This appendix provides supplementary information, including a glossary of common MCP terms and a list of useful resources to help you further explore and work with the Model Context Protocol.

Glossary of MCP Terms

Section titled “Glossary of MCP Terms”
  • Client (MCP Client): An application or component that consumes services from an MCP Server. Clients request resources, invoke prompts, and call tools to provide context to LLMs or automate tasks.
  • Server (MCP Server): An application or component that implements the MCP specification to expose data and capabilities. Servers provide resources, prompts, and tools to connected MCP Clients.
  • Resource: A piece of contextual information provided by an MCP Server (e.g., a file, a database record, a calendar event). Resources are typically identified by a URI and fetched using the mcp_getResource method.
  • Prompt (MCP Prompt): A server-exposed capability that allows a client to request the server to construct a prompt for an LLM, often incorporating contextual information from its resources. Invoked using mcp_invokePrompt.
  • Tool (MCP Tool): A server-exposed capability that allows a client to request the server to perform an action or computation. Tools can have side effects (e.g., sending an email, updating a database). Invoked using mcp_invokeTool.
  • Capabilities: The set of features, methods, and specifications supported by an MCP Client or Server. Negotiated upon connection using methods like mcp_getCapabilities.
  • JSON-RPC: The remote procedure call protocol format used by MCP for structuring requests and responses. MCP messages are JSON-RPC 2.0 messages.
  • Host Application: An application that embeds or manages MCP clients and/or servers, such as an IDE, a desktop application, or a web service.
  • Transport: The underlying communication mechanism used to exchange MCP messages (e.g., WebSockets, HTTP, IPC).
  • MCP Inspector: A utility (if available) for developers to connect to, test, and debug MCP servers by directly invoking methods and inspecting responses.
  • SDK (Software Development Kit): Libraries provided to simplify the development of MCP clients and servers in specific programming languages (e.g., TypeScript, Python).
