authorized-tools-resources-transport

Core type definitions for the Model Context Protocol, shared by other interfaces.

Type definitions for authentication and authorization

Authorization capabilities are provided at the transport level, enabling MCP clients to make requests to restricted MCP servers on behalf of resource owners.

Type definitions for resources

Resources allow servers to share data that provides context to language models, such as files, database schemas, or application-specific information. Each resource is uniquely identified by a URI.

Type definitions for the MCP lifecycle

A lifecycle for client-server connections that ensures proper capability negotiation and state management. Initialization: Capability negotiation and protocol version agreement Operation: Normal protocol communication Shutdown: Graceful termination of the connection

Type definitions for tools

Tools enable models to interact with external systems, such as querying databases, calling APIs, or performing computations. Each tool is uniquely identified by a name and includes metadata describing its schema.
