概览

What is ModelContextProtocol (MCP) Java SDK v0.8.0 Specification?

The Model Context Protocol (MCP) is a standardized protocol for communication between AI models and external tools or resources. This Java SDK provides a robust implementation, enabling Java applications to create MCP servers that expose tools and resources to AI models, as well as MCP clients that communicate with these servers.

How to use ModelContextProtocol (MCP) Java SDK v0.8.0 Specification?

Add the MCP BOM to your project's dependency management, then include the core mcp artifact. Use the builder pattern to create a McpSyncClient or McpAsyncClient, providing a transport (e.g., StdioClientTransport) and client info. Then call methods like readResource, callTool, listPrompts, or getPrompt. Close the client after use.

Key features of ModelContextProtocol (MCP) Java SDK v0.8.0 Specification

Modular architecture with separate transport, protocol, and error‑handling layers
Synchronous (McpSyncClient) and asynchronous (McpAsyncClient) client implementations
Server implementations (McpSyncServer, McpAsyncServer) for exposing resources and tools
Built‑in support for stdio transport; HTTP/SSE transport via Jakarta Servlet API
Type‑safe MCP schema classes and error utilities in dedicated packages
Full support for reading resources, calling tools, and managing prompts

Use cases of ModelContextProtocol (MCP) Java SDK v0.8.0 Specification

Build a Java MCP server that exposes file‑system resources and AI‑assistant tools
Create a synchronous client that fetches resources and calls tools from an external MCP server
Develop an asynchronous client for non‑blocking interactions with a remote MCP server
List and retrieve prompt templates from a server to generate structured AI queries

FAQ from ModelContextProtocol (MCP) Java SDK v0.8.0 Specification

What is the difference between synchronous and asynchronous clients?

McpSyncClient blocks on each call, while McpAsyncClient returns Reactor Mono objects for non‑blocking operation and requires an explicit initialize().block() call.

What transports are supported out of the box?

The SDK includes StdioClientTransport for stdio‑based communication. HTTP/SSE transports require the jakarta.servlet-api dependency (version 5.0.0, scope provided).

What are the required dependencies?

Use the MCP BOM (mcp-bom:0.8.0) for version management, then add the core mcp artifact. For HTTP/SSE, include jakarta.servlet-api:5.0.0. Testing utilities are in the mcp-test artifact.
