Onchain Agent Wallets
MCP server for giving AI agents bounded Solana spending allowances without handing over the owner wallet private key. It uses real SPL Token delegations, revocable custody, configurable guardrails and x402 payment support so an agent can spend within a capped allowance and the user can revoke access in one transaction. Public GitHub repository created August 19, 2026.
