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.

GitHub Copilot Agent mode brings Numbers API data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 5 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.

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.

Numbers API + VS Code Copilot FAQ

Common questions about integrating Numbers API MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
