Weather MCP Server

Model Context Protocol server with integrated micropayment functionality. Built with Bun, TypeScript, and the ATXP payment system for monetizing LLM tool calls.

Features

MCP Protocol: Standardized tool interface for AI assistants
Payment Integration: ATXP middleware requiring USDC micropayments per tool call
Stateless Architecture: Per-request transport isolation for scalability
Type-Safe: Strict TypeScript with Zod v3 validation
High Performance: Bun runtime for fast execution

Tech Stack

Runtime: Bun
Protocol: MCP
Payment: ATXP
Validation: Zod v3
Server: Express v5

Quick Start

# Install bun install # Configure .env ATXP_CONNECTION="your-atxp-connection-url" PORT=3000 # Development bun run dev # Production bun run build bun run start

Architecture

Client → Express → ATXP Payment → MCP Transport → Tool Handler → Response

Each tool call validates payment before execution. The server creates a new StreamableHTTPServerTransport per request to prevent JSON-RPC ID collisions.

Tool Registration

server.registerTool( "tool-name", { title: "Tool Title", description: "What it does", inputSchema: { param: z.string() }, outputSchema: { result: z.string() } }, async (params) => { await requirePayment({ price: BigNumber(0.01) }); return { content: [{ type: "text", text: JSON.stringify(output) }], structuredContent: output }; } );

API

POST / - Accepts MCP JSON-RPC 2.0 requests

{ "jsonrpc": "2.0", "method": "tools/call", "params": { "name": "tool-name", "arguments": {} }, "id": 1 }

TypeScript Config

verbatimModuleSyntax: true - Explicit type imports required
