra bandwidth ($2/TB beyond the 20 TB included) via POST /v1/servers/{id}/bandwidth.

Configuration (env)

Var	Default	Purpose
AGENTMETAL_BASE_URL	https://api.agentmetal.dev	API base URL
WALLET_PRIVATE_KEY	—	0x… EVM key used to pay 402s. Omit and paid tools fail with a clear message.
AGENTMETAL_NETWORK	eip155:8453	CAIP-2 network (Base mainnet)
AGENTMETAL_MAX_USDC	50	Per-request spend cap, in USDC
AGENTMETAL_API_KEY	—	am_live_… account key, required for destroy_server / reboot_server / server_logs / exec_command

Use with Claude Code

// .mcp.json (or claude mcp add)
{
  "mcpServers": {
    "agentmetal": {
      "command": "node",
      "args": ["packages/mcp/src/index.ts"],
      "env": {
        "WALLET_PRIVATE_KEY": "0x…",
        "AGENTMETAL_MAX_USDC": "50"
      }
    }
  }
}

The wallet must hold USDC on Base. The spend cap (AGENTMETAL_MAX_USDC) bounds what any single tool call can pay; a 402 above the cap is refused before signing.

Status: client + server are unit-tested and the stdio handshake is verified. Live USDC settlement needs a funded wallet + an x402 facilitator that supports the exact / eip155:8453 kind.
