Small utility helpers and shared Zod input schemas for the WebBlackbox MCP (Model Context Protocol) server and related integrations.

Installation

npm install @webblackbox/mcp-core

Usage

Each utility exports a Zod-based input schema (for MCP tool registration) and a corresponding function:

import {
  addNumbersInput,
  addNumbers,
  nowUtcInput,
  nowUtcIsoString,
  echoInput,
  echo
} from "@webblackbox/mcp-core";

// Arithmetic helper
addNumbers({ a: 1, b: 2 }); // 3

// UTC timestamp
nowUtcIsoString(); // "2026-03-14T12:00:00.000Z"

// Echo
echo({ text: "hello" }); // "hello"

Exported Utilities

| Function | Input Schema | Description | | ---------------------- | ----------------- | ------------------------------------------------- | | addNumbers({ a, b }) | addNumbersInput | Add two finite numbers | | nowUtcIsoString() | nowUtcInput | Return the current UTC time as an ISO 8601 string | | echo({ text }) | echoInput | Echo back the provided text (1–10,000 chars) |

Each *Input export is a plain object of Zod schemas, ready to pass as the inputSchema when registering an MCP tool.
