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

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.

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.

About 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.

Google ADK natively supports Numbers API as an MCP tool provider. declare Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 5 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.

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.

The Numbers API MCP Server exposes 5 tools through the Vinkius. Connect it to Google ADK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Numbers API + Google ADK FAQ

Common questions about integrating Numbers API MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
