Which language should I use for MCP development?

TypeScript is generally recommended for production-grade servers due to robust SDK support, while Python is excellent for data science and quick CLI integrations.

What is the difference between a Tool and a Resource?

Tools are executable functions that Claude calls to perform actions, while Resources are data sources (like files or API responses) that Claude can read as context.

How do I test my custom MCP server?

You can use the official MCP Inspector utility (npx @modelcontextprotocol/inspector) to manually test tool calls and resource reading before deployment.

What is an MCP Server?

An MCP (Model Context Protocol) server is a standardized integration that allows Claude to securely interact with local tools, external APIs, and data resources.

How do I optimize tools for Claude Code auto-discovery?

Use descriptive tool names and include specific keywords in the description to help the MCPSearch utility find your tools when context usage is high.
