Implementation Reference
- src/tools/tool-add.ts:13-24 (handler)The async handler function for the 'add' tool. It validates the input arguments using AddSchema, computes the sum of 'a' and 'b', and returns a structured text response containing the result.
handler: async (args: any) => { const validatedArgs = AddSchema.parse(args); const sum = validatedArgs.a + validatedArgs.b; return { content: [ { type: "text" as const, text: `The sum of ${validatedArgs.a} and ${validatedArgs.b} is ${sum}.`, }, ], }; }, - src/tools/tool-add.ts:4-7 (schema)Zod schema (AddSchema) defining the input structure for the 'add' tool: two number fields 'a' and 'b' with descriptions.
const AddSchema = z.object({ a: z.number().describe("First number"), b: z.number().describe("Second number"), }); - src/tools/index.ts:22-37 (registration)Registration of the 'add' tool by including 'addTool' in the 'allTools' array, which is used by getTools() for listing tools and getToolHandler() for execution dispatching.
const allTools = [ echoTool, addTool, longRunningOperationTool, printEnvTool, sampleLlmTool, sampleWithPreferencesTool, sampleMultimodalTool, sampleConversationTool, sampleAdvancedTool, getTinyImageTool, annotatedMessageTool, getResourceReferenceTool, elicitationTool, getResourceLinksTool, ]; - src/tools/index.ts:8-8 (registration)Import statement that brings the 'addTool' into the index module for registration.
