At a Glance & Executive Verdict
Agentmetal MCP
Cloud Platforms · Remote HTTP/SSE
Quality: 55/100 (Good) | Auth: API Key required
Terraform MCP Server
Cloud Platforms · Local stdio
Quality: 74/100 (Great) | Auth: API Key required
Verdict Summary: Choose Agentmetal MCP if you need specialized Cloud Platforms tools running via a hosted cloud SSE transport. Choose Terraform MCP Server if your workspace requires Cloud Platforms integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Agentmetal MCP when:
You need dedicated capabilities in the Cloud Platforms domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
You have access to required keys: AGENTMETAL_BASE_URL, WALLET_PRIVATE_KEY, AGENTMETAL_NETWORK, AGENTMETAL_MAX_USDC, AGENTMETAL_API_KEY.
You need dedicated capabilities in the Cloud Platforms domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
You have access to required keys: TFE_ADDRESS, TFE_TOKEN, TF_MCP_SHARED_SECRET, TFE_SKIP_TLS_VERIFY, LOG_LEVEL, LOG_FORMAT, TRANSPORT_MODE, TRANSPORT_HOST.
Provision, SSH into, run commands on, and manage Linux VPSes from an agent — pay USDC over x402 or by card over HTTP 402, a running box in under 60s. No signup, no API key to buy.
The official Terraform MCP Server seamlessly integrates with the Terraform ecosystem, enabling provider discovery, module analysis, and direct Registry API integration for advanced Infrastructure as Code workflows.
Tools & Capabilities Breakdown
Agentmetal MCP Tools (13)
get_catalog
List plans, locations, and add-on pricing (bandwidth, storage). The free discovery hook.
provision_server
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
Extend a lease by N days
destroy_server
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Agentmetal MCP is categorized under Cloud Platforms and uses a remote streaming HTTP/SSE transport. In contrast, Terraform MCP Server belongs to Cloud Platforms using local stdio subprocess. Select Agentmetal MCP when you need capabilities focused on cloud platforms and Terraform MCP Server when you require tools for cloud platforms.
Primary tools included: Supports stdio and streamable HTTP transports, Direct integration with public Terraform Registry APIs, Full workspace and run management for Terraform Enterprise/HCP.
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)
