Fake Store API MCP Server

Instructions

Implementation Reference

• src/tools/products.ts:122-126 (handler)

  Core handler function that validates the product ID and calls the API delete endpoint to remove the product.

  export async function deleteProduct(args: { id: number }): Promise<Product> {
    const { id } = args;
    validatePositiveInteger(id, 'Product ID');
    return del<Product>(`/products/${id}`);
  }

• src/tools/products.ts:250-263 (schema)

  Tool schema definition including name, description, and input schema requiring a numeric 'id'.

  {
    name: 'fakestore_delete_product',
    description: 'Delete a product (simulation - does not persist)',
    inputSchema: {
      type: 'object',
      properties: {
        id: {
          type: 'number',
          description: 'Product ID to delete',
        },
      },
      required: ['id'],
    },
  },

• src/index.ts:109-114 (registration)

  Registration in the MCP call tool handler that dispatches to the deleteProduct function and formats the response.

  if (name === 'fakestore_delete_product') {
    const result = await deleteProduct(args as { id: number });
    return {
      content: [{ type: 'text', text: JSON.stringify(result, null, 2) }],
    };
  }

• src/index.ts:41-42 (registration)

  Tool list registration for ListToolsRequestSchema, which includes the fakestore_delete_product schema from productTools.

  return {
    tools: [...productTools, ...cartTools, ...userTools],
