About this tool
Base MCP Protocol
Description
The Base MCP Protocol defines the standard protocol and architecture for Model Context Protocol (MCP) servers, ensuring universal compatibility and standardized interfaces for AI-powered tool integration. It establishes a modular, extensible foundation for communication between clients and servers in AI applications.
Features
Core Protocol
- JSON-RPC 2.0 Compliance: All messages between MCP clients and servers adhere to JSON-RPC 2.0.
- Requests: Initiate operations, include unique ID and method name.
- Responses: Reply to requests, include the same ID as the request (can be results or errors).
- Notifications: One-way messages, no reply, must not include an ID.
- Error Handling: Errors in responses must include an error code and message.
Protocol Layers
- Base Protocol: Defines core message types and interactions.
- Lifecycle Management: Manages connection initialization, capability negotiation, and session control.
- Server Features:
- Prompts: Server-side prompt management.
- Resources: Server-exposed resources.
- Tools: Tools exposed by servers for client use.
- Utilities: Includes completion, logging, and pagination utilities.
- Client Features:
- Sampling: Mechanisms for sampling data or responses.
- Roots: Directory-like listing of root resources.
- Utilities: Cross-cutting concerns such as logging, argument completion, and progress reporting.
Authorization
- Auth Framework: Provides an authorization framework for HTTP+SSE transport.
- Custom Auth Strategies: Allows clients and servers to negotiate custom authentication/authorization methods.
- STDIO Transport: Uses environment credentials instead of the HTTP+SSE framework.
Schema
- TypeScript Schema: Full protocol specified as a TypeScript schema, serving as the source of truth.
- JSON Schema: Automatically generated from the TypeScript source for use with automated tooling.
Modularity
- Modular Design: Implementations can support only the components needed for their application, ensuring flexibility and scalability.
- Clear Separation of Concerns: Each protocol layer and component is well-defined and separated.
