MCP is a protocol for connecting AI applications to external tools and context. The host is the application using the model; a client is its protocol connection to a server; a server exposes supported capabilities. The model normally proposes operations,…
REST is an HTTP API design style for application services. Function calling is a model interaction mechanism for proposing structured operations. MCP standardizes integration discovery and invocation/context exchange; a plugin is a packaging/integration…
Resources expose readable context through identified locations, such as policy documents. Prompts expose reusable task templates and arguments. Tools perform operations; resources provide content; prompts help compose a task.
AI and LLM fundamentals
A tool is a named executable capability with argument metadata and a schema. Discovery lets a client obtain the server's available tool descriptions. A tool description helps the model choose a capability; it is not proof that the server or tool is…
Authentication establishes who a client/user is; authorization determines what that identity may do. MCP connection authorization and downstream business authorization are separate concerns. A valid connection does not automatically permit every customer's…
LangGraph essentials: nodes return state updates; reducers define merge behavior; edges control next steps; model routes need validation; production needs durable checkpoint storage and authorized threads. An interrupted node can restart, so pre-pause side…
This example defines server-side contracts and dispatch logic, not a particular MCP SDK's registration syntax. Attach this registry to the selected SDK's authenticated request handlers, implement capability discovery, and encode its documented result…
