@prismnetwork/mcp

@prismnetwork/mcp

An MCP server that lets Claude (or any MCP client) see and lease real GPUs through Prism Network. Give it a wallet and it handles auth, onchain payment, provisioning, and SSH.

Try it without a wallet

Looking costs nothing and needs no configuration:

claude mcp add prism -- npx -y @prismnetwork/mcp

Then ask what you can rent. prism_list_gpus answers from live capacity with real prices. Leasing spends money, so those tools ask for a wallet and say so.

prism_vault_delete	yes
prism_vault_release	yes

• prism_wallet: the agent's address and USDG/ETH balances.
• prism_list_gpus: GPUs available to lease, with price per second and per hour.
• prism_lease_and_run: lease a GPU, run a command, return the output (one shot).
• prism_lease: lease a GPU and keep it; returns a lease_id and SSH access.
• prism_run: run a command on an existing lease.
• prism_end_lease: release a lease.
• prism_vault_store: seal private data under the wallet-derived key.
• prism_vault_list: list sealed items; values are never returned.
• prism_vault_read: decrypt one item in this process.
• prism_vault_delete: permanently delete an item.
• prism_vault_release: authorize an item into a lease that clears its trust floor.

Vault

An agent that handles a card, an identity document or a credential should not write it into a leased workspace. prism_vault_store seals it under a key derived from the agent's wallet inside this server process; Prism receives ciphertext and holds no way to read it.

Each item names the weakest workspace trust class it may ever be released into, and new items default to confidential — above anything the network serves today. prism_vault_release is therefore refused on current capacity instead of handing a secret to a host that can read it. Lowering an item's floor is a deliberate act, and allowed releases are recorded against the account.

Configure

Point your MCP client (Claude Desktop / Code) at the published server:

{
  "mcpServers": {
    "prism": {
      "command": "npx",
      "args": ["-y", "@prismnetwork/mcp"],
      "env": {
        "PRISM_AGENT_KEY": "0x<agent wallet private key>",
        "PRISM_ESCROW": "0x71Df0eF3bc81022cB3bec0b1a05f52f12bAfcDeD"
      }
    }
  }
}

The wallet needs USDG (0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168) and Robinhood-Chain ETH for gas. See the SDK's Funding section for how to fund a fresh wallet.

Or add it to Claude Code in one line:

claude mcp add prism \
  --env PRISM_ESCROW=0x71Df0eF3bc81022cB3bec0b1a05f52f12bAfcDeD \
  --env PRISM_AGENT_KEY=0x<agent wallet private key> \
  -- npx -y @prismnetwork/mcp

Timing

prism_lease and prism_lease_and_run block while a GPU provisions (usually one to four minutes, occasionally longer on a slow host). Configure your MCP client to allow long tool calls.
