Implementation Reference
- src/handlers/cosmos-handlers.ts:614-629 (handler)MCP tool handler case: extracts blockchain and network parameters from args, calls cosmosService.getLatestBlock, and returns formatted MCP response content or error.
case 'get_cosmos_latest_block': { const blockchain = args?.blockchain as string; const network = (args?.network as 'mainnet' | 'testnet') || 'mainnet'; const result = await cosmosService.getLatestBlock(blockchain, network); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], isError: !result.success, }; } - src/handlers/cosmos-handlers.ts:302-320 (registration)Tool registration: defines the tool name, description, and input schema for validation in the registerCosmosHandlers function.
