Types

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server implements a comprehensive test server that exercises all features of the MCP protocol. It provides implementations of prompts, tools, resources, and sampling capabilities primarily for testing MCP client implementations.

Server maintains subscriptions for resource updates and supports progress tracking and multi-level logging through dedicated channels. While not intended for production use, it serves as both a reference implementation and testing tool for MCP protocol features.

func NewServer

func NewServer() *Server

NewServer creates a new test server that implements all MCP protocol features. It initializes internal state and starts background tasks for simulating resource updates.

The server starts with debug-level logging and supports concurrent resource subscriptions through thread-safe operations. Resource updates are simulated via background goroutines to facilitate testing of client subscription handling.

Callers must call Close when finished to properly cleanup background tasks and release resources.

func (*Server) CallTool

func (s *Server) CallTool(
	ctx context.Context,
	params mcp.ToolsCallParams,
	requestClient mcp.RequestClientFunc,
) (mcp.ToolResult, error)

CallTool implements mcp.ToolServer interface.

func (Server) Close

func (s Server) Close()

Close closes the SSEServer and stops all background tasks.

func (*Server) CompletesPrompt

func (s *Server) CompletesPrompt(
	_ context.Context,
	params mcp.CompletionCompleteParams,
	_ mcp.RequestClientFunc,
) (mcp.CompletionResult, error)

CompletesPrompt implements mcp.PromptServer interface.

func (*Server) CompletesResourceTemplate

func (s *Server) CompletesResourceTemplate(
	_ context.Context,
	params mcp.CompletionCompleteParams,
	_ mcp.RequestClientFunc,
) (mcp.CompletionResult, error)

CompletesResourceTemplate implements mcp.ResourceServer interface.

func (*Server) GetPrompt

func (s *Server) GetPrompt(
	_ context.Context,
	params mcp.PromptsGetParams,
	_ mcp.RequestClientFunc,
) (mcp.PromptResult, error)

GetPrompt implements mcp.PromptServer interface.

func (Server) Info

func (s Server) Info() mcp.Info

Info implements mcp.Server interface.

func (*Server) ListPrompts

func (s *Server) ListPrompts(context.Context, mcp.PromptsListParams, mcp.RequestClientFunc) (mcp.PromptList, error)

ListResourceTemplates implements mcp.ResourceServer interface.

func (*Server) ListResources

func (s *Server) ListResources(
	_ context.Context,
