MCP Servers Collection

What is MCP Servers Collection?

MCP Servers Collection is a repository containing multiple Model Context Protocol (MCP) servers that demonstrate various functionality and use cases. Each server implements specific tools accessible through a standardized MCP interface. It is intended for developers building or integrating with MCP‑compatible clients.

How to use MCP Servers Collection?

To use any server, navigate to its directory (e.g., mcp-calculator-server), run npm install, build if necessary (npm run build for TypeScript-based servers), then start via npm start. The calculator server is used as cd mcp-calculator-server && npm start; the weather server is used as a command‑line tool after building.

Key features of MCP Servers Collection

• Basic arithmetic operations (add, subtract, multiply, divide) via calculator server
• Real‑time streaming responses using Server‑Sent Events (SSE)
• Weather data retrieval via the weather server
• Comprehensive file management: list, read, write, delete, move/rename files, get metadata, and glob‑based search
• All servers use MCP SDK, Zod validation, and follow the MCP specification

Use cases of MCP Servers Collection

• An AI agent performing arithmetic operations through a standardized tool
• Real‑time calculator responses for interactive web applications
• Fetching weather information on demand via an MCP‑aware client
• Managing files (reading, writing, deleting, searching) within an MCP ecosystem

FAQ from MCP Servers Collection

What dependencies do the servers require?

All servers depend on @modelcontextprotocol/sdk and zod. Additional dependencies vary: the SSE calculator uses express and cors; the file manager uses glob.

How do I start a server?

First run npm install in the server directory, then if the server uses TypeScript run npm run build, finally start with npm start. Specific servers may provide alternative commands (e.g., the weather server runs as weather).

Can these servers be used with any MCP‑compatible client?

Yes. They work with AI agents implementing MCP, web applications using MCP, and command‑line interfaces that support the protocol.

Do any servers require building before use?

Yes, TypeScript‑based servers (e.g., the weather server) require npm run build to compile before they can be started.

What is the common pattern across all servers?

Each server uses the MCP SDK, implements one or more tools following the MCP specification, and uses Zod for input validation.
