Frequently asked
What is the difference between Model Context Protocol and MCP Server?
Model Context Protocol: MCP is an open standard for connecting LLMs to external tools and data sources. It defines a JSON-RPC protocol so any client (Claude Desktop, Cursor, IDE plugins) can talk to any MCP server. MCP Server: An MCP server exposes tools, resources, or prompts via the Model Context Protocol so any compliant client (Claude Desktop, Cursor, IDE plugins) can call them without bespoke integration.
When should I use Model Context Protocol vs MCP Server?
Model Context Protocol is the right concept when you are focused on agents & tools. When the same tools need to be available to multiple AI clients, or when you want to expose internal capabilities to LLM applications without writing per-app glue.
Are Model Context Protocol and MCP Server the same thing?
No. Model Context Protocol is agents & tools; MCP Server is agents & tools. They are related but address different parts of the AI stack.
