Add dynamic tool update example for Model Context Protocol
Implement a new example demonstrating how MCP servers can dynamically update available tools at runtime and how clients can detect these changes. - Add Server implementation that starts with weather forecast tools and dynamically adds math operation tools - Add Client implementation that detects tool changes via MCP notifications - Complete client/server architecture with proper tool registration and discovery - Add detailed README explaining the dynamic tool update process and implementation Signed-off-by: Christian Tzolov <christian.tzolov@broadcom.com>

# Dynamic Tool Update Example
|
||||
|
||||
This example demonstrates how a Model Context Protocol (MCP) server can dynamically update its available tools at runtime, and how a client can detect and use these updated tools.
|
||||
|
||||
## Overview
|
||||
|
||||
The MCP protocol allows AI models to access external tools and resources through a standardized interface. This example showcases a key feature of MCP: the ability to dynamically update the available tools on the server side, with the client detecting and utilizing these changes.
|
||||
|
||||
## Key Components
|
||||
|
||||
### Server
|
||||
|
||||
The server application consists of:
|
||||
|
||||
1. **WeatherService**: Initially provides a weather forecast tool that retrieves temperature data for a specific location.
|
||||
2. **MathTools**: Contains mathematical operations (sum, multiply, divide) that are added dynamically to the server.
|
||||
3. **ServerApplication**: Manages the server lifecycle and handles the dynamic tool update process.
|
||||
|
||||
### Client
|
||||
|
||||
The client application:
|
||||
|
||||
1. Connects to the MCP server
|
||||
2. Retrieves the initial list of available tools
|
||||
3. Triggers the server to update its tools
|
||||
4. Detects the tool changes
|
||||
5. Retrieves the updated list of tools
|
||||
|
||||
## How It Works
|
||||
|
||||
1. **Initial Setup**: When the server starts, it only exposes the weather forecast tool.
|
||||
|
||||
2. **Dynamic Update Process**:
|
||||
- The client sends a request to the server's `/updateTools` endpoint
|
||||
- The server receives this signal and adds the math tools to its available tools
|
||||
- The server notifies connected clients about the tool changes
|
||||
- The client receives the notification and can now use the new tools
|
||||
|
||||
3. **Tool Discovery**: The client can query the available tools at any time, demonstrating that the tool list has been updated.
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Server-Side Implementation
|
||||
|
||||
The server uses Spring AI's MCP server implementation:
|
||||
|
||||
```java
|
||||
@Bean
|
||||
public ToolCallbackProvider weatherTools(WeatherService weatherService) {
|
||||
return MethodToolCallbackProvider.builder().toolObjects(weatherService).build();
|
||||
}
|
||||
|
||||
@Bean
|
||||
public CommandLineRunner predefinedQuestions(McpSyncServer mcpSyncServer) {
|
||||
return args -> {
|
||||
logger.info("Server: " + mcpSyncServer.getServerInfo());
|
||||
|
||||
latch.await(); // Wait for update signal
|
||||
|
||||
// Add math tools dynamically
|
||||
List<SyncToolSpecification> newTools = McpToolUtils
|
||||
.toSyncToolSpecifications(ToolCallbacks.from(new MathTools()));
|
||||
|
||||
mcpSyncServer.addTool(newTools.iterator().next());
|
||||
|
||||
logger.info("Tools updated: ");
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Client-Side Implementation
|
||||
|
||||
The client connects to the server and registers a callback to be notified when tools change:
|
||||
|
||||
```java
|
||||
@Bean
|
||||
McpSyncClientCustomizer customizeMcpClient() {
|
||||
return (name, mcpClientSpec) -> {
|
||||
mcpClientSpec.toolsChangeConsumer(tv -> {
|
||||
logger.info("\nMCP TOOLS CHANGE: " + tv);
|
||||
latch.countDown();
|
||||
});
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
The client retrieves the available tools before and after the update:
|
||||
|
||||
```java
|
||||
// Get initial tools
|
||||
List<ToolDescription> toolDescriptions = chatClientBuilder.build()
|
||||
.prompt("What tools are available?")
|
||||
.toolCallbacks(tools)
|
||||
.call()
|
||||
.entity(new ParameterizedTypeReference<List<ToolDescription>>() {});
|
||||
|
||||
// Signal the server to update tools
|
||||
String signal = RestClient.builder().build().get()
|
||||
.uri("http://localhost:8080/updateTools").retrieve().body(String.class);
|
||||
|
||||
// Wait for tool change notification
|
||||
latch.await();
|
||||
|
||||
// Get updated tools
|
||||
toolDescriptions = chatClientBuilder.build()
|
||||
.prompt("What tools are available?")
|
||||
.toolCallbacks(tools)
|
||||
.call()
|
||||
.entity(new ParameterizedTypeReference<List<ToolDescription>>() {});
|
||||
```
|
||||
|
||||
## Key Insight
|
||||
|
||||
The example demonstrates a crucial aspect of the MCP implementation in Spring AI:
|
||||
|
||||
> The client implementation relies on the fact that the `ToolCallbackProvider#getToolCallbacks` implementation for MCP will always get the current list of MCP tools from the server.
|
||||
|
||||
This means that whenever a client requests the available tools, it will always get the most up-to-date list from the server, without needing to restart or reinitialize the client.
|
||||
|
||||
## Running the Example
|
||||
|
||||
1. Start the server application:
|
||||
```
|
||||
cd server
|
||||
./mvnw spring-boot:run
|
||||
```
|
||||
|
||||
2. In a separate terminal, start the client application:
|
||||
```
|
||||
cd client
|
||||
./mvnw spring-boot:run
|
||||
```
|
||||
|
||||
3. Observe the console output to see:
|
||||
- The initial list of tools (only weather forecast)
|
||||
- The tool update notification
|
||||
- The updated list of tools (weather forecast + math operations)
|
||||
|
||||
