Overview

AI-generated overview

Remote MCP server that wraps numbersapi.com, letting an assistant fetch trivia, date, math and random number facts.

What you can do
  • Look up trivia facts about a specific number, returning the fact text and the number
  • Get historical facts tied to a calendar date such as 3/14
  • Retrieve math-focused properties of a number, including prime factors and sequences
  • Pull a random number fact when no specific number is wanted
When to use it
Useful when you want quick, lightweight number or date trivia in a conversation — for example explaining why a number is notable, illustrating a historical date, or adding a surprising fact. It is a small single-purpose source rather than a general data tool.
Requirements
A remote MCP client pointed at the Pipeworx gateway endpoint; no package, API key or environment variable is declared. Network access to the gateway is required.
Before you install
Requests go through the third-party Pipeworx gateway rather than directly to numbersapi.com, so queries are visible to that operator. The README also mentions a combined gateway endpoint and an ask_pipeworx tool that gives access to many other data sources; connecting that way broadens what the assistant can reach.

Installation

In SourceWeft

  1. Open numuersapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.pipeworx-io%2Fnumbersapi/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

NumbersAPI MCP — wraps numbersapi.com (free, no auth)

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

ToolDescription
number_factGet trivia facts about a specific number (e.g., 42, 1729). Returns the fact text and number.
date_factGet historical facts about a calendar date (e.g., "3/14" for March 14). Returns the fact and date.
math_factGet mathematical properties about a number (e.g., 16, 256)—prime factors, sequences, mathematical significance. Returns math-focused trivia.
random_factGet a random trivia fact about a number. Returns the fact and the randomly chosen number. Use when you want surprising facts without specifying one.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

json
{  "mcpServers": {    "numbersapi": {      "url": "https://gateway.pipeworx.io/numbersapi/mcp"    }  }}

Or connect to the full Pipeworx gateway for access to all 673+ data sources:

json
{  "mcpServers": {    "pipeworx": {      "url": "https://gateway.pipeworx.io/mcp"    }  }}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Numbersapi data" })

The gateway picks the right tool and fills the arguments automatically.
