How to initialize a server and add tools?

[huhu415]

I want to initialize a server, but I got an error when initializing this project. How should I fix it?

Another thing is how to add tools to the server? I didn't see any documentation about this

I now know how to initialize, but how do I add tools?

Apologies for the slow reply. In case you haven't figured it out yet, here is a snippet that shows how.

let server = Server(name: "Example Server",
                        version: "1.0",
                        capabilities: Server.Capabilities(logging: nil,
                                                          prompts: nil,
                                                          resources: nil,
                                                          
                                                          tools: .init(listChanged: false)))

 await server.withMethodHandler(ListTools.self) { context in
            
    let tool1Schema: [String: Value] = ["properties":
                                                    ["param1": ["description": "An example parameter",
                                                                "type": "string"]],
                                                "$schema": "http://json-schema.org/draft-07/schema#",
                                                "additionalProperties": false,
                                                "required": ["param1"],
                                                "type": "object"]
            
     let myTool1 = Tool(name: "MyTool1",
                              description: "Something something, tool, something something",
                              inputSchema: .object(tool1Schema))
            
            
            return ListTools.Result(tools: [myTool1])
        }
    
        
await server.withMethodHandler(CallTool.self) { context in
            
            switch context.name {
                case "MyTool1":
                    return CallTool.Result(content: [.text("Tool 1 called with: \(String(describing: context.arguments))")])
                default:
                    throw MCPError.methodNotFound(context.name)
            }
            
        }
