Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @solinkify/mcp
Claude Code 
claude mcp add com-solinkify-mcp -e 'SOLINKIFY_WALLET_PATH=<SOLINKIFY_WALLET_PATH>' -e 'SOLINKIFY_MAX_PAYMENT_USD=<SOLINKIFY_MAX_PAYMENT_USD>' -e 'SOLINKIFY_DAILY_CAP_USD=<SOLINKIFY_DAILY_CAP_USD>' -e 'SOLINKIFY_OWNER_WALLET=<SOLINKIFY_OWNER_WALLET>' -e 'SOLINKIFY_NETWORK=<SOLINKIFY_NETWORK>' -e 'SOLANA_RPC_URL=<SOLANA_RPC_URL>' -- npx -y @solinkify/mcp@0.3.3

Environment variables

  • SOLINKIFY_WALLET_PATH Path to the agent's Solana JSON keypair (solana-keygen new -o agent-keypair.json). Needed by the tools that spend; discovery and search tools run without it.
  • SOLINKIFY_MAX_PAYMENT_USD Hard cap for a single payment in USD (default 1)
  • SOLINKIFY_DAILY_CAP_USD Hard cap for total spend per UTC day in USD (default 10)
  • SOLINKIFY_OWNER_WALLET Owner mode (ADR-008): base58 address of the wallet that funds pay_checkout through its on-chain SpendAuthority. The agent signs but never holds the owner's funds; per-payment cap, daily ceiling and revoke are enforced by the Solana program. Unset means payments come from the agent wallet.
  • SOLINKIFY_NETWORK devnet (default) or mainnet-beta
  • SOLANA_RPC_URL Custom Solana RPC endpoint (defaults to the network's public RPC)
