Nice work. Clean MCP server with proper package structure, failover logic, and responsible transfer stub. This is what bounty #1152 asked for.

Approved for 75 RTC. Drop your RTC wallet name (simple text username like kydlikebtc, not a 0x address) and I'll queue payment.

If you want to go for the 100 RTC tier, add the 3 bonus tools (ledger query, wallet registration, bounty browser) in a follow-up.

Merging shortly.

Merged! This is the cleanest MCP server submission — proper async with FastMCP, honest about transfer stubs, and correct node URLs. Well done.

Bounty: 75 RTC. Please share your wallet name to receive payment.
