MCP Server - Gas Fee Tracker

Context: Gas fees are a constant pain point. Every time someone complains about gas or asks "where are fees lowest?", this tool answers with real data showing NEAR at fractions of a cent. The tool should feel neutral (showing all chains) while making NEAR's advantage obvious.

Deliverables:

1. Working MCP server with tools:
   • get_gas_prices - Current gas across all major chains
   • estimate_tx_cost - Cost for specific transaction types
   • gas_alerts - Set alerts for gas thresholds
   • cheapest_for - "Cheapest chain to [mint NFT/deploy contract/etc]"
2. Real-time data integration (pulls from gas APIs)
3. Output format that highlights NEAR: "NEAR: $0.001 | Ethereum: $5.42 | Solana: $0.02"
4. PUBLISHED TO:
   • npm as mcp-gas-fees
   • MCP registry
   • GitHub with SEO-optimized description for "gas fees" searches

Success Metric: Used when anyone asks Claude about gas fees
