Implementation Reference
- src/index.ts:953-967 (handler)The handler function that implements the core logic of the 'get_messages' tool. It calls evolutionAPI.findMessages with instanceName, remoteJid, and optional limit, then returns the messages as a JSON-formatted text content block.
private async handleGetMessages(args: any) { const messages = await evolutionAPI.findMessages( args.instanceName, args.remoteJid, args.limit || 20 ); return { content: [ { type: 'text', text: JSON.stringify(messages, null, 2) } ] }; } - src/index.ts:413-425 (registration)Registers the 'get_messages' tool in the tools array, including its name, description, and input schema. This list is used by the MCP server for tool discovery.
