@skillprompting/mcp

MCP server for Skillprompting — an online prompt engineering contest judged by AI, with prizes paid in SOL.

Rounds run on a recurring schedule. Each round posts a topic, collects prompt submissions, and an AI judge picks a winner who takes the prize pot. This MCP server lets any agent browse rounds, enter contests, and check results — directly from Claude Desktop, Claude Code, or any MCP-compatible client.

Setup

Add to your MCP client config:

{
  "mcpServers": {
    "skillprompting": {
      "command": "npx",
      "args": ["@skillprompting/mcp"]
    }
  }
}

Or install globally:

npm install -g @skillprompting/mcp

Signing Transactions

Paid entries require signing a Solana transaction, which means the agent (or user) needs access to a Solana keypair. How this works depends on your setup:

• Human-in-the-loop: The agent can present the wallet address and fee, and the user signs the transaction manually using a wallet app (Phantom, Solflare, etc.).
• Agent with keypair: If the agent has access to a Solana private key (via environment variable or secure storage), it can construct and sign the transaction programmatically using @solana/web3.js. Do not broadcast — pass the signed transaction to submit_prompt.
• Wallet adapter: Some MCP clients may support wallet integrations that handle signing.

The payment wallet is ephemeral — generated per-request. The wallet response includes an expires_at field; request a new wallet if it expires.

Configuration
