Numbers API

What is the Numbers API MCP Server?

Equip your AI agent with interesting facts and historical context for any number or date via the Numbers API. This server provides instant access to trivia, mathematical properties, and historical events associated with specific numbers and years. Your agent can retrieve date-specific facts, audit mathematical patterns, and provide random interesting context for numerical data without any manual search. Whether you are adding color to a presentation or verifying historical timelines, your agent acts as a dedicated numerical encyclopedia through natural conversation.

What you can do

  • Trivia Discovery — Retrieve fun and unusual facts for any integer or random number.
  • Math Intelligence — Access technical mathematical properties and interesting patterns for specific numbers.
  • Date Auditing — Fetch historical events that occurred on any specific month and day of the year.
  • Yearly Context — Retrieve significant historical milestones and facts for any given year.
  • Random Inspiration — Get a completely random fact across all categories to discover new knowledge.

How it works

  1. Subscribe to this server
  2. No API Key required (Free Public API)
  3. Start exploring number intelligence from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Educators & Students — find interesting mathematical and historical context for classroom activities.
  • Content Creators — retrieve trivia and milestones to enrich articles, videos, and social media posts.
  • History Enthusiasts — explore what happened on specific dates or years throughout human history.
  • Developers — integrate dynamic and interesting numerical context into their applications.
  • Data Storytellers — add human-readable context to purely numerical data points.

Why OpenAI Agents SDK?

The OpenAI Agents SDK auto-discovers all 5 tools from Numbers API through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries Numbers API, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

  • Native MCP integration via MCPServerSse, pass the URL and the SDK auto-discovers all tools with full type safety

  • Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

  • Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

  • First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

FAQ

Frequently asked questions

01

Do I need an API key to use this server?

No, the Numbers API is completely free and does not require any authentication or API keys.

02

Can I search for facts about specific dates like my birthday?

Yes! Use the get_date_fact tool and provide the month and day. Your agent will return a historical event associated with that specific calendar day.

03

What kind of mathematical facts are available?

The get_math_fact tool provides properties like whether a number is a prime, Fibonacci number, perfect number, or has other unique mathematical characteristics.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.

07
