Unclaimed Sol
Connects Claude and other MCP clients to the UnclaimedSOL service to scan Solana wallets for reclaimable rent from dormant token accounts, unclaimed DeFi rewards, and deactivated stake accounts. Exposes four tools: scan_claimable_sol for read-only checks, plus claim_sol, claim_rewards, and claim_stakes for transaction execution. The claiming tools use a two-step dry run and execute flow with time-limited tokens. Transactions are signed locally using your Solana keypair and broadcast through a configured RPC endpoint. Service fees range from 5% to 15% depending on claim type. Ships with pre-sign validation that enforces program allowlists and instruction layout checks before signing anything.
